Recommended Separation Distances
Recommended Separation Distance Between Portable and Mobile RF Communication Equipment
and the ME Equipment
The ME Equipment is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the ME Equipment can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the ME Equipment as recommended below, according to the maximum output power of
the communication 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 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.
