For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Recommended separation distances between portable and mobile
RF communications equipment and the 28075 / NB-810B
The 28075 / NB-810B is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the
28075 / NB-810B can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications
equipment (transmitters) and the 28075 / NB-810B 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.
