Recommended separation distances between portable and mobile RF communications equipment and the EM 29
The EM 29 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The cus-
tomer or the user of the EM 29 can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the EM 29 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 meters (m)
can be determined 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 reflec-
tion from structures, objects and people.
