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

Recommended separation distances between portable and mobile RF communications equipment and the boso unit
The boso unit is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the
user of the boso unit can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the boso unit as recommended below, according the the maximum output power of the com-
munications equipment.
For transmitter rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be estimated
using the equation applicable to the frequency of the transmitter, where p is the maximum output power rating of the transmitter in watts
(W) according the the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structu-
res, 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 boso unit is used exceeds the applicable RF compliance level above, the boso unit should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such als re-orienting or relocating the
boso unit.

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

Portable and mobile RF communications equip-
ment should be used no closer to any party of the
boso unit, 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 80 MHz to 800 MHz
d = 2,3 P 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 separa-
tion distance in metres (m).
Field strengths from fixed RF transmitters, as deter-
mined by an electromagnetic site survey,

should
be less than the compliance level in each frequency
range.
