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.
