Recommended separation distance between portable and mobile RF communications
equipment and the Flex-MT® Plus
e Flex-MT® Plus is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. e the user of the Flex-MT® Plus can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the
Flex-MT® Plus 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 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. 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.
