of the FlexScan L761T-C requires
continued operation during
power mains interruptions, it is
recommended that the FlexScan
L761T-C 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.
