Recommended separation distances between portable and mobile RF communications equipment and the EM 38
The EM 38 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the EM 38 can help prevent electromagnetic interference by maintaining a minimum distance bet-
ween portable and mobile RF communications equipment (transmitters) and the EM 38 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.
