Guidance and manufacturer’s declaration – electromagnetic immunity

BM 60 is intended for use in the electromagnetic environment speciﬁed below. The customer or the user of BM 60 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 BM 60, including cables, than the recommended separation distance calculated from

the equation applicable to the frequency of the transmitter.

Recommended separation distance:

d = [ 3.5 / V1 ]

d = [ 3.5 / E1 ] 80 MHz to 800 MHz

d = [ 7 / E1 ]

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,

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 structures,

objects and people.

Field strength from ﬁxed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM

and FM radios 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 BM 60 is

used exceeds the applicable RF compliance level above, BM 60 should be observed to verify normal operation. If abnormal performance is

observed, additional measures may be necessary, such as reorienting or relocating BM 60.

Over the frequency range 150 kHz to 80 MHz, ﬁeld strengths should be less than [V1] V/m.
