Guidance and manufacturer’s declaration – electromagnetic immunity
The B30 is intended for use in the electromagnetic environment specified below. The customer or the user of
the B30 should assure that it is used in such an environment.

Electromagnetic environment - guidance
Portable and mobile RF communications equipment
should be used no closer to any part of the
equipment, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
Conducted RF
IEC 61000-4-6 3 Vrms
150 kHz to 80 MHz 3 Vrms
Radiated RF
IEC 61000-4-3 3 V/m
80 MHz to 2.5 GHz 3 V/m
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.
b
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 affected by
absorption and reflection from structures, objects and people.
a 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
predicated 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 equipment is used exceeds the applicable RF compliance level above, the
equipment should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the equipment.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
