Replacing and Installing Clock Backup Batteries

Note: 2 AAA batteries are included with the unit. Install them before using the unit. 

This model is equipped with a battery backup circuit that will maintain the time and alarm time settings in the event of 
a temporary power interruption (the display is NOT maintained). The battery backup circuit will also operate the 
buzzer alarm to wake you up at the selected wake up time even if the power is out.  When the backup batteries are 
getting weak the Low Backup Battery Indicator will begin flashing in the display. When you see this flashing indicator 
you should replace the backup batteries as soon as possible. Note: We recommend alkaline batteries for best 
performance.

To install/replace the backup batteries

IMPORTANT: When replacing the backup batteries be sure to have the unit connected to the AC outlet to maintain all of your 
settings, otherwise it will be necessary to reset the time and alarm time after the batteries are replaced.
1.  Slide and remove the battery door located on the bottom of the unit. 

If replacing batteries, remove the exhausted batteries.
