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

should be at levels characteristic
of a typical location in a typical
commercial or hospital
environment.
