Mains power quality should
be that of a typical

environment. If the user of
the equipment requires
contained operation during
power mains interruptions,
it is recommended for the
equipment to be powered
from an uninterruptible
power supply.

Portable and mobile RF communications
equipment should be used no closer to any part
of the EQUIPMENT, including cables, than the
recommended separation distance calculated form
the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
Where P is the maximum output power rating of
the transmitter in watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
"should be less than the compliance level in
