ons are very low and are not likely to cause any interference in nearby electronic equip-

Recommended separation distances between portable and mobile RF communications equipment and the FT55

The

FT55

series is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of

the

FT55

series can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications

equipment (transmitters) and the

FT55

series 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 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.

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 aected by absorption and reflection from structures,

objects and people.
