Recommended separation distances between portable and
mobile RF communications equipment and the 500
The
500
is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the
user of the
500
can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the
500
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 absorption and reflection
from structures, objects and people.
3. Guidance Notes
1.
When storing the
500
for long periods (greater than 1 month) or
during transport between sites the batteries should be removed.
