If the user of the device requires continued
operation during power mains
interruptions, it is recommended that the
device be powered from an uninterruptible
power supply.

Power frequency magnetic fields should be
at levels characteristic of a typical location
in a typical commercial or hospital
environment.
Portable and mobile RF communications
equipment should be used no closer to any
part of the device including cables, than
the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, ª should be less than the
compliance level in each frequency range.
