For best reception, place the alarm clock near a window and away from electronic devices that may cause interference.

If the DCF signal is not available or you prefer to set the time manually:
- Press and hold the "SET" button (or equivalent, refer to specific button labels on your device) for a few seconds until the time display starts flashing.
- Use the "+" or "-" buttons to adjust the hours.
- Press "SET" again to confirm the hours and move to minutes.
