Setup
Power Connection
Connect the supplied AC wall adapter to the DC jack located on the back of the unit. Plug the adapter into a standard working wall outlet. The clock display will illuminate.
Battery Backup Installation
For battery backup, install 2 AAA batteries (not included) into the battery compartment located on the bottom of the unit. Ensure the polarity (+/-) matches the diagram inside the compartment. These batteries will preserve your time and alarm settings in case of a temporary power interruption, but they do not power the main functions of the clock.

Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Clock display is blank or not working. | Ensure the AC power adapter is securely plugged into both the unit and a working wall outlet. The unit requires AC power for primary operation. |
| Cannot set time or alarm. | Ensure you are pressing and holding the correct "TIME SET" or "ALARM" button until the display flashes before attempting to adjust. Refer to "Operating Instructions" for detailed steps. |
| Radio presets are lost after unplugging. | The backup batteries (2 AAA, not included) are for maintaining time and alarm settings only, not radio presets. Radio presets are stored in volatile memory and will be lost if the unit is unplugged from AC power without backup batteries installed. |
| USB charging is not working or slow. | Ensure the USB cable is properly connected to both the clock and your device. Verify your device is compatible with standard USB-A charging. This port is for charging only. |
| Alarm is too soft or too loud. | Adjust the built-in volume switch (located on the top panel) to your desired level. The buzzer alarm starts softly and gradually gets louder. |
