Recommended separation distances between portable and mobile RF communications equipment
The LMD-3251MT is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the LMD-3251MT can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the LMD-3251MT as recommended below, according to
the maximum output power of the communications equipment.

For transmitters rated 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.
