- A solid signal icon indicates successful synchronization.
- A flashing icon indicates the clock is attempting to receive the signal.
6.2 Manual Time and Date Adjustment
In areas where the atomic signal is weak or unavailable, you can manually set the time and date.
- Locate the manual set buttons on the rear panel.
- Press the 'SET' button to enter setting mode.
- Folosiți butoanele „+” sau „-” pentru a ajusta valoarea care clipește (de exemplu, oră, minut, an, lună, zi).
