ENVIROMENTAL
All batteries contain toxic compounds; disposal of batteries
should be delegated to a competent organisation, complying with
the deposit of Poisonous Waste Regulation 1972.
Please do not incinerate batteries.
The optimum operating temperature for the scale is 5℃to +35
℃; although it will operate at higher and lower temperatures the
scales battery life will be adversely effected.
CLEANING
We would recommend using alcohol based wipes or similar
when cleaning the scales.
Please do not use large amounts of water when cleaning the
scales as this will cause damage to the scales electronics, you
should also refrain from using corrosive liquids or high pressure
washers.
Always disconnect the scales from the mains power supply
before cleaning.
MAINTENANCE
The scale does not require any routine maintenance. However,
we recommend checking the scale’s accuracy at regular intervals.
The regularity of these checks is dependent on the level of use
and the state of the scale. If any inaccuracies occur, please
contact your local dealer or CHARDER MEDICAL service partner.
WEIGHING OPERATION
Before reading detailed instructions on how to use all the weighing
functions that are built into your scale, please read the following

4
important guidelines:
Always be sure that the display shows `Zero` before use, if it does
not then please press the ZERO key.
The device is designed to detect when a stable weight is achieved,
the indicator will `bleep` twice to indicate a stable weight value, your
reading should be taken at this point.
WARRANTY-LIABILITY
If a fault or defect is present on receipt of the unit which is within
CHARDER MEDICAL’s scope of responsibility, CHARDER shall
have the right to either repair the fault or supply a replacement unit.
Replaced parts shall be the property of CHARDER. Should the fault
repairs or replacement delivery not be successful, the statutory
provisions shall be valid. The period of warranty shall be two years,
beginning on the date of purchase. Please retain your receipt as
proof of purchase. Should your scale require servicing, please
contact your dealer or CHARDER MEDICAL Customer Service.
No responsibility shall be accepted for damage caused through
any of the following reasons: Unsuitable or improper storage or use,
incorrect installation or commissioning by the owner or third parties,
natural wear, changes or modifications, incorrect or negligent
handling, overuse, chemical, electrochemical or electrical
interference or humidity, unless this is attributable to negligence on
the part of CHARDER MEDICAL.
If operating, climatic or any other influences lead to a major
change in conditions or material quality, the treaty for perfect unit
functioning shall be rendered null and void. If CHARDER provides
and individual warranty, this means that the unit supplied will be free
of faults for the length of the warranty period.

Recommended separation distance between portable and mobile RF
communications equipment and the MEDICAL SCALE
The MEDICAL SCALE MS3910 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer
or the user of the MEDICAL SCALE MS3910 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the MEDICAL SCALE
MS3910 as recommended below, according to the maximum output power of
the communications equipment.

USING SCALE
Switch on the scale using key. The diagnostic scale self-
check is performed and the software version is displayed.
The „0,00 kg” weight displays on the screen, now the scale is
ready for weighing.
Note: If „0,00 kg” won’t display on the screen, press key to
zero the scale, can be used any time to zero the scale.

18
Place a person in the middle of the scale. Wait until the scale
stabilizes and stable sign (ο) shows on the screen
Direction:
If a person is heavier than the scale capacity, the display will show
the „Err” prompt (= overload).
USING HOLD FUNCTION
MS 3910 is provided with the integrated hold function to determine
the average weight. It enables people to be weighed accurately
although they are not still on the scale platform.
Note: Determining average weight is not possible incase of big fluctuation
between weight.
Switch ‘ON’ the scale using [ON/OFF] key. The diagnostic self-
check will be performed and after that „0.0 kg” will display on
the screen with ‘stable’ and ‘zero sign’.
Move the object/ person on the scale platform..
Press the [HOLD] key. The ‘HOLD’ will display on the screen
with blinking triangle and after few seconds the average of
fluctuating weight will display on the screen and will lock on the
display.
To release the locked weight on display simply press the
[HOLD] key again and the display will return to normal mode
automatically.
[HOLD] key function can be activated before or after putting the
weight on the tread platform. But in case of weighing unstable
person it is recommended to press [HOLD] key after the person
moves on the tread platform.

19
USING BMI FEATURE
1. In normal mode, press BMI key to enter into BMI mode.
2. The display will show last height and the extreme left digit of
figure will blink.
3. Enter the height using (0~9) number keys. (ex:170cm)
4. Proceed to weigh as normal. The instrument will show the
weight, height, and BMI value.
5. At this stage, the weight and height can be changed, and the
MS 3910 will automatically calculate the BMI value according to
the changed weight and height.
6. HOLD feature can also be used if the weight is unstable.
7. Press BMI button to return normal weighing mode.
Body Mass Index Categories
Classification of weight for adults over 18 years on the basis of Body
Mass Index according to WHO, 2000 EK IV and WHO 2004 (WHO -
World Health Organization).
