5. Einrichtung
5.1. Einlegen der Batterie
- Open the battery compartment cover on the back of the alarm clock (refer to Image 4.2).
- Legen Sie die beiden AAA-Batterien ein und achten Sie dabei auf die richtige Polarität (+ und -).
- Schließen Sie den Batteriefachdeckel fest.
The alarm clock will power on automatically and begin searching for the DCF radio signal.
5.2. DCF Radio Signal Reception
Upon initial power-on or after battery replacement, the alarm clock will automatically attempt to receive the DCF radio time signal. This process can take several minutes. During reception, a signal icon may flash on the display. Once the signal is successfully received, the time will be set automatically, and the signal icon will appear steadily. For best reception, place the alarm clock near a window and away from electronic devices that may cause interference.
The DCF signal also ensures automatic adjustment for daylight saving time (summer/winter time).
5.3. Manual Time Setting (Optional)
Falls das DCF-Signal nicht verfügbar ist oder Sie die Zeit lieber manuell einstellen möchten:
- 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.
- Verwenden Sie die Tasten "+" oder "-", um die Minuten einzustellen.
- Press "SET" to confirm and exit manual setting mode.
- Repeat similar steps to set the date and year if necessary.
