5. Fejlfinding
If you encounter issues with your SMARTRO SC91, refer to the following common problems and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Intet display eller svagt display | Ingen strøm eller lave batterier. | Ensure DC adapter is properly connected. Replace AA batteries if running on battery power or for backup. |
| Udendørs temperatur/fugtighed vises ikke eller er unøjagtig | Sensor uden for rækkevidde, lavt sensorbatteri eller interferens. | Move sensor closer to the main unit. Replace sensor batteries. Avoid placing near large metal objects or electronic devices. Re-sync sensor by removing and reinserting batteries in both units. |
| Projektionen er sløret eller utydelig | Incorrect projection distance or focus. | Adjust the distance between the clock and the projection surface (optimal 5-13ft). Ensure the projection lens is clean. |
| Alarmen lyder ikke eller er for stille | Alarmen er ikke aktiveret, eller lydstyrken er for lav. | Check if the alarm is enabled via the switch on the back. Ensure the alarm volume is set appropriately (if adjustable). |
| Vejrudsigten er upræcis | Initial setup or local atmospheric pressure changes. | The weather forecast is based on barometric pressure changes over time. Allow 7-14 days for the station to learn local atmospheric pressure. It predicts trends, not real-time weather. |
