1. Important

Guidance and manufacturer’s declaration – electromagnetic immunity – for EQUIPMENT and

SYSTEMS that are not LIFE-SUPPORTING:
The monitor is intended for use in the electromagnetic environment specified below. The customer or

the user of the monitor should assure that it is used in such an environment.

Portable and mobile RF communications equipment

should be used no closer to any part of the 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

d = 1.2

800 MHz to 2.5 GHz

where P is the maximum output power rating of the

transmitter in watts (W) according to the transmitter

manufacturer and d is the recommended separation

distance in metres (m).
Field strengths from fixed RF transmitters, as determined

by an electromagnetic site survey:
a.

Should be less than the compliance level in each

frequency range.

Interference may occur in the vicinity of equipment

marked with the following symbol:

Note

• At 80 MHz and 800 MHz, the higher frequency range applies.

• These guidelines may not apply in all situations. Electromagnetic propagation is affected by

absorption and reflection from structures, objects and people.

• 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 monitor is used exceeds the applicable RF compliance level above,

the monitor should be observed to verify normal operation. If abnormal performance is observed,

additional measures may be necessary, such as reorienting or relocating the monitor.

• Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
