Recommended separation distances between portable and mobile RF communications equipment and the BC 28
The BC 28 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of the BC 28 can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the BC 28 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
determined 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 reflection
from structures, objects and people.
