Main power quality should be that
of a typical commercial or hospital
environment. If the user of the
PASCAL Synthesis Ophthalmic
Scanning Laser System requires
continued operation during main
power interruptions, it is
recommended that the SL-
PASCAL Synthesis Ophthalmic
Scanning Laser System be
powered from an uninterruptible
power supply or battery.

of a typical location in a typical
commercial or hospital
environment.
