Maintenance
To ensure the longevity and optimal performance of your Acedeck L01 alarm clock, follow these simple maintenance guidelines:
- Cleaning: Wipe the clock with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the finish.

- Placement: Place the clock on a stable, flat surface away from direct sunlight, excessive heat, or moisture.
Troubleshooting
| Problem | Solution |
|---|---|
| Clock display is off. | Ensure the AC adapter is securely plugged into both the clock and a working power outlet. If using battery backup, the display turns off to save power, but the alarm function remains active. |
| Alarm does not sound. | Check if the alarm (AL1 or AL2) is activated (icon visible on display). Verify the alarm time is set correctly. Ensure the alarm volume is not set to zero. If running on battery backup, ensure batteries are fresh. |
| Time is incorrect. | Re-set the time following the 'Setting the Time' instructions. Check for power interruptions; if frequent, ensure battery backup is installed and functional. |
| USB charging is not working. | Ensure the alarm clock is connected to AC power. The USB charging port does not function when the clock is running on battery power. Check the USB cable and the device being charged. |
