Using the iBT230
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 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.
2. Insert 2 fresh AA batteries in the backup battery compartment. Make
sure the polarity of the batteries (“+” or “-” nodes) matches the
illustration.
3. Slide and 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)
