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

should be at levels characteristic
of a typical location in a typical
