How to fix AcuRite 13020 Alarm Clock no outdoor sensor reception?
- SSandra MillerJul 26, 2025
If your AcuRite Alarm Clock isn't receiving the outdoor sensor signal (no bars), try these steps: First, relocate the display unit and/or the outdoor sensor, ensuring they are within 330 ft (100 m) of each other. Also, position both units at least 3 feet (.9 m) away from electronics like TVs, microwaves, and computers that might cause interference. Ensure you're using standard alkaline batteries (or lithium batteries in the sensor for temperatures below -4ºF/-20ºC), avoiding heavy-duty or rechargeable batteries. After replacing batteries, allow up to 20 minutes for the display unit and sensor to synchronize.
