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 main 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 question, 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 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.

TROUBLESHOOTING
Troubleshooting for defective modes:
Ori inal purchaser can enjoy the benefits under the effective Warranty
a ainst functional defects in material and workmanship subject to the
terms and conditions listed in the yearly Warranty Pro ram & Return
Policy.
Our warranty service pro ram includes the followin :
1. Technician repair service under warranty or at a service
maintenance charge depending on the workmanship for the
defective functionality or cause of damage covered by the
warranty.
2. Parts replacement from the manufacturing factory under the
warranty or at a certain cost for the replaced parts plus the
workmanship charge if not covered under the warranty.
Before you contact our Authorized Dealer in your country for technician
repair service, please read throu h the followin section carefully:
Self-checking Tips:
Some functional defects can be identified and maintained by
users as listed below:
1. Power-on failure
Check if the main power adaptor has not plu ed onto the scale
properly
Check if the battery power is runnin low - Replace with new
batteries

38
ERROR MESSAGE
Low Battery
1. Check battery voltage (>6.4V) and if needed replace new
battery for operation.
. If the problem still persists inspect soldering of controller
PCB or replace the controller PCB.
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 or too low.
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.
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.
. 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.
AD Error
This indicates there is a fault with the scale’s software and is
normally caused by a fault with the PC board. Contact your
local service representative.
Negative weighing
When weight below - kg, the display will shows “-----“.
Press ZERO to return to the normal mode.

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 MS3850
is used exceeds the applicable RF compliance level above, the MEDICAL
SCALE MS3850 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 MS3850.

The MEDICAL SCALE MS3850 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the MEDICAL SCALE MS3850 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the MEDICAL SCALE
MS3850 as recommended below, according to the maximum output power of
the communications equipment.

Zero the scale
Press while scale is on to zeroin the scale
2Straight weighing
1. Place wei hin object/person on the scale
2. Wait until the stability si n appears
3. Read the wei hin result
3Weighing with hold
This device is 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 HOLD ey 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.
Symbol Information Remark
Stability sign Mark appears when weight is stable
Negative sign When weight value is negative
Zero indication When scale is set to zero
Battery symbol Indicate 5 level of battery power.

18
Note
Determination of average value is not possible when a person moves too much.
HOLD function won’t work if the weight is under 2 kg.
1. Switch on the scale. The diagnostic self-checks is performed. The
scale is ready for weighing when the „0.0 kg” displays on the
screen.
2. Place object/person on the scale.
3. Press 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.
4. Remove object/person from the scale. The weight reading will
remain on the display.
5. Press key again to return the scale to the normal weighing
mode.
6. HOLD function can be activated before or after place the weight
on the SC LE.
4Weighing with tare
Tare function allows the user to deduct the e cess weight of a single tare object
value (additional loads or clothes) from the display reading, thus calculate the
actual net weight of the object/ person.
4.1.1 Taring
Place tare object (additional loads or clothes) on scale and
press to tare the weight of object.
The zero display and the symbol NET appear.
The tare weight remains stored until it is cleared.
