5. Installation
5.1. Installation de la batterie
- Open the battery compartment cover on the back of the alarm clock (refer to Image 4.2).
- Insérez les deux piles AAA en respectant la polarité (+ et -).
- Fermez soigneusement le couvercle du compartiment à piles.
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. Réglage manuel de l'heure (facultatif)
Si le signal DCF n'est pas disponible ou si vous préférez régler l'heure manuellement :
- 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.
- Utilisez les boutons « + » ou « - » pour régler les minutes.
- Press "SET" to confirm and exit manual setting mode.
- Repeat similar steps to set the date and year if necessary.
