Recommended separation distances between portable and mobile RF communications equipment and the EM 49
The EM 49 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the EM 49 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the EM 49 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 reflection from structures, objects and people.
