Troubleshooting
No Outdoor Temperature Display / Flashing Dashes:

- Reposition both units. Walls, large metal surfaces, and other electronics can interfere with the wireless signal.
- Perform a hard reset: Remove batteries from both units, wait 1 minute, then reinsert batteries into the outdoor sensor first, followed by the main display unit.
Inaccurate Temperature Readings:
- Ensure the outdoor sensor is placed in a shaded area, away from direct sunlight or heat sources (e.g., exhaust vents, windows).
- Allow 20 minutes for temperatures to stabilize after initial setup or relocation.
