Recommended Separation Distances Between Portable and Mobile RF Communications Equi-
The AMM213TD/AMM240WTD system is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The user of the AMM213TD/AMM240WTD system can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the AMM213TD/AMM240WTD system 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 me-
ters (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.
