Recommended separation distances between portable and mobile RF communications
equipment and the FlexScan L761T-C
The FlexScan L761T-C is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the FlexScan L761T-C can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the FlexScan L761T-C 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 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.
