PREFACE
Thank you for choosing CHARDER MEDICAL product. All features
of this product were designed to state of the art and are optimized
for simple and straightforward use. If you have any queries or
experience any problems not addressed in the operating
instructions, please contact your CHARDER MEDICAL service
partner, or visit us on the Internet at www.chardermedical.com
GENERAL INFORMATION
We strongly recommend you use the scales on flat and hard surface.
Any soft surface, like carpet will cause inaccuracy.
SAFETY INSTRUCTION
Before putting the device into use, please read with care the
information given in the Operating Instructions. They contain
important instructions for installation, proper use and maintenance
of the device.
The manufacturer shall not be liable for damages arising out of
failure to heed the following instructions:
These batteries should be kept away from small children. If
swallowed, promptly seek medical assistance.
Expected Service Life: 5 years
When using electrical components under increased safety
requirements, always comply with the appropriate regulations.
Improper installation will render the warranty null and void.
Ensure the voltage marked on the power supply unit matches
your mains power supply.
This device is designed for use indoors.
Observe the permissible ambient temperatures for use
The device meets the requirements for electromagnetic
compatibility. Do not exceed the maximum values specified in
Page 4
3
the applicable standards.
These batteries should be kept away from all children. If swallowed,
promptly seek medical assistance.
If you have any problem, please contact your local CHARDER
MEDICAL service partner.
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
Page 5
4
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
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.
WARRANTYLIABILITY
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.

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 MEDICAL SCALE MS5710
is used exceeds the applicable RF compliance level above, the MEDICAL
SCALE MS5710 should be observed to verify normal operation. If abnormal
performance is observed, additional measures my be necessary, such as
re-orienting or relocating the MEDICAL SCALE MS5710.

The MEDICAL SCALE MS5710 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the MEDICAL SCALE MS5710 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the MEDICAL SCALE
MS5710 as recommended below, according to the maximum output power of
the communications equipment.

USING SCALE
WEIGHING
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.
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 5710 and MS 5711 / MS5712 are provided with the integrated
hold function (determination of average value). It enables people to
be weighed accurately although they are not still on the scale plate.
Once the key is pressed, the weight reading will remain on
the display after the item has been removed from the scale so the
reading can easily be read.
Note: Determination of average value is not possible when a person
moves too much.
Page 22

(2)
(1)
Switch ‘ON’ the scale using key. The diagnostic self-checks
is performed. The scale is ready for weighing when the „0.0 kg”
displays on the screen.
Place object/ person in the center of the scale plate.
Press the key. When the triangle is flashing on the display,
the scale records the fluctuating weight values and then
calculates average weight and displays the result on the screen.
Remove the object/ person from the scale platform. The object/
person’s weight reading will remain on the display.
Press the key again to return the scale to the normal
weighing mode.
HOLD 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 key before the person
moves on the tread platform.
Page 23
22
USING TARE FUNCTION
Tare allows the user to zero the instrument to cancel the weight of a
container/ clothes from the reading of the instrument, thus giving the
true weight of the product/ person being tested.
Place the object need to be tare on the tread platform.
Press key after the weight stabilizes and stable sign
displays.
Place the object need to be weighed (without removing the tare
object)
To delete the saved tare value, remove the tare object from the tread
platform and press key.
Page 24
23
USING BMI FEATURE
For BMI calculation, height is needed, therefore it is recommended
to measure the height of subject before starting weighing procedure
and the height must be in centimeters.
MS 5710/5711/5712
1. Turn on the scale using key.
2. Proceed to weigh as normal.
3. After the weight is stable and stable sign displays on the
screen long press key for 3 seconds.
4. Display will change to display.
5. Enter the height of the person using and
key- (For example: To enter 186cm, use
key to change the number and Use key to move to next
digit).
6. Press or key to confirm the height.
