Recommended Separation Distances Between Portable and Mobile RF Communications
Equipment and the Genesis DM
The Genesis DM is intended for use in the electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Genesis DM can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Genesis DM 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 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 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.
