PREPARATION
CONNECTING TO AC
POWER
Plug the clock radio’s power cord into
a standard AC outlet. The display
flashes.
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 dis-
play turns off, but the clock operates
for at least 8 hours if the time has been
set, and the alarm continues to sound
for at least 10 minutes after the power
failure. 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 type.
The BATTERY SENTINEL indicator
appears if the back-up battery is not in-
stalled or needs to be replaced. To
prevent unnecessary drain on the bat-
tery, install it only after connecting the
clock radio to AC power.
1. Push the battery compartment
latch in the direction of the arrow
and lift off the battery compart-
ment cover.
2. Snap the clock radio’s battery
contacts onto the battery’s termi-
nals, then insert the battery into
the compartment. The BATTERY
SENTINEL indicator turns off.
Note: If the BATTERY SENTI-
NEL indicator remains lit, press
SNOOZE to reset the indicator. If
the indicator remains lit after
SNOOZE is pressed, replace the
back-up battery.
3. Replace the cover.
Warnin
g
: Always dispose of old bat-
teries promptly and properly.
