Recommended separation distances between portable and mobile RF communications equipment and the BM 20
The BM 20 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of the BM 20 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF commu-
nications equipment (transmitters) and the BM 20 as recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be esti-
mated 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 to 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 aff ected by absorption and refl ection from struc-
tures, objects and people.
