3. Opsætning
3.1 Batteriinstallation
The weather station and outdoor sensor are battery-powered, allowing for flexible placement. Batteries are not included.
- Åbn batterirummet på bagsiden af hovedenheden.
- Indsæt 4x AAA batterier, observing the correct polarity (+/-).
- Luk batterirummet.
- Repeat steps 1-3 for the outdoor sensor.
Note: Ensure fresh batteries are used for optimal performance. High battery consumption may require replacement approximately every 6 months.
3.2 Indledende synkronisering
After battery installation, the main unit will automatically attempt to synchronize with the outdoor sensor and receive the DCF77 radio signal for time setting.
- Place the outdoor sensor within range of the main unit (ensure no major obstructions).
- The main unit will display outdoor temperature once synchronized. If synchronization fails, reposition the outdoor sensor or restart both devices by removing and reinserting batteries.
- The radio-controlled time signal (DCF77) will automatically set the correct time, including summer and winter time adjustments. This process may take several minutes.
3.3 Manuel tidsindstilling
If the radio signal is unavailable (e.g., in areas with poor reception), the time can be set manually.
- Refer to the detailed instructions in the operating section for manual time and date adjustments.
