Obrázek 4.2: Wireless Transmission Range. The outdoor sensor transmits data wirelessly to the main unit up to 330 feet (100 meters) in open areas.
4.4 Atomic Clock (WWVB) Function
The weather station features a WWVB function that automatically searches for the atomic clock signal and updates the time daily at 1:00 am, 2:00 am, 3:00 am, 4:00 am, and 5:00 am.
After the RF connection is established, the weather station will automatically receive the atomic clock signal. The RCC receiving dot icon “●” will flash. During this process, the screen and backlight may darken. This is normal behavior as the station is receiving the signal; please wait patiently for it to complete.
