Recommended separation distances between portable and mobile RF communications
equipment and the model BP3SK1-3B
The Model BP3SK1-3B is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the Model BP3SK1-3B
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Model BP3SK1-3B
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 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 absorption and reection from structures, objects and people.
