Operation: Basic Functions
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 8

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 9

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 10

Body Mass Index (BMI) Function
In normal mode, press the BMI button 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 ZERO 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 BMI to return to normal weighing
mode.
*If the scale is fitted with an automatic
height measure, the display will show the
height accordingly when the cursor is
raised or lowered.
Page 11

Tare and Preset Tare Functions
Press TARE for three seconds to enter
Preset Tare setting mode. When the cursor
points to Pre Tare on the display press
TARE once more. The display will show the
last preset tare value entered.
The left digit on the display will flash. Enter
the preset tare value by using the numeric
keys, then press TARE again to confirm the
value.
The display will now show the figure you
entered deducted from 0.0kg. The scale is
now ready to use.
To use the Tare function, add the item you
wish to tare off to the scale, and press
TARE. The display will show zero, and then
a minus number when the item is removed
from the scale.

mount the two brackets onto the column of
the M-110.
Using the four M5*0.8*25 screws provided,
screw the black blocks onto the mounting
brackets.
Using the two M6*1.0*10 screws provided,
screw the HM-201M to the black blocks.
To measure a person’s height, retract the
height rod and position the head stop
accordingly.

Recommended separation distance between portable and mobile RF communications equipment
and the MEDICAL SCALE
The MEDICAL SCALE M-110 is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the MEDICAL SCALE M-110
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the MEDICAL SCALE M-110
as recommended below, according to the maximum output power of the communications
equipment.
