8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock does not display anything. | No power or dead batteries. | Ensure AC adapter is properly connected. Replace AA batteries. |
| Radio-controlled time not setting. | Weak DCF77 signal, interference, or location too far from transmitter. | Move the clock to a different location, preferably near a window and away from other electronics. Allow several hours for synchronization. Set time manually if signal remains unavailable. |
| Projection is dim or unclear. | Projection lens dirty, room too bright, or not connected to AC power. | Clean the projection lens. Ensure the room is dark. The projection requires AC power for continuous operation. |
