Replacing and Installing Clock Backup Battery

Note: 1 CR2450 battery is included with the unit. Install it 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 battery is getting weak the Low Backup Battery Indicator will begin flashing in the display.

When you see this flashing indicator you should replace the backup battery as soon as possible.

To install/replace the backup battery:

IMPORTANT: When replacing the backup battery 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. Use a Phillips screwdriver to unscrew the battery door located on the

bottom of the unit. Remove the battery door. If replacing battery,

remove the exhausted battery.

2. Insert 1 fresh CR2450 battery in the backup battery compartment.

Make sure the “+” side of the battery is facing you (see illustration).

3. Replace the battery door and screw shut. Do not overtighten. Confirm

that the backup battery indicator is not flashing in the display.

Note: Make sure you dispose of batteries properly (see your local regulations)
