SECTION 6: TROUBLESHOOTING and INFORMATION

Operating Range of Batteries

Extended cold temperatures (below -4°F / -20°C) can cause alkaline batteries to function improperly, potentially stopping outdoor sensor transmission. Use lithium batteries in these low-temperature conditions for continued operation.

Set Wireless ID

This wireless weather station uses 433 MHz radio frequency for communication. To resolve interference or reception problems, ensure the selectable wireless ID (A, B, or C) matches on the main unit and all three wireless sensors. The ID switches are located within the battery compartments.

About the Atomic Clock

An atomic clock is accurate to one second in a million years. Consumer atomic clocks attain this accuracy by receiving signals from an atomic clock. In North America, the National Institute of Standards and Technologies operates an atomic clock in Colorado that transmits time codes via the WWVB radio station. The AcuRite clock has a built-in receiver for this signal. Due to solar radiation, the daytime signal is weaker; most synchronization occurs at night when interference is less.
