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.
INTENDED USE
This scale is used to determine weight of patients who are supported by
professional personnel in rooms intended for carrying out health care. The
weighing value can be read off after a stable weighing value has been
obtained. Before any use, the scale must be checked for correct condition
by the authorized person.
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

4
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 the applicable standards.
If you have any problem, contact your local CHARDER MEDICAL service
partner.
ENVIRONMENTAL
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.

5
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 important guidelines:
Always be sure that the display shows `Zero` before use, if it does not then
please press the ZERO key.
The Professional Medical scale is designed to detect when a stable weight is
achieved, the indicator will `beep` 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.

following reasons: Unsuitable or improper storage or use, incorrect installation
or commissioning by the owner or third parties, natural wear, changes or

6
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.
DISPOSING OF THE SCALE
This product is not to be treated as regular household waste, but should be
handed in to an electrical/electronic equipment recycling centre.
You can obtain further details from your local council, your municipal waste
disposal company or the firm which you purchased the product

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 MS 3500
is used exceeds the applicable RF compliance level above, the MEDICAL
SCALE MS 3500 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 MS 3500.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be les than

Recommended separation distance between portable and mobile RF
communications equipment and the MEDICAL SCALE
The MEDICAL SCALE MS 3500 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the MEDICAL SCALE MS 3500 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the MEDICAL SCALE MS
3500 as recommended below, according to the maximum output power of the
communications equipment.
