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.
Page 7

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.
Page 8

Operation: Advanced Functions
Hold Function
Press the HOLD button once.
Allow the patient to stand on 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

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

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.

should be used no closer to
any part of the scale 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 √P80MHz to 800 MHz
d = 2,3 √P800MHz to 2,5
GHz
Where P is the maximum
output power rating of the
transmitter in watts (w)
according to the transmitter
manufacturer and dis the
recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site
survey, should be less than
the compliance level in each
frequency range.
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 scale is used exceeds the application RF compliance level above, the scale should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the scale.
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-100.
This scale is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the scale can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters)
and the scale 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 meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where p is
the maximum output rating of the transmitter in watts (w) according to the transmitter manufacturer.
NOTE1) At 80 MHz and 800 MHz, the separation distance for the high 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.

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.
