charging accessory requires continued
operation during power mains
interruptions, it is recommended that the
handle and charging accessory be
powered from an uninterruptible power

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 handle and charging
accessory, including cables, than the
recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
