Time-Protecting Battery Back-Up
(continued)
Operation
The time battery back-up is designed to
keep the clodt operating in the event of a
power failure or interruption. (Such as
when moving this unit to a different room.)
Whenever a power interruption occurs, the
clock display will disappear. However,
even though the display is completely
blacked out, the 9-volt back-up battery will
take over as the power source, preserving
present time and the alarm time.
Even if the power is not resumed by the
wake-up time, the buzzer alarm wll acti­
vate.
Notes
When the set is unplugged (not in use) for
a long time, remove the back-up battery to
prevent possible battery leakage.
Power failures may occur at any time of the
night or day and can be of a long or short
duration.
Most failures are so short that people don’t
even notice the interruption. These inter­
ruptions do, however, affect clocks which
do not incorporate a battery back-up.
If the power is not resumed by the wake-up
time, the radio alarm will not activate.
If the back-up battery goes dead during a
power interruption, the present time and
alarm time must also be reset after the
interruption.
The back-up battery will be exhausted
after about 23 hours of total (accumulative)
use. (The battery life will vary depending
on №e frequency of the power interrup­
tion.)
After a power interruption, the time shown
in the display window may not be always
correct (it may gain or lose approximately 6
minutes per hour).
