Recommended Separation Distances between Portable and Mobile RF, Communications
Equipment and This Equipment
This equipment is intended for use in an electromagnetic environment in which radiated RF
disturbance are controlled. The customer or the user of this equipment can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and this equipment as recommended below, according to
the maximum output power of the communication equipment.

For transmitters at a maximum output power not listed above, the recommended separation distanced
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.
ote 1: At 80 MHz and 800 MHz, the higher frequency range applies.
ote 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
