Troubleshooting
| Problem | Solution |
|---|---|
| No outdoor temperature/humidity reading | Ensure batteries are correctly installed in the sensor. Move the sensor closer to the main unit. Avoid large metal objects or electronic devices that may interfere with transmission. Re-synchronize by removing and reinserting batteries in both units. |
| Incorrect temperature/humidity readings | Ensure the sensor is placed in a shaded, dry area, away from direct heat sources or extreme cold. Allow time for readings to stabilize after setup. |
| Display is blank or dim | Replace batteries in the main unit. Check battery polarity. |
