CONNECTING AC
POWER
Plug the clock radio’s power cord into
a standard AC outlet. The display
flashes
12:00 until you set the time.
INSTALLING A BACK-UP
BATTERY
Your clock radio has a back-up power
system that operates the clock and
alarm during a power failure. The dis-
play turns off, but the clock keeps run-
ning for at least 8 hours (depending on
battery strength), and the alarm
sounds at the alarm time for at least
10 minutes.
The Battery Sentinel indicator, a small
red dot at the bottom right of the dis-
play, appears if the battery is not in-
stalled or needs to be replaced.
Your clock radio requires a 9-volt bat-
tery (not supplied) for its back-up pow-
er system. 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 con-
necting the clock radio to AC power.
1. Push the battery compartment
latch and pull off the compartment
cover.
2. Snap the clock radio’s battery
contacts onto the battery termi-
nals, then insert the battery into
the compartment. The Battery
Sentinel indicator turns off.
3. Replace the cover.
Caution: Never leave an old or weak
battery in the clock radio. It could leak
and damage the clock radio’s elec-
tronic parts.
Warning: Always dispose of an old
battery promptly and properly. Do not
bury or burn it.
