Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the
DR-17G and DR-22G requires
continued operation during
power mains interruptions, it is
recommended that the DR-17G
and DR-22G be powered from an
uninterruptible power supply or a
battery.

NOTE:
UT is the a.c. mains voltage prior to application of the test level.
Mains power quality should be that of a typical commercial or hospital environment. If the user of the DR-17G
and DR-22G requires continued operation during power mains interruptions, it is recommended that the
DR-17G and DR-22G be powered from an uninterruptible power supply or a battery.
