Recommended separation distances
The recorder is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. Electromagnetic
interference can be prevented by maintaining a minimum distance
between portable or mobile RF communications equipment
(transmitters) and the recorder 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.
