Configuració

2. Initial Synchronization (Atomic Time)
Upon battery insertion, the clock will automatically begin searching for the NIST Colorado Atomic Clock signal. This process allows the clock to self-set to the correct time, date, and adjust for Daylight Saving Time (DST) automatically. Please allow up to 24-48 hours for the clock to acquire the signal and fully synchronize. During this period, ensure the clock is placed in an area with minimal electronic interference and away from large metal objects.
3. Time Zone and DST Preference
After initial synchronization, you may need to select your specific time zone. Refer to the buttons on the back of the clock, typically labeled "TIME ZONE" or similar. Press the button repeatedly to cycle through available time zones until yours is displayed. You can also manually toggle the Daylight Saving Time (DST) preference ON or OFF if the automatic adjustment is not desired or if you are in a region that does not observe DST.
Instruccions de funcionament
