side of the indicator.
Installing & Replacing the Battery Pack
1. Take out the battery housing.
2. The rechargeable battery pack will slide into, or out of, the housing.
3. Check that the housing pin is connecting to the right point inside the indicator.
4. Place the housing back in the back of the indicator, and close the battery housing cover.
Optional battery holder (to fit AA
sized batteries – contact your
dealer)

Switching on the Scale
Press the ON/OFF button firmly.
The scale will first test all of the display segments.
The scale will now show its current software version number.
The scale will now go into weighing mode and should show 0.0kg on the
display.
Switching off the Scale
Press the ON/OFF button when the scale is turned on. The scale will now
power down.

Setting the Scale to Zero
If for any reason the scale shows a reading other than 0.0kg it can be
reset to zero.
Press the ZERO key once.
The scale will return to 0.0kg.
Hold Function
Press the HOLD button once.
Allow the patient to be wheeled onto the scale.
After a few seconds the scale will lock on the person’s
weight. When the patient leaves the scale, the weight will
remain on the display.
Press HOLD again to disable the Hold function and return
the scale to 0.0kg.

Page 9 of 18
Setting Auto Hold Function (Optional)
The display will have a flashing triangle mark under the HOLD button
once the scale is turned on.
Allow the patient to be wheeled onto the scale. The scale will
automatically lock on the patient’s weight to complete the hold function.
The triangle mark remains on the display during this period.
When the patient leaves the scale and the scale returns to 0.0kg., the
triangle mark will begin to flash again.
Body Mass Index (BMI) Function
In normal mode, press the BMI key to enter into BMI mode.
The display will show the last height entered and the extreme left
digit will flash. Enter the height by using the numeric keys. Press the
ZERO key to confirm the height. (NB: There will always be an active
flashing digit in the height display, unless HOLD is pressed).
Weigh the patient as normal. The display will show the weight, height
and BMI value. At this time, the weight and height can be freely
changed, and the BMI value will be automatically calculated
according to the changed weight and height.
Press the BMI key to return to normal weighing mode.

Page 10 of 18
Tare and Pre-Set Tare Functions
Press the TARE key for three seconds to enter Preset Tare setting mode.
The display will show the last preset tare entered and the extreme left digit will
flash.
Enter the preset tare value by using the numeric keys, then press the TARE
key again to confirm the value.
Press the ZERO key to return to normal weighing mode.
To use the Tare function, add the item you wish to tare off to the scale, and
press the TARE key. The display will show zero, and then a minus number
when the item is removed from the scale.

Portable and mobile RF communications equipment
should be used no closer to any part of the device
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance:
d = 1,2 √P
d = 1,2 √P 80MHz to 800 MHz
d = 2,3 √P 800MHz to 2,5 GHz
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in metres (m).
Field strengths from fixed RF transmitters, as determined
by an electromagnetic site surveya, should be less than the
compliance level in each frequency rangeb.
Interference may occur in the vicinity of equipment marked
with the following symbol:
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur
radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distance between portable and mobile RF communications equipment and the M-615 Wheelchair Scale
The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the
user of the device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the device as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be
estimated using the equation applicable to the frequency of the transmitter, where p is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer.

Error Messages
Low Battery
The scale’s alkaline AA type batteries are flat; please replace
the batteries.
Overload
This indicates that the scale’s load sensor(s) have been
overloaded. Reduce the loading and retry.
Counting Error
1. The signal from the load cells is too high. Please
remove any weight from the scale and try to power
on again. If the scale continues to show the error
message, it indicates a fault with the electronics or
wiring.
2. The signal from the load cells is too low. Please
remove any weight from the scale and try again. If
the scale continues to show the error message, it
indicates a fault with the electronics or wiring.
High/Low Zero Count
1. The scale is above its zero range. Please remove
any weight from the scale and power on again. If
the scale continues to show the error message, it
indicates a fault with the electronics.
2. The scale is below its zero range. Check there is
nothing jammed underneath the scale and power
on again. If the scale continues to show the error
message, it indicates a fault with the electronics.
EEPROM Error
This indicates there is a fault with the scale’s software and is
normally caused by a fault with the load cell or wiring. Contact
your local service representative.
