Recommended separation distances between portable and mobile RF
The BM90 is intended for use in an electromagnetic environment in which radiated RF disturbances are con-
trolled. The customer or the user of the BM90 can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the BM90
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 meters (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 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 affected by absorpti-
on and reflection from structures, objects and people.
