Guidance and manufacturer’s declaration – electromagnetic immunity

The BM 70 is intended for use in the electromagnetic environment speciﬁ ed below. The customer or the user of the BM 70 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 BM 70, 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 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 ﬁ xed 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 reﬂ ection from structures,

objects and people.

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 due to ﬁ xed RF

transmitters, an electromagnetic site survey should be considered. If the measured ﬁ eld strength in the location in which the BM 70 is used exceeds

the applicable RF compliance level above, the BM 70 should be observed to verify normal operation. If abnormal performance is observed, additio-

nal measures may be necessary, such as re-orienting or relocating the BM 70.

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