4. Guidance and manufacturer’s declaration – electromagnetic immunity – for
equipment and systems that are not life-supporting
The medical LCD monitor is intended for use in the electromagnetic environment specifi ed below.
The user of the medical LCD monitor should make sure that it is used in such an environment.

Portable and mobile RF communications equip-
ment should be used no closer to any part of the
medical LCD monitor, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
d = 1.2 P
Where P is the nominal power of the transmitter in
watts [W] according to the information provided
by the manufacturer of the transmitter and d is the
recommended separation distance in meters [m].
The fi eld strength of stationary transmitters at all
frequencies on site a should be, according to
a
study, less than the conformity level

Interference may occur in the vicinity of equipment
marked with the following symbol:
Note: These guidelines may not apply in all situations. The propagation of electromagnetic quantities is
aff ected by absorptions and refl ections of buildings, objects, and persons.
a
Field strengths from fi xed 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 of the stationary transmitters, a
site survey should be considered. If the measured fi eld strength in the location at which the device is used
exceeds the above conformity levels, the device should be observed to verify normal operation. If unusual
performance characteristics are observed, additional measures may be necessary, such as a modifi ed
orientation or a diff erent location for the device.
b
Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.
