Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of the system requires continued
operation during power mains
interruptions, it is recommended
that the system be powered from
an uninterruptible power supply or
battery.

Field strengths from fixed transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance levels (V1 and
E1).
Interference may occur in the vicinity of equipment
containing a transmitter.
