2.2 Aatomiaja sünkroniseerimine

After battery installation, the clock will automatically attempt to retrieve the WWVB time calibration signal sent by NIST. This process ensures accurate time to the second and automatically adjusts for Daylight Saving Time (DST).

The clock will search for WWVB time airwave signals at 1:00 AM, 2:00 AM, and 3:00 AM each day to correct the time.
To ensure better reception, place the clock in an area with a good signal, such as near a window.
The clock supports 7 time zones: AST, EST, CST, MST, PST, AKT, HAT. Ensure you select the correct time zone before the clock calibrates.
