5 Solución de problemas
If you encounter issues with your SMARTRO SC91, refer to the following common problems and solutions:
| Problema | Causa posible | Solución |
|---|---|---|
| Sen pantalla ou pantalla escura | Sen electricidade ou baterías baixas. | Ensure DC adapter is properly connected. Replace AA batteries if running on battery power or for backup. |
| Outdoor temperature/humidity not displayed or inaccurate | Sensor fóra de alcance, batería baixa do sensor ou interferencias. | 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. |
| Projection is blurry or unclear | Incorrect projection distance or focus. | Adjust the distance between the clock and the projection surface (optimal 5-13ft). Ensure the projection lens is clean. |
| Alarm not sounding or too quiet | A alarma non está activada ou o volume é demasiado baixo. | Check if the alarm is enabled via the switch on the back. Ensure the alarm volume is set appropriately (if adjustable). |
