description of the equipment

2 DESCRIPTION OF THE EQUIPMENT The equipment you have purchased features a state-of-the-art color CCD camera which was especially designed for use with endoscopic applications. In combination with the built-in high-intensity xenon illumination, the device offers the user a compact unit for optimal image quality in nearly every endoscopic discipline. CCD camera Full digital signal processing ensures true color reproduction. The camera consists of a control unit and a complete watertight camera head. Located at the front of the ergonomically shaped camera head, there is a CMount-Thread adaptation, where you can connect usual lenses, vario-focus TVcouplers or other couplers to connect the endoscope. Located inside the camera head is the CCD-chip, which takes the image and converts it into electric signals. These signals are conducted through the camera cable to the control unit. Inside the control unit, the image data is processed and is provided either as Standard-FBAS-Signal (BNC-connector, VHS-standard) or as Hosiden-Signal (Y/Csignal, Mini-DIN-connector, S-VHS-standard) on the rear panel for displaying on the monitor and/or other devices, such as videoprinter, videorecorder, etc.). The image-brightness is controlled by an electronic shutter, which is working with a shutter-cycle at minimum of 1/2.000.000 sec., so that even when the image is totally irradiated a well-balanced video picture is delivered to the monitor. If the image is extremely dark illuminated, the shutter cycle becomes so high, that it is impossible to display a flicker-free picture. In this case, the videosignal is emphasized electronically by max. +30dB. This electronic emphasis is called AGC (Automatic Gain Control). It has to be taken into account that the noise on the picture is increased when the AGC is working. xenon lightsource The built-in xenon illumination features a high-intensity xenon lamp, which is installed in a reflector. The lamp designed is optimized for endoscopic applications. The color temperature equals daylight quality with a color temperature of 5.700 K.

the equipment trolley by means of a grounding cable. • If the camera is used in conjunction with HF-coagulators, it is imperative that you use insulated endoscopes, couplers and lightguides. (breakdown voltage at minimum 4.5 kV). • The equipment may only be connected to devices which also comply to the demands of the IEC 601-1. • Never directly observe the lightbeam, the instrument side of the lightguide, or the lightbeam coming from the endoscope.

This could severely damage the

retina of the eye. • Any modifications and changes to the device may only be carried out by the manufacturer of the equipment. The instructions made in this operation manual have to be followed, otherwise we refuse any liability. • In order to protect the lightguide and the patient, there is a heat reflecting filter installed which reflects the heat radiation produced by the Xenon-lamp. Always check before switching on the equipment and especially after every transport of the equipment whether this filter is unbroken. Otherwise, the heat radiation is emitted to the patient at the distal end of the attached endoscope and burning of the skin surface can occur. • Naturally, the built-in xenon bulb produces apart from the light output a certain amount of heat, which is carried off by fan cooling. In order to ensure that the heat flow is not hindered, the following precautions must be observed. Otherwise, the lightsource will be seriously damaged and there is a risk of fire hazard ! • Never cover the louver type slots ! • The cooling is most efficient when the lightsource is placed on a table where the air flow at the rearpanel is not hindered in any way. • If it is unavoidable that the lightsource has to be placed in an equipment trolley, make sure that the trolley allows sufficient air flow at the rearpanel. • Never place the lightsource in a partition of the equipment trolley which is closed at the rear ! • We strictly refuse any liability for damages which result from inadequately placement of the lightsource. • The equipment is designed for indoor use.

position of control elements

connector for camera cable This connector is used for attachment of the plug of the camera cable. The plug can only be plugged in a certain position. This is achieved by a small nose on the top of the plug. The red mark on the 14-pin-plug must correspond with the red mark on the socket to install the plug. The plug fastens automatically when completely plugged in. To unfasten the plug; grip the knurled part of the plug and pull the plug out of the socket. push-button “WHITEBALANCE” The WHITEBALANCE is done by pressing the corresponding push button f. Therefore, aim the camera head on a homogeneously illuminated white sheet of paper or a well-illuminated multi-color object. Simultaneously, press the push button once. The button then will flash until the WHITEBALANCE is finished. The current WHITEBALANCE is stored in memory and is also saved, when the camera is switched off. Take notice, that the paper-sheet or the multi-color object is not irradiated, that means, e.g. that the grain-structure of the paper is visible on the monitor. If WHITEBALANCE is done correctly, a natural color reproduction is guaranteed. push-button “WINDOW” The WINDOW-function is turned on and off by pressing the corresponding push button g. The WINDOW-function carries out a light measurement that only affects a central window of the picture. That means, that in contrast to standard measurement, where the average brightness is integrated over the entire picture size, only a center part of the image is taken to evaluate the average brightness, outer margins are disregarded. To activate the WINDOW-function, push the corresponding button. If the WINDOW-function is activated, a yellow light inside the push button is illuminated and a light-gray rectangle appears on the monitor for a short time. That represents the area that is taken for brightness evaluation. If the object to be regarded is in the center of the picture, you should activate the WINDOW-function. The object itself is displayed correctly illuminated

video output terminals You can attach external output-devices such as monitor, videorecorder or videoprinter to the VIDEO-OUT connectors. The videosignal is provided in two different standards. 1. The BNC-terminal k provides the videosignal as VBAS-signal (compostsignal, VHS-standard). 2. The 4-pin-Y/C-terminal j provides the videosignal as Hosiden-signal (separate conductors for chroma- and luminance-signal, S-VHS-standard). Both video outputs are available simultaneously so that both standards can be used at one time. It is preferred to use the Y/C-signal than VBS-signal if possible. You will achieve a much better image quality in contrast to VHS-standard.

connecting the equipment

5 CONNECTING THE EQUIPMENT

ALWAYS INSTALL ALL CONNECTIONS BEFORE SWITCHING ON THE EQUIPMENT ! CONNECT THE POWER SUPPLY CORD ! Use the delivered protectively grounded power supply cord to connect the control unit to a grounded wall socket. Please check whether the current voltage selection matches your local voltage. CONNECT THE CAMERA CABLE ! Install the plug of the camera cable in the corresponding socket on the frontpanel as described above. You can connect all lenses and endoscope couplers to the camera head, which are equipped with a C-Mount-Thread or CS-Mount-Thread. When you use objectives with CS-Mount-Thread, an additional intermediate ring is necessary. Your dealer supplies various lenses and couplers for your special requirements. CONNECT THE EXTERNAL OUTPUT DEVICES ! As described before, there are several standards of videosignals available on the rearpanel. Here you can connect external output devices such as monitor, videorecorder, videoprinter, etc. If you are using standard VBS-signal (BNC-terminal), please always apply high-quality 75Ω-coaxial cables. If the external output device has a switchable 75Ω-termination resistor, you should switch this on. If you connect several devices in a row, only the last device in the line needs to be terminated by the termination resistor. If the external device does not provide such a termination resistor, you should connect the coaxial cable via a T-connection-adapter. The open end of the T-connection adapter is then terminated with the 75Ω-resistor. We recommend the use of the delivered S-VHS-cable.

operation of the equipment

6 OPERATING THE EQUIPMENT 6.1 preparing for operation After having installed all connections, the camera can be set to work. Switch on the control unit using the main switch on the frontpanel c. The green lamp inside the switch lights up. If all other devices are switched on, a picture appears on the monitor. The lamp ignites after 5 sec. and will reach it’s full intensity within a few seconds. Set a median intensity of illumination using the corresponding push button h and i. Now proceed with the WHITEBALANCE. To achieve WHITEBALANCE aim the camera head towards an illuminated white sheet of paper and simultaneously press the push-button once and wait until the button stops flashing. Take notice that the paper-sheet is not irradiated, that means e.g. that the grain-structure of the paper is visible on the monitor. Now the regarded image is displayed correctly illuminated and true-colored on the monitor. value.)

7 SERVICE AND MAINTENANCE 7.1 cleansing and disinfection before initiating of cleansing:

PULL OUT THE MAIN PLUG All parts of the outer surfaces of the unit (housing, front- and rearpanel) are totally insensitive to all the usual cleaning and disinfecting materials, so that you can use any of these without limitation. In order to avoid scratches on the surfaces and be able to control the amount of liquid, apply liquids using a soft cloth or a soft blotting paper. Cleaning or disinfecting liquids should not be sprayed directly onto the housing and then spread. With flammable liquids like alcohol, you should apply with a cloth. Do not let any liquid get into the equipment. After cleaning with flammable liquids, leave the equipment to dry for one hour before it is switched on again. There is danger for example that an alcohol-air explosive mixture could form after cleansing! For medical applications, the camera is delivered with a watertight camera cable and camera head. This cable can be immersed into a disinfecting liquid.

The camera cable must not be autoclaved ! Before immersing the camera cable, you have to screw the sealing-cap onto the plug. Take care of correct position of the thick red sealing.

7.2 Exchanging the main fuses e main fuses are located on the rearpanel of the control unit, right above the main terminal device in a small drawer. you want to change the voltage settings, you have change the fuses to the corresponding rating. 1. Pull out the main plug ! 2. Loosen the drawer by unfastening the two clamps located to the left and to the right of the drawer with a peaked tool and pull out the drawer.

service and maintenance 3. Take out the two fuses. 4. Check the fuses. A blown fuse is indicated by the blackened glass cylinder or the visibly melted fuse conductor. If necessary, check the fuse with an ohmmeter. 5. If you need to change the voltage selection, take out the white insert inside the fuse drawer, turn it around 180° and re-insert it. Now the voltage selector shows another voltage. 6. Install the corresponding fuses. You will find the right fuse ratings in chapter 8. They are printed as well on the rearpanel. 7. Re-install the fuse-drawer. 8. Switch on the equipment.. If you have exchanged a defective fuse against a new one and the fuse blows again; the unit has an error. In this case, you must return the device to your dealer for testing and repair.

7.3 Exchanging the lamp The only part subject to wastage in the equipment is the lamp. The manufacturer of this lamp estimates the minimum life expectancy as 500 hours. After that, the quoted light wattage reduces drastically and there may be difficulties in igniting. In order to secure safe operation of the equipment, the lamp should be changed after the expire of the operation time.

Since the lamp used is a high pressure Xenon-lamp, whose small combustion chamber is high pressure, the bulb can explode if you handle it incorrectly (danger of glass splinters)! The lamp may only be changed by qualified personnel, and following the prescribed safety precautions. Therefore, send for the qualified person when it is necessary to replace the lamp. 1. If the lightsource was under operation right before lamp change, the lamp is still very hot. Allow the lamp to cool down before handling. 2. When handling the lamp, protective goggles and gloves which also protect the arteries must be worn! 3. The lamp must be stored in the original packing, when outside the equipment, never left lying around! 4. Never interfere with the contacts, the electrodes, or the electrode connections, or exert pressure or stronger action on other parts of the lamp!

page 15

user manual

service and maintenance 5. Self disposal: Wrap old lamps in a thick cloth and crush it into small pieces with a hammer on a firm base. The gas in the lamp (Xenon) is completely non-poisonous. 6. Never throw used, undestroyed lamps into the rubbish: Dangerous for playing children or other innocent parties who may not be aware of the danger!

If you observe the safety precautions, there is absolutely no danger and you can proceed to easily change the lamp in the following manner: • Pull out the main plug ! • Loosen the 4 screws of the cover located on the left and the right side of the unit. Take off the cover and place it beside the unit. • Attention: If the machine has been operating shortly beforehand, the lamp could be very hot. • All remaining currents in the electronics will be, in a few seconds after switching off the equipment, completely safely discharged. There is no danger in handling the equipment here. • Disconnect lamp connector plug. Push the two clamps of the plug. Open the knurled head screw of the lamp holder, lift up the lamp guard and pull out the lamp. • Insert a new lamp and close the lamp guard again. Fasten the lamp guard with the knurled head screw. For correct positioning of the lamp, refer to fig. 3. • The lamp is thus automatically and correctly adjusted. Re-connect the plug. You cannot mix up the connectors due to its nonsymmetric design.

7.4 Further maintenance in conjunction with lamp change After 500 hours of operation, dust may have been sucked through the fan blades into the equipment due to the conditions in the environment. This dust should be removed from the equipment with a vacuum cleaner using a small nozzle attachment. Dust can sometimes cling quite firmly to the fan blades. This should then be cleaned with a cloth and a little alcohol/spirits. Likewise dust settles on the heat protective filter and should also be cleaned with a soft cloth or blotting paper and pure alcohol or spirits. Concerning use of flammable liquids, pay attention to safety precautions in chapter 7.1 After that: Re-install the cover and fasten it with the 4 screws. After the drying time has expired, switch on the lightsource and check if it is working.
