GENERAL INFORMATION ON USAGE AND MAINTENANCE
Recommended separation distance between
portable and mobile RF communications equipment and the CT-1P/CT-1
The CT-1P/CT-1 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the CT-1P/CT-1 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the CT-1P/CT-1 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 sepa-
ration distance d in meters (m) can be estimated using the equation applicable to the fre-
quency 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 propaga-
tion is affected by absorption and reflection from structures, objects and
people.
