For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Recommended separation distances between portable and mobile RF communications equipment and the SR BM 1
The SR BM 1 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of the SR BM 1 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communica-
tions equipment (transmitters) and the SR BM 1 as recommended below, according to the maximum output power of the communications equip-
ment.

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.
