Assembly and set up The ADE chair scale is already been delivered in a fully assembled condition. Please insure that your scale is being placed vibration free at a dry place. Alignment of the scale 1) Place the chair scale on a plain, dry and level surface before the weighing of patients. 3) The air bubble in the spirit level should be right in the centre of the circle 4) Please ensure that the scale has no other contact to the floor than by the four wheels after the patient has been seated onto the chair scale.
Power supply Power is supplied either by the rechargeable battery in the display unit or by the mains power via the supplied power unit. The imprinted voltage value at the mains adapter must match the local mains voltage. After checking same connect the mains cable to the indicator and to a socket. Note: The wall socket must be located near to the unit and be easily accessible. Please use only the mains adapter supplied by ADE. The mains adapter is charging the battery pack at the same time. When the battery is being charged for the first time a sufficient charging period of approx. 24 hours is necessary to achieve a full battery load. In case the scale is being used with batteries only and the display indicates – Lo, the battery should be recharged with the ADE mains adapter. After the first charging period the battery need 12-16 hours. The battery should be charged while the scale is switched off. Upon completion of the charging period switch the scale on again to check the battery status. In case Lo- still appears on the display inform your service partner.
Replacing the rechargeable batteries The battery compartment is located at the front of the unit. 1) Open the battery compartment. 2) Remove the battery cable and the corresponding connector carefully from the housing. Disconnect the battery pack. Connect the wires/plug (red to red, black to black) with the new battery pack and insert same into the housing. 3) Close the battery compartment. Only use original rechargeable batteries and charger units from ADE. The warranty does not cover any damage caused by using other types of batteries or charger units.
Tips for handling the batteries The life of a battery depends essentially on the load, frequency of use, temperatures, settings and the accessories used. – New batteries or batteries that have been stored for long periods require a longer charging period. – Charge the batteries at room temperature. – Store the batteries empty (uncharged) in a cool, dark and dry place. – Never expose the batteries to temperatures below -10°C (14°F) or above 45°C (113°F). – Over the course of time, batteries lose their charging capacity and require a recharging period. If the battery performance drops considerably, then it is time to replace the battery. – New batteries are supplied only in partial charged condition. Some batteries only achieve their full capacity after several complete charge and discharge cycles. – When disposing of disused batteries, observe the valid legal and municipal regulations. Never dispose of batteries in fire as they can leak or explode! 4

Positioning of patient Please ensure for security reasons that all brakes at the wheels are being locked. Move the armrest and footrest in an upright position before the patient is being moved onto the scale. Fold down the armrest and footrest and place the feet of the patient upon the footrest.
After finishing the weighing procedure please make sure, that arm- and foodrest are being moved again into the upright position before patient stand up again. Armrest and footrest are not to be used as helping device for getting up from the chair! They are to be understood as supporting device for arms and legs only in order to allow an accurate weighing procedure!

Weighing Press the ON key for at least 3 seconds to turn the scales on. An automatic function test is carried out after being switched on. This test is completed when the display shows zero. The scale is now ready for the weighing procedure.
Resetting the scales back to zero Wait until the standstill status indicator (14) appears. By pressing the ZERO key (8), measuring inaccuracies after switching on the scale are being compensated. The zero key restarts the scale. The status indicator (6) appears when the scale is being resetted.
Tare function The TARE key (9) is used when the patient is being weighed with other items (e.g. clothing, shoes or other items) which should be ignored by the scale. To do this, weigh these items first. After the weight is displayed, press the TARE key (9) to reset the display back to zero. The display changes to net mode (NET status indicator (5) is on). The weight of the previously weighed and saved items is ignored when the patients’ weight is displayed. Enter the tare button again to get back to the normal weighing mode and remove any load from the platform. Entering manually tare - values: Enter the appropriate tare value just by using the key pad under normal weighing mode. If the tare value has been entered correctly, the value will be stored. Press the ENTER key (or TARE). The ADE-display is now ready for weighing and changes to net mode [NET status indicator (5) is on]. Enter the tare button again to leave this mode. The manual tare value must be >0, the maximum value is limited by the weighing range. Preset tara Press and hold the PRESET TARE key (10) [approx. 3 sec.], PRO PT X appears on the display. Select the memory location 1-10. Now enter the TARE VALUE which you would like to be ignored by the scale and confirm same with ENTER. Enter the tare button again to leave this mode. Restore the preset tara value: Press the PRESET TARE key (10). "Pt x" appears on the display. Enter a number from 0-9 (memory location for the tare value). If no number is entered within five seconds, the unit will turn back to weighing mode. After entering the number, the ADE-MAK accesses the preset tare value, shows it for five seconds on the display and then changes to net mode. The accessed tare value is accepted at the same time. Enter the tare button again to leave this mode. Displaying the gross weight, net weight and tare value: Press the "0" key to change between displays for tare, gross weight (NET status indicator (5) off) and net weight (NET status indicator (5) on). If a tare value is saved, the net weight shown corresponds to the gross weight minus the tare value. If there is no tare value saved, the display remains in gross mode. The tare value flashes briefly, then after a second the display changes to gross mode.
Hold function Use the HOLD key to hold the display if there are weight fluctuations which e.g. are caused by patient movements on the scales. You could also use this function if you like to hold the results at the display after the weight/load has been removed from the scale. To do this, the scales must be at standstill, e.g. the standstill status indicator (14) is on (depending on the setting it is not always necessary for the scales to be at standstill). The Hold status indicator (15) is on. Deactivate the HOLD function by pressing the key again.

Determining the Body Mass Index (BMI) The BMI figure is a index which displays the ratio between height and weight. body weight BMI= (height)² To determine this value you need the height of the person. Best way to get the height is of course to use an ADE height measuring rod; model MZ10023. Start the scale and weigh the person. Then press the BMI key (11) to start BMI mode. The last value entered appears on the display. Use the numerical key pad to enter a new value for the height (in cm) or retain the value which is already displayed. Confirm the value entered with the ENTER key or delete same by using the CLEAR key. After the entry has been confirmed by the ENTER key, the BMI value will be calculated using the weight on the scales. The display changes between weight value and BMI value "b xx.x" (every two seconds) for a period of 3 minutes. Press the BMI key (11) to cancel befoe this time has expired.
