2. Initial Time Synchronization (Radio Control)
Upon battery installation, the alarm clock will automatically attempt to synchronize with the DCF radio signal (Frankfurt, Germany) to set the correct time, date, and day of the week. This process may take a few minutes. For best reception, place the clock near a window and away from electronic devices that might cause interference.

- If the signal is weak or unavailable, the clock can be set manually.
