For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING

Recommended separation distances between portable and mobile RF communications equipment and the FT90

The FT 90 is intended for use in an electromagnetic environment in which radiated RF disturbances

are controlled. The customer or the user of the FT 90 can help prevent electromagnetic interference by

maintaining a minimum distance between portable and mobile RF communications equipment (trans-

mitters) and the FT 90 as recommended below, according to the maximum output power of the commu-

nications equipment.

1 1.2 1.2 2.3

10 3.8 3.8 7.3

100 12 12 23

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 trans-

mitter, 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 reection from structures, objects and people.
