Get Started Quickly
1. Adjust the outdoor temperature link channel of clock and outdoor sensor to be same,like A-A, B-B, C-C.
2. Install batteries (3xAAA for clock and 2xAA for outdoor sensor) and choose your time zone.
3. Outdoor temperature starts to connect first, once finished, clock starts to search for WWVB signal.
4. Put clock to a place with good signal for better reception and outdoor sensor to a safe place outside within 330feet/100m.
5. Clock updates time automatically when signal received successfully.
Tips:
In most areas, a signal can only be received at night. If your clock does not receive WWVB signal in daytime, please wait overnight and it will be set in the morning.
