Recommended separation distances between portable and mobile RF
communications equipment and the
MODEL NB603
The
MODEL 603
is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
MODEL NB603
can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment
(transmitters) and the
MODEL NB603
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 reflection from structures, objects and people.
