The power supply of
the networks should
be suitable for use in
typical business or
hospital environments. It
is recommended to use
an uninterruptible power
supply or batteries if the
user requires continuous
operation of the high-
flow device during a
power interruption.

The distance for the use
of portable and mobile RF
communications equipment
should be no less than the
recommended distance from
any part of the high-flow device,
including power cords. This
distance should be calculated
using the following formula: d =
1.2 P, which corresponds to the
transmitter frequency.
