Recommended separation distances between portable and mobile RF communications equipment
and the M270TF-XXX / M320TF-XXX
The M270TF-XXX / M320TF-XXX is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the M270TF-XXX / M320TF-XXX can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the M270TF-XXX / M320TF-XXX as recommended below,
per 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) per 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.
