Before you begin

Refer to the Clock section for instructions on properly setting the Clock.

Battery back-up operation

• This clock is equipped with a time back-up system that is powered by 2 AAA batteries (not included). The power failure protection circuit will not operate unless batteries are installed.
• When normal household power is interrupted, or AC line cord is unplugged, the battery backup will power the clock to keep track of time and alarm settings programmed into memory.
• Normal operation will resume after AC power is restored so you will not have to reset the time or the alarm.

Note: It is recommended to replace the batteries at least once per year even if no power failures have occurred.

To install the batteries:

1. Open the battery compartment on the back of the clock by pressing on the tab and removing the cover.
   
2. Insert 2 AAA batteries (not included). Make sure to match the battery polarity marked in the battery compartment.
3. Put the cover back on the compartment and click it into place.

Power failure indicator

If you have not installed batteries in the product, or the batteries run out while AC power is disconnected, the clock and alarm settings will be lost. After AC power is reconnected, the time 12:00 will be shown on the LCD screen to indicate that power was interrupted and you should readjust the time settings.
