Recommended separation distances between portable and mobile RF communications equipment and the SBM 36
The SBM 36 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
SBM 36 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equip-
ment (transmitters) and the SBM 36 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.
