Table 4 - Recommended Separation Distances
Recommended separation distances between portable and mobile RF communications
equipment and the Trex HD Monitoring
The
Trex HD Monitoring
is intended for use in the electromagnetic in which radiated RF disturbances
are controlled. The customer or user of the
Trex HD Monitoring
can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the
Trex HD Monitoring
as recommended below, according to the
maximum output power of the communications equipment.

For the 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
