2.3 Initial Time Synchronization
Upon initial power-up, the alarm clock will automatically attempt to synchronize with the DCF77 radio signal (atomic clock in Frankfurt, Germany). This process may take several minutes to a few hours, depending on your location and environmental conditions.
- Place the alarm clock near a window, away from electronic devices that might cause interference.
- A flashing antenna symbol on the display indicates that the clock is searching for the radio signal.
- Once synchronized, the antenna symbol will become solid, and the correct time will be displayed. The clock will automatically check and adjust the time, typically between 2:00 AM and 4:00 AM daily.
- If synchronization fails, you may need to manually set the time (refer to Section 3.1).
