Route cables carefully, to avoid tripping.
Keep the device away from liquids.
Always disconnect the device from mains power before cleaning.
Caution
Injuries and Infections
For hygiene purposes, Charder recommends cleaning the measuring
platform after each measurement with a soft cloth and alcohol.
Ensure that the measuring platform is dry before usage.
Caution
Preventing Device Damage
Please contact your local Charder distributor for regular maintenance
and calibration.
This device does not contain any user-maintained parts. All
maintenance, technical inspections, and repairs should be conducted
by an authorized Charder service partner, using original Charder
accessories and spare parts. Charder is not liable for any damages
arising from improper maintenance or usage. Dismantlement of the
device will void the warranty.
Take care to make sure fluids do not enter the device, as they may
damage the internal electronics.
Switch off the device before disconnecting the power supply.
Do not place the device in direct sunlight, or in close proximity to an
intense heat source. Excessively high temperatures may damage the
internal electronics.

NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic

propagation is affected by absorption and reflection from structures, objects and
people.
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 MS4910 is used exceeds the applicable RF compliance
level above, the MS250 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
re-orienting or relocating the MS4910
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.
Recommended separation distance between
portable and mobile RF communications equipment and the MS4910
The MS4910 is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the MS4910 can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the MS4910 as
recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (m) can be estimated using the equation applicable to
the frequency of the transmitter, where p is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.

applies.
