Note:
1 CR2450 battery is included with the unit. Pull battery tab 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 over-tighten. Confirm that
the backup battery indicator is not flashing in the display.
Note: Make sure you dispose of batteries properly (see your local regulations)
