Replacing and
Installing Clock Backup Batteries
Note: 2 AA 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 lit). 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. Press tab to remove the battery door located on the back of
the unit. If replacing batteries, remove the exhausted batteries.
2. Insert 2 fresh AA batteries in the backup battery compartment.
Make sure the polarity of the batteries (“+” or “-” nodes)
matches the illustration.
3. Close the battery compartment door. Confirm that the backup
battery indicator is not flashing in the display.
Note
: Make sure you dispose of batteries properly (see your local regulations)
