Power Supply & Low Battery
The indicator uses power from 6x AA batteries, or can be powered from the mains via the adaptor.
Make sure the batteries are installed in the battery box of the indicator. Alternatively, plug the adaptor (12V 1A) into the port on
the side of the scale.
Installing Batteries
Remove the battery cover.
Remove the battery case and insert batteries, ensuring they are
properly installed.
Install the battery housing.
Refit the battery cover.
Switching on the Scale
Press the ON/ZERO/OFF button firmly.
When the scale shows 0.0 on the display you are ready to
start weighing.

Page 6 of 15
Switching off the Scale
Hold the ON/ZERO/OFF button for three seconds when the
scale is turned on. The scale will power down.
Setting the Scale to Zero
If the display shows a reading other than 0.0 when nothing is
on the scale, it can be reset to zero.
Press ON/ZERO/OFF once.
The scale will return to 0.0.

Page 7 of 15
Hold Function
Press the HOLD/BMI button once, either whilst the patient is
stood on the scale or before they step 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/BMI again to disable the Hold function and
return the scale to 0.0.
Note: If the weight reading remains on the display for more than five minutes, the Hold
function will automatically disable and the display will return to 0.0. If another patient steps on the scale whilst a held weight
reading is being displayed, the Hold function will be disabled.

Body Mass Index (BMI) Function
The patient should first stand on the scale.
Hold down the HOLD/BMI button to enter BMI mode.
The scale will enter height setting mode and the
extreme left digit will flash.
Enter the height by using the TARE/BSA button to
decrease the value and HOLD/BMI button to increase
the value. To move to the next digit, press SEND.
To confirm the height hold down the ON/ZERO/OFF
button, after a few seconds the display will alternate
between weight, height and BMI.
To exit BMI mode and return to normal weighing mode,
hold down the HOLD/BMI button.

Body Surface Area (BSA)
After calculating BMI, you can then calculate BSA. After going
through the first four steps on the previous page steps to
calculate BMI, press TARE/BSA and Body Surface Area will
be displayed.
Tare Function
Place the item/s you wish to deduct from the reading (such as
a pair of shoes) on the scale and press TARE/BSA.
Remove the item/s, and the scale will show a minus reading.
Weigh the patient as normal and the negative weight reading
will be deducted from the total weight.

Assembling the Column (M-165 only)
Assembling the M-165’s column should ideally be carried out by two people.
Holding both the column and the base, ensuring all wiring is tucked inside the column housing, turn the scale over so that the
column can be screwed to the base from the underside of the base.
Use the four screws provided, screwing them carefully into the four holes as shown in the drawing.
Before Use
1) Place the scale on a firm and level surface
2) Unwind the levelling feet until they make contact with the ground.
3) Ensure that all four of the levelling feet and the wheels are firmly on the ground and that the spirit level bubble is
located in the center as shown below:

Attaching the Height Measure (M-165 only)
The M-165 can be purchased with a height measure. If you did not purchase your M-160 with a height measure, it is also
available separately (model HM-201M).
Using the four M5*0.8*9 screws provided, mount the two
brackets onto the column of the M-165.
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.
For M-165 spare parts, call Marsden on 01709 364296.

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 M-165 is used exceeds the applicable RF compliance level above,
the M-165 should be observed to verify normal operation. If abnormal performance is observed, additional measures my be
necessary, such as re-orienting or relocating the M-165.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be les than 3 V/m.
Recommended separation distance between portable and mobile RF communications equipment.
The M-165 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the M-165 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the M-165 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.
