Recommended separation distances between portable and mobile RF communications equipment
and the CanalPro CL
The CanalPro CL is intended for use in an electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or the user of the CanalPro CL can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the CanalPro CL 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 dis-
tance d in meters (m) can be estimated using the equation applicable to the frequency of the transmit-
ter, 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.
