- 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.
- Norėdami reguliuoti mirksinčią reikšmę (pvz., valandą, minutę, metus, mėnesį, dieną), naudokite mygtukus „+“ arba „-“.
- Press 'SET' again to confirm and move to the next setting.
- Exit setting mode by not pressing any button for a few seconds, or by cycling through all settings.
6.3 Ekrano režimai
- 12/24 valandų formatas: The clock supports both 12-hour (with AM/PM) and 24-hour time displays. This setting can typically be toggled via a button on the rear panel or during manual setup.
