Guidance and manufacturer’s declaration-electromagnetic immunity
The B100 is intended for use in the electromagnetic environment specified below.
The customer or the user of the B100 should assure that is used in such and environment.

Conducted RF

150 KHz to 80 MHz
N/A
Portable and mobile RF communications equipment should be used no closer to any part of
the B100 including cables, than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1,2 √P
d = 1,2 √P 80MHz to 800 MHz
d = 2,3 √P 800MHz 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:
Radiated RF
IEC 61000-4-3
3 V/m
80MHz to 2,5 GHz
3 V/m
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 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 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 B100 is used exceeds the applicable RF compliance level above, the B100 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the B100.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
