Tips or handling the batteries
The life of a battery depends essentially on the load, frequency of use, temperatures, settings and the acces-
sories being used
– New batteries or batteries that have been stored for long periods require a longer charging period
– Charge the batteries at room temperature
– Never expose the batteries to temperatures below -10°C (14°F) or above 45°C (113°F)
– Rechargeable batteries lose their charging capacity over the time and require a longer charging period
the older they are If the battery performance drops considerably, then it is time to replace the battery
– New batteries are supplied in partial charged condition Batteries achieve their full capacity after several
complete charge and discharge cycles
– Do not throw old rechargeable batteries into the domestic waste Ensure that the valid legal and municipal
regulations of your country are being followed
– Never dispose of batteries in fire as they can leak or explode

Operation
Modes o operation
 Weighing mode
The "weighing mode" is of course the standard mode of your scale After initial configuration and sealing (by
attaching a calibration sticker to the back of the unit), the ADE-scale can only be operated in this mode
 Setting mode
Date, time and consecutive numbers for print commands are being set in this mode To start setting mode,
hold the GROSS/NET key pressed until TIME appears on the display
 Con iguration mode (set-up mode)
The values for different parameters including the calibration could be set in the configuration mode This func-
tion is reserved for authorized service personnel only

There are different diagnostic functions for the ADE-MAK in test mode This is reserved for service personnel
only
Manipulations to test and con iguration modes can revoke the calibration status and will result
in loss o warranty!
Weighing
Press the ON key for at least 3 seconds to turn the scales on An automatic function test will be conducted
afterwards The test is done 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 entering 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
The modell M500020-D is being supplied with a seat The seat is designed to take a weight upto
100kg Take care that the patient, who uses this seat is weighing not more than max 100kgs

Tare unction
The TARE key (9) is used when the patient is being weighed with other items (e g wheelchairs, clothing,
shoes or other items) which should be ignored by the scale To do this, weigh these items first 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) and shows zero
Entering manually tare - values:
The user is able to insert manually the gross weight, which is for example mentioned at the identification plate
of the wheelchair Enter the appropriate tare value just by using the key pad under normal weighing mode
The value will be stored after use of 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 to leave this mode
Preset tara
Press and hold the PRESET TARE key (10) for approx 3 seconds 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 The value is displayed as a negative figure and will be deducted when a load is
being placed on the scale Enter the on/off, zero – button (8) to leave this mode
Restore the preset 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 new number will be inserted to change the already displayed value within five sec-
onds, the unit will turn back to weighing mode and displays the last stored value as negative figure as above
Enter the on/off, zero – button (8) to leave this mode
Displaying the gross weight, net weight and tare value:
Press the "0" key to change between the net weight (gross weight minus the tared value) and the gross
weight
Hold unction
The determined weight could be continued being displayed even when the load has already been removed
That enables taking care of the patient first before reading the results
To use the hold function the scale must be at standstill The standstill status indicator  (14) is on and
Hold appears at the digital display 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
BMI=
body weight
(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 dis-
play 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 before this time has expired
