ENVIROMENTAL
All batteries contain toxic compounds; disposal of batteries should be
delegated to a competent organization, 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.
You are legally obliged to hand in used batteries/rechargeable batteries to a
local collection point so that they can be disposed of in an
environmentally-friendly way. When buying new batteries, select batteries low
in harmful substances and no mercury(Hg), cadmium(Cd) or lead(Pb).
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 turn off the scale 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 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 Hoist scale is designed to detect when a stable
weight is achieved, 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.

You can obtain further details from your local council, your municipal waste
disposal company or the firm which you purchased the product.
READING BEFORE USE
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 ZERO key to reset.
Note: Do not measure weight during movement, tilt will cause

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 MS4400
is used exceeds the applicable RF compliance level above, the MEDICAL
SCALE MS4400 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 MS4400.
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 and the MEDICAL SCALE
The MEDICAL SCALE MS4400 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the MEDICAL SCALE MS4400 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the MEDICAL SCALE
MS4400 as recommended below, according to the maximum output power of
the communications equipment.
