6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is off. | Not connected to power or power outage. | Ensure USB cable is securely connected to a power source. The memory battery only saves settings, not powers the display. |
| Projection is reversed or upside down. | Projection direction is incorrect. | The projector can only project towards the back of the clock. If projected forward, the numbers will appear reversed. Adjust the clock's orientation or the projection angle. |
| Alarm does not sound. | Alarm is not activated or set incorrectly. | Verify the alarm time and mode are set correctly. Ensure the alarm icon is visible on the display. |
| Cannot adjust settings. | Not in the correct setting mode. | Refer to the specific section in the operating instructions for the desired setting (e.g., SET for time, AL for alarm). |
