Recommended separation distance between
portable and mobile RF communications equipment and the TRC-50DX
The TRC-50DX is intended for use in an electromagnetic environment in which radiated RF dis-
turbances are controlled. The customer or the user of the TRC-50DX can help prevent electro-
magnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the TRC-50DX as recommended below, accord-
ing to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separa-
tion distance d in metres (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
NOTE 2
At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
