Mains power quality should be that
of a typical commercial or hospital
environment. If the user of our
product requires continued
operation during power mains
interruptions, it is recommended
that our product 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.
Note: UT is the A.C. mains voltage prior to application of the test level.
