Table 204 – Recommended separation distances between portable and mobile
RF communications equipment and the equipment and system – for equipment
and systems that are not life supporting
Recommended separation distances between portable and mobile RF
communication equipment and the Protect 900.
The Protect 900 is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the
Protect 900 can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the Protect 900 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.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reection from structures, objects and
people.
