Recommended separation distances between portable and mobile
RF communications equipment and the EQUIPMENT or SYSTEM -
for EQUIPMENT and SYSTEMS that are not LIFE-SUPPORTING
Recommended separation distances between
portable and mobile RF communications equipment and the model BP3MX1-3C(WatchBP Home A
BT)
The Model BP3MX1-3C(WatchBP Home A BT) is intended for use in an electromagnetic
environment
in which radiated RF disturbances are controlled. The customer or the user of the
Model BP3MX1-3C(WatchBP Home A BT) can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Model BP3MX1-3C(WatchBP Home A BT) 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 metres (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.
