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 disturbances are controlled. The customer
or the user of this equipment can help prevent electromagnetic interference by maintaining a minimum distance between the portable
and mobile RF communications equipment (transmitters) and this equipment 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.
