There may be too many physical barriers between the MAIN DISPLAY and the OUTDOOR VANE

Most electronic Weather Stations use a radio frequency to connect the MAIN DISPLAY and the OUTDOOR VANE

1. Consider the amount and thickness of barriers (such as walls) between the MAIN DISPLAY and the OUTDOOR VANE
2. Try moving the MAIN DISPLAY to an area closer to the OUTDOOR VANE
3. Check your settings to ensure the MAIN DISPLAY and OUTDOOR VANE are operating on the same frequency
4. Try resetting your Weather Station components
5. Try replacing the batteries in both MAIN DISPLAY and the OUTDOOR VANE
   • Always use good quality alkaline batteries
   • Note that extreme temperatures can effect battery performance
