1. INTRODUCTION 1.1 General product description The OPERON® B 710 operating table is a mobile operating table with an electro-hydraulic drive for executing adjustments to the table top via mains or integrated batteries. These batteries can be recharged via the mains power supply. Control of the electro-hydraulically motorised functions is carried out via a control unit connected to the operating table by a spiral cable with a plug-in connection, alternatively via the control panel in the column. The operating table top itself is divided into 5 parts, whereby only the central section is permanently fixed to the foot/column construction. All other table top modules can be removed and the operating table or table top adjusted to meet the different requirements of the various surgical disciplines by means of diverse configurations. Both the cushions and the cushion support plates of the table top are radiotranslucent, so that the OPERON® B 710 guarantees perioperative use of the X-ray image amplifier over large longitudinal areas of the table top. In addition, guide rails are located beneath the entire length of the table top; these can be used for the insertion of conventional X-ray cartridges, with the aid of an optional X-ray cassette inserter, if required. 1.2 Intended use / Product liability information The operating table is intended exclusively for human medical purposes, i.e. for the treatment of ill or injured people by means of surgical and / or medical interventions. An essential prerequisite for using the operating table is proper assembly and maintenance of the unit, as well as observance of this User Manual. Introduction for use is confirmed by a handover certificate. BERCHTOLD will only consider itself responsible for the safety characteristics, reliability and capability if • the user has been fully instructed in correct use of the operating table. • assembly, new settings, modifications or repairs are only carried out by BERCHTOLD, or by an institution expressly authorised by BERCHTOLD. • the operating table is used under ambient conditions described in chapter 11.3 in medical rooms, whose electrical installation complies with the regulations of VDE 0100-710 and IEC 60364-7-10 • the operating table is used in full compliance with these user manual. 1.3 Notes on these instructions for use Inform yourself with the help of this User Manual on the correct use of the B 710 operating table, before using it for the first time.

2. INSPECTION OF INCOMING GOODS Please check the operating table and accessories for any transport damage or defects immediately after receipt. For this purpose carry out the inspections listed in Chapter 3. below, after removing the operating table from the shipping pallet. Claims for damages will be considered only if the vendor or forwarder is informed at once. A damage report must then be prepared immediately. The damage report must be submitted to the nearest BERCHTOLD representative or to Berchtold directly, so that the claims for damages can be reported to the insurance company. When returning a unit to BERCHTOLD or a BERCHTOLD service branch, the original packaging should be used where possible. The following information must be included: owner's name and address, identification and serial number (see type plate), description of the defect.

3. REMOVING THE OPERATING TABLE FROM THE SHIPPING PALLET è Note: Never use sharp tools to open the packaging, as this could damage the contents. Attention! For safety reasons (operating table weight), the actual process of lifting the operating table from the shipping pallet have to be carried out by at least two staff members! The operating table is delivered upright on a shipping pallet. Not all the modules of the operating table top are mounted; they are enclosed and secured separately, together with any other operating accessories supplied. In order to avoid damage, the operating table have to be removed from the pallet as follows: • Remove transportation locks and separately packed components • Remove all operating table top modules (see chapter 8.12) • Prepare the operating table for operation by setting the toggle switch, which is positioned at the head side of the table base, into the upper position (see chapter 8.7). • Switch on the operating table by activating the function key 2 “ON” on the column control panel and make it ready to start by activating the function keys 4 and 5 on the column control panel (see also chapter 8.4.1). • Move the operating table to one side horizontally as far as it goes until both distant castors are placed at the edge of the pallet. • Lift one side of the operating table at the side rails of the central section and carefully place it on the floor with the castors. • Now lift the other side of the operating table, remove the pallet and place this side on the floor as well. • Immobilise the operating table again by activating function key 3 on the column control panel.

The following checks should then be performed: • Complete the operating table top by mounting all operating table top modules (see chapter 8.12) • Make the operating table ready to start again; first select the “move freely” status (see chapter 8.4.1) by activating function key 5 and check whether all castors roll easily and can be swivelled at full 360º. • Then select the “move with track stabilised” status by activating function key 6 and by slightly manoeuvring the operating table, check whether the track castor locks into place; then immobilise the operating table again. • Switch off the operating table at the column control panel again (function key 1) and connect the control unit to the operating table; the plug-in connection for the control unit is located on the left hand side below the top frame of the central section (see also chapter 8.1). Then test all powered functions by adjusting every single function into their respective end positions and back into horizontal position again. • Check the voltage supply parameter by means of the type plate for correspondence with the present mains supply before connecting the OR table to the mains. Connect the mains charging cable and check that the charging function for the batteries is operating faultlessly (see Chap 8.6 / 8.7).

4. FIRST OPERATING OF THE OR TABLE The operator may only operate the OR table when the manufacturer or supplier • has subjected the operating table to a performance check at the place of use • and the persons responsible for operation have been instructed in the correct handling of the operating table with the aid of the instructions for use.

5. IMPORTANT INFORMATION ON SAFE HANDLING (SUMMARY) Incorrect operation or failure to comply with precautionary measures can cause serious incidents, and result in injuries to patient or staff, or damage to property. Therefore, please make sure that you are fully informed about the correct method of functioning and handling of the OPERON B 710 by reading this User Manual. Attention! When adjusting the operating table, please do not reach into the field of movement of the operating table or the table top. When adjusting the back or leg plate, never reach beneath the table top frame or the area of the powered joints on either side of the central section. When adjusting the operating table, always keep the area beneath the table top clear of objects of any kind, such as e.g. the legs of a person seated at the operating table, or instrument tables; especially when lowering the table. Unforeseen adjustments to the operating table with unsecured patients can result in injury to the patient. The patient must be secured as dictated by the relevant requirements with suitable operating accessories, such as, for example, body restraint, side supports, etc.. In the case of remainig liquid in the mains socket (e.g. after cleaning the table), the liquid must be removed completely, before connecting the table to mains. The mains cable has to be connected to the table base first, bevor connecting it to the mains socket.

OPERON B 710 Service-Manual E

Attention! Observe the patient or the operating table constantly when activating one of the motorised adjustments. When fitting operating accessories, check that they are correctly fastened and tighten securely. Do not use worn or damaged accessories. Before moving the operating table, always make sure that no one has their feet in the area of the operating table foot. Never move the operating table while the mains cable is still connected to the operating table; Safety hazard due to tipping operating table! In certain situations, movement of the operating table is not permitted, or only under compliance with special safety measures, in order to prevent the possibility of the operating table tipping over. Special care must be taken to comply with the additional information marked with the warning symbol in Chapter 9, “Use of the operating table”! Objects on the floor, such as e.g. cables, hoses etc. can block the castors and thus lead to tipping of the operating table. Therefore, always keep the movement path of the operating table free of objects of any kind. Before positioning a patient on the operating table top and adjusting the patient position, the operating table must be securely locked (control via function key 3). Only patient positions described in these instructions may be used. Take particular care to comply with the guidelines in Chapter 9, “Use of the operating table”, as well as the additional information marked with the warning symbol! Please use the overview tables of chapter 9.10 “Overview of operating table top module configurations” as a guide with respect to the acceptable configurations of the operating table top and their module arrangements! When using high-frequency surgical units, defribillators, defribillator monitors, please pay attention to the instructions of the manufacture. The OR-table has to be used on a dconductive floor, when a antistatic derivation ist requested. The antistatic feature of the OR-table is dependent on the use of the matresses which are specified by the manufacture. Batteries are problem waste ! At the end of the batteries' life cycle, they must never be included with normal domestic waste, but always disposed of in accordance with the prevailing national disposal regulations.

For further information, see chapter 8.15.

6.2 Other version-specific optional features Each available product version can be supplied with the following optional features as special fittings ex works: • •

Power drive unit Wireless remote control

The product versions with a powered drive unit include an integrated driving castor in the foot of the operating table which can be controlled via an additional function key pair on the control unit (or, if necessary, on the wireless control unit) (see description in chapter 8.10.2). Those product versions that are equipped with a wireless remote control have a remote control unit with a function key arrangement that is identical to that of the wired remote control. Control of the powered functions of the operating table via the remote control unit is basically similar to control via the wired control unit (see chapter 8.4 page 13 et seq.) However, further information is necessary for the use of the operating table with the remote control; e.g. information on modalities when using several operating tables with wireless remote control in one operating area (same floor). Therefore, all necessary information and data for the use of the OPERON B 710 with the wireless remote control option are described in more details in a separate user manual, which is supplied with those operating tables that are equipped with this option.

7.3 Column control panel The additional column control panel is fixed permanently on the left hand side of the top section of the column casing. The functions of the operating table can be controlled via the column control panel in the same way as via the control unit. The symbols of the individual function keys as well as the LEDs with their respective indicator functions are reproduced identically on the column control.

è Note: The column control panel has an “emergency adjustment function” which is more than just a second control option. It has its own second electronic control for the operating table functions, which means that the column control panel is a second redundant control parallel to but also independent from the electronic control of the “regular” control unit. In case of a fault in one of the two central electronic controls, the operating table can be further operated via the respective other control (control unit /column control panel) (see also chapter 8.9.2 “Fault indicator”). 7.4 Control of powered operating table functions / Explanation of symbols To actuate a function, press the respective function key and keep it pressed down until the operating table has reached the desired position. Each powered movement of the operating table is stopped immediately as soon as the respective function key is released. è Note: • For safety reasons, the B 710 can be adjusted in height up / down function only, if the operating table is mobilised. The lateral tilt, Trendelenburg, back and leg plates functions can only be adjusted when the table is immobilised. If one of these functions is actuated when the operating table is still in moveable status (red LED next to function key 4 illuminated) the operating table is automatically immobilised in the first place. The above mentioned functions can only be controlled after the operating table has been completely immobilised (green LED next to function key 3 illuminated continuously). • When using different control possibilities, the operating table always reacts to the control unit that was first actuated. • If two functions are sactivated simultaniosly by the hand control and the foot switch, the movement will be aborted.

7.4.1 Basic functions of the operating table 1. Symbol for “OR table control OFF”. Pressing this function key switches off all control units; any motorised movement of the operating table is stopped immediately. 2. Symbol for “OR table control ON”. Pressing this function key switches on the control units. The electronic control first carries out a self-test; all available LEDs flash briefly. Then, the green LED next to this function key is lit up and signals readiness for operation. The operating table can now be adjusted using its powered functions. è Note: The operating table is provided with an automatic cutoff in order to save battery charge level, i.e. if no function key is pressed on either of the control units for longer than approx. 30 min. when the operating table is switched on, the operating table will switch off (green LED for function key 2 goes out). 3. Symbol for “Operating table immobilised”. By briefly pressing this function key, the castors of the operating table are immobilised - clearly audible sound - for operative use; in this case, the respective LED sends out a green flashing signal. As soon as the operating table is completely immobilised, the green LED illuminates permanently. è Note: This function key need not be pressed until the green LED illuminates constantly; with this function, briefly pressing is enough for the castors of the operating table to be immobilised. Alternatively, the operating table can also be immobilised by briefly pressing any of function keys 11 to 20. 4. Symbol for “Operating table mobilised” By briefly pressing this function key, the castors of the operating table are released to move / manoeuvre - clearly audible sound. As soon as the operating table is mobilised, the red LED flashes (green LED of function key 3 goes out). è Note: This button does not need to be pressed continously until the green LED illuminates. It is effectual to press the button briefly to release the castors of the OR-tables. The status of the mobilisation will be alsways be adjusted according to the illumination of the LED beside button 5 or 6. 5. Symbol for “Operating table can be moved freely”. By pressing this key, all 4 castors of the operating table are made ready to rotate freely (green LED illuminates, LED next to function key 6 goes out) when the operating table is mobilised via the function key 4, which allows for the operating table to also be moved transversely to the longitudinal axis of the operating table top.

12

OPERON B 710 Service-Manual E

6. Symbol for “Operating table can be moved in track stabilised mode”. By pressing this function key, one of the castors of the operating table is set in such a way that it is locked in the longitudinal axis position of the operating table top (green LED illuminates, LED next to function key 5 goes out); the remaining three castors can still rotate freely, which results in a track stabilised directional movement of the operating table over a longer straight distance, when the operating table is mobilised via the function key 4. è Note: • The required movement / manoeuvring characteristic of the operating table can be selected at any time via this function pair, i.e. regardless whether the operating table is mobilised or immobilised. If the operating table is mobilised via function key 4, always the movement characteristic is set which is indicated by the respective LED of the function keys 5 / 6. • The once selected “free movement” or “track stabilised” mode of the operating table is maintained until the opposite movement is consciously selected via function keys 5 or 6, i.e. even after switching off the operating table (via function key 1) and switching it on again, the manoeuvre characteristic last selected is set up again. 7. Symbol for “NORMAL patient orientation” By pressing this function key the patient's recumbent orientation is defined so that the patient's head is located above the longer end of the operating table foot (normal orientation). The green LED next to the function key illuminates, the LED of function key 8 goes out. 8. Symbol for “REVERSE patient orientation”. By pressing this function key, the patient's recumbent orientation is defined so that the patient's head is located above the shorter end of the operating table foot (reverse orientation). The green LED next to the function key illuminates, the LED of function key 7 goes out. è Note: • The function keys 7 and 8 ensure that the symbols of function keys 11 to 20 are corresponding to the desired movement direction of the operating table top, after selecting the orientation direction of the patient. • The once selected NORMAL or REVERSE orientation is maintained until the respective opposite orientation is consciously selected via function keys 7 or 8, i.e. after switching off the operating table (via function key 1) and switching it on again, the orientation last selected is set up again.

7.4.2 Function keys for operating table adjustments 9. Symbol for “Height adjustment downwards” When this function key is pressed, the entire table top moves downwards.

10. Symbol for “Height adjustment upwards”. When this function key is pressed, the entire table top moves upwards.

11. Symbol for “Lateral tilt to the left”. When this function key is pressed, the entire table top tilts to the left. The definition “to the left” refers to the direction in which the patient is lying, i.e. the table top is tilted to the left, viewed from the head end side. 12. Symbol for “Lateral tilt to the right”. When this function key is pressed, the entire table top tilts to the right. The definition “to the right” refers to the direction in which the patient is lying, i.e. the table top is tilted to the right, viewed from the head end side. 13. Symbol for “Table top into Trendelenburg position”. When this function key is pressed, the entire table top inclines with the head end down (Trendelenburg). 14. Symbol for “Table top into Reverse Trendelenburg position”. When this function key is pressed, the entire table top inclines with the foot end down.

15. Symbol for “Back plate inclined downwards”. When this function key is pressed, the entire back plate of the table top inclines downwards.

16. Symbol for “Back plate inclined upwards”. When this function key is pressed, the entire back plate of the table top inclines upwards.

17. Symbol for “Leg plate inclined downwards”. When this function key is pressed, the entire leg plate of the table top inclines downwards.

18. Symbol for “Leg plate inclined upwards”. When this function key is pressed down, the entire leg plate of the table top inclines upwards.

OPERON B 710 Service-Manual E

7.4.3 Additional functions 19. Symbol for “bend operating table top” (“FLEX”) When this function key is pressed down, the operating table top functions “Reverse Trendelenburg” and “back plate downwards” are controlled automatically in alternating sequences and a bent (or “roof top”) position of the operating table top is obtained for a flexed patient positioning. 20. Symbol for “operating table top in semi-sitting position” (“BEACH CHAIR”) When this function key is pressed down, the operating table top functions “Trendelenburg”, “back plate upwards” and “leg plate downwards” are automatically controlled in alternating sequences, which results in an operating table top position for a (semi-)sitting patient positioning. è Note: • For technical reasons, a simultaneous movement of several powered functions is not possible. Hence, by pressing function key 19 or 20, the operating table top position is adjusted by alternatively controlling the necessary individual functions several times one after the other. • For the same reason, these additional functions have to only be used starting from the horizontal position of the operating table top (0-position). If the additional functions 21 or 22 are controlled from an already adjusted operating table top position, this can possibly result in an “uncoordinated” end position, i.e. not matching the “Flex” or “Beach Chair” position.

OPERON B 710 Service-Manual E

7.4.4 Zero-position function(s) (return to level) 21. Symbol for “0-position function”. When this function key is pressed, the operating table is automatically aligned into the horizontal position in its tilt, Trendelenburg, back plate and leg plate functions (0-position). è Note: • •

•

•

16

The 0-position functions facilitate control of the OPERON B 710 towards the end of an operation, if for example a flexed patient positioning needs to be given up to enable wound closure. For complete alignment of the operating table top into a horizontal position, only function key 21 needs to be pressed. The permanently illuminated LED next to function keys 7 and 8 (patient orientation), which at the same time is also a function display (see chapter 8.5.2 “Other LED displays”) informs you about the status of the complete 0-position. When function key 21 is pressed down, the LED next to the function key 7 / 8 displays a green flashing signal, if the adjusted functions of the operating table are not all aligned into horizontal position yet. When all functions are aligned into horizontal position, the green LED illuminates permanently again, as a sign that all adjustment processes have been completed. For technical reasons, a simultaneous movement of several powered functions is not possible Hence, when horizontally aligning the operating table top, the lateral tilt is adjusted back to level first, if necessary, followed by the remaining adjusted functions in automatic alternating sequences. In addition to the complete 0-position function provided by function key 21, the OPERON B 710 also has an individual 0-position function for tilt, Trendelenburg, back plate and leg plate. This is helpful if the entire position does not need to be changed perioperatively, e.g. in the case of breast operations, if only the back section of the table top needs to be adjusted repeatedly and realigned horizontally. If e.g. the operating table was in Trendelenburg position via function key 15, by pressing function key 16, the top only moves into Reverse Trendelenburg until a horizontal position was reached. If further Reverse Trendelenburg adjustment is necessary, briefly release the function key, press it again and the function will allow further adjustment. For all other operating table top functions, the movement described above applies in the same way.

7.5 LED displays on control unit and column control panel 7.5.1 LED displays for battery capacity / power supply There are LED displays on the control unit and the column control panel that give information on the charging status of the batteries integrated into the foot of the operating table. Green LED a: Symbol for “battery capacity high / sufficient” This LED displays a green continuous light when the operating table batteries are fully charged or the overall battery capacity is still more than 90%. LED a switches to a green flashing signal when the battery capacity has dropped below 90%, but there is still a residual charging capacity of approximately 30% (or more). With a further decreased battery capacity, this LED goes out completely and the red LED c illuminates instead (see below). Yellow LED b: Symbol for “Mains operation / Charging of operating table batteries”. This LED displays a continuous yellow light when the operating table is connected to the mains supply via the mains cable.

Red LED c: Symbol for “battery capacity low / insufficient”. This LED displays a continuous red light when the capacity of the operating table battery has dropped below approx. 30% of the residual charging capacity. (The green LED a has gone out) The LED c switches to a red flashing signal when the battery charging capacity has dropped below approx. 10%. The batteries must be recharged at the end of the operation. Please see the Chapter 8.6 “Recharging the operating table batteries” for this purpose.

Note: If the control units are switched off (function key 1), the status, the OR table being connected to the mains, will be indicated by the green LED n only, which is contained in the table’s foot construction (see also following chap. 8.5.2).

7.5.2 Other LED displays Next to the function key 1, there is a red LED f that flashes when an error in the electronic control was recorded. For further information, also see chapter 8.9.2 “Fault indicator”.

Both LEDs next to function keys 7 and 8 for patient orientation simultaneously work as function display: When one of the function keys for the adjustment of the operating table top is pressed down, the green LED switches from a continuous to a flashing signal. When the function key is released, the continuous signal appears again. At the foot of the operating table, next to the mains connection socket, there is a further green LED n which always illuminates, when the operating table is connected to the mains power supply. For further information, see following chapter 8.6 “Mains operation”

7.6 Mains operation / Recharging the operating table batteries The operating table is disconnected from the mains by removing the mains cable from the mains socket. The OPERON B 710 has an integrated charging unit. In order to recharge the integrated batteries of the operating table by mains supply, the operating table is to be connected to the mains via a mains cable. The mains connection socket 7 is located on the left hand side in the foot of the operating table below the foot panelling. The primary voltage of the operating table is stated on the type plate. The secondary voltage of the operating table (internal voltage) is 24 V DC.

è Note: • The OPERON B 710 is suitable for mains / battery charging operation in the operating room, with the patient on the table. However, please take care to comply with the relevant national regulations. • Battery operation is preferable to operation by mains supply for routine use of the operating table. Damaged mains cables may not be used and have to be raplaced immediately. If the proper condition of the arrangement or assembly of the ground wire can not be guaranteed, the ORtable also has to be operated, the OR-table also has to be operated by using the internal power supply.

Recharging the operating table battery: Immobilise the operating table by pressing function key 3. Connect the operating table to the mains with the mains cable by first connecting the mains cable to the connection socket 7 of the operating table and then to a mains connection socket. Switch the operating table on (function key 2 on a control unit; if necessary, use switch 8 first) and check whether the yellow LED b is lit up. If the green LED a continuously illuminates (when the operating table is switched on), it means the batteries of the operating table are fully charged. è Note: • Fully charged batteries provide an operating table adjustment capacity for up to approx. 100 operations; dependent on the required adjustment frequency and the weight loading for the operating table. • Fully discharged batteries (less than 10% residual charging capacity) need a charging time of approx. 16 to 20 hours. • We recommend to recharge the batteries early instead of waiting for the red / red flashing signal of the LED c to appear: Regular recharging of the batteries, e.g. after the daily operation schedule, overnight or over the weekend, not only guarantees adequate battery capacity for conducting operations, but also helps to extend the service life of the batteries. • The batteries can also be charged when the operating table is switched off by pressing function key 1 or even was “completely” switched off via the switch 8. On the side of the operating table foot, in the area left next to the mains connection socket, there is a control LED n which always illuminates when the operating table is connected to the mains power supply via the mains cable. Batteries are problem waste ! At the end of the batteries' life cycle, they must never be included with normal domestic waste, but always disposed of in accordance with the prevailing national disposal regulations. 7.7 Switch for the OR table electronic control The switch 8 for the electronic control of the operating table is also located in the foot, directly next to the mains connection socket. This toggle switch 8 can also be used to switch off all functions of the operating table. Main switch 8 in upper position (“ON”), the operating table is switched on. Switch off the operating table electronic control: Put toggle switch 8 in lower position (“OFF”). è Note: • When the operating table is delivered from the factory, it is switched off at the toggle switch 8. • When the toggle switch is in the “OFF” position, the operating table cannot be switched on via the function key 2. However, the recharging of the operating table batteries is possible. • If the operating table is not going to be operated for a prolonged period of time, e.g. for several days or weeks, the batteries should be fully charged first and then the operating table switched off at this switch.

7.8. Fuses for mains charging transformer The primary fuses for the mains transformer are located in screw-on holders directly below the mains connection socket 7. To exchange the primary fuses, first disconnect the operating table from the mains! Open the screw-on holder(s) of the fuse(s) by using a flat-bladed screwdriver and remove the fuses from the holder. In the case of necessary exchange, only use fuses according to the voltage indicated below. Product version OT 160-10-04 (220/230/240 V AC) OT 160-10-14 (100/120/127 V AC) OT 160-10-75 (100/120/127 V AC)

7.9 Safety functions The OPERON B 710 is equipped with different safety characteristics that increase the safety of the patient and user in routine operation of the operating table. Further safety functions are described hereafter beside the following characteristics already mentioned in the function descriptions: “Override” through the control panel at the colums 15, “switch off function” via switch 8 and the various LED displays. 7.9.1 Anti-collision function for powered adjustments The OPERON B 710 is equipped to a certain extent with an anticollision function in its powered adjustments, i.e. before damage can occur, like e.g. between the leg plate adjusted in downward position and the foot panelling, the relevant movement is automatically stopped (while function key activated), even though the maximum adjustment technically possible has not been reached yet. è Note: In routine operation, whereby very extreme adjustment levels of the operating table top are only very seldom used, the anticollision function will accordingly be activated very seldom or not at all. For technical reasons, the anticollision function can only influence the “technical system operating table” itself. The operating table or its anticollision function can not register “foreign” objects automatically, i.e. any objects or also persons which may happen to be situated in the field of movement of the operating table! Consequently, a powered adjustment which would lead to a collision with an object possibly located below the operating table top (e.g. instrument table among other things) can not be prevented by the anticollision function.
