Troubleshooting
| Problem | Solution |
|---|---|
| No display on main unit. | Check battery polarity. Replace with fresh batteries. Ensure batteries are properly seated. |
| Outdoor temperature/humidity not displaying or inaccurate. | Ensure outdoor sensor batteries are fresh and correctly inserted. Relocate sensor closer to the main unit. Check for obstructions between sensor and main unit. Reset both units by removing batteries, waiting 1 minute, then reinserting. |
| Atomic time not syncing. | Place the unit near a window, away from electronics that may cause interference. Allow up to 24 hours for sync. Manually set time if necessary. |
| Inconsistent readings. | Ensure sensors are not in direct sunlight or near heat/cold sources. Verify proper ventilation around sensors. |
