PREPARATION
CONNECTING TO
AC POWER
Plug the clock radio’s power cord into a
standard AC outlet. The display flashes
and the BATTERY SENTINEL indicator
light next to the time display turns on
(see “Installing a Back-Up Battery”).
INSTALLING A BACK-UP
BATTERY
Your clock radio uses a 9V battery (not
supplied) to operate the clock and alarm
during a power failure. The display turns
off, but the clock keeps the time for at
least 8 hours, and the alarm will sound
(if set) for at least 10 minutes after pow-
er fails. For the best performance, we
recommend an alkaline battery, such as
RadioShack Cat. No. 23-553.
Caution: Use only a fresh battery of the
required size and recommended type.
Note: To prevent unnecessary drain on
the battery, install it only after connect-
ing the clock radio to AC power.
1. Press the tab and lift off the battery
compartment cover on the bottom of
the clock radio.
2. Snap the clock radio’s battery con-
tacts onto the battery’s terminals,
then insert the battery into the com-
partment. The BATTERY SENTI-
NEL indicator turns off.
Note: If the BATTERY SENTINEL
indicator remains lit, press
SNOOZE
to reset the indicator. If that does not
work, replace the back-up battery.
3. Replace the cover.
The BATTERY SENTINEL indicator
lights if the back-up battery is not in-
stalled or needs to be replaced.
Warning: Always dispose of old batter-
ies promptly and properly. Do not bury
or burn them.
