Guidance and manufacturer’s declaration – electromagnetic immunity

The BC 16 is intended for use in the electromagnetic environment speciﬁed below. The customer or the user of the BC 16 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 BC 16, including cables, than the recommended separation dis-

tance calculated from the equation applicable to the frequency of the transmitter.

Recommended separation distance:

d = 1.2

d = 1.2 80 MHz to 800 MHz

d = 2.3

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 meters (m).

Field strengths from ﬁxed RF transmitters, as determined by an electromagnetic

site survey,

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

NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption and reﬂection from struc-

tures, 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

BC 16 is used exceeds the applicable RF compliance level above, the BC 16 should be observed to verify normal operation. If abnormal per-

formance is observed, additional measures may be necessary, such as re-orienting or relocating the BC 16.

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