human intervention.
The recorder is smart enough to know that if it is not recording or playing, it can shut off after 30

PRECAUTIONS.
It is not impossible to defeat the UPS’ utility. If your facility is subject to frequent power failures
of many seconds duration, it is possible to discharge the batteries faster than they are
automatically recharged. The unit protects itself by automatically shutting down if the battery
voltage gets too low, notwithstanding the timeout period. If this happens, it may be necessary to
reconstruct the media index.
Batteries have a limited service life and should be checked periodically by following the
recommendations in the maintenance section.
