SAFETY PRECAUTIONS
Recommended separation distance between portable and mobile RF commu-
nications equipment and the Model BD-X201M
The Model
BD-X201M
is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the Model
BD-X201M
can help prevent electromagnetic interference by maintaining a minimum dis-
tance between portable and mobile RF communications equipment (transmitters) and the Model
BD-X201M
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 watt (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.
