5.2 Instalación das baterías no sensor exterior
The outdoor sensor requires 2 x AA batteries (not included).
- Abra o compartimento das baterías na parte traseira do sensor exterior.
- Introduza 2 pilas AA, respectando a polaridade correcta (+/-).
- Pecha o compartimento da batería de forma segura.
5.3 Pairing Sensors
The main unit automatically searches for the outdoor sensor upon initial power-up. If pairing fails or you are adding additional sensors:
- Ensure both the main unit and the outdoor sensor have power.
- On the outdoor sensor, select a channel (1, 2, or 3) using the channel switch.
- Press the "TX" button on the outdoor sensor to send a signal.
- On the main unit, press and hold the "CHANNEL" button for 3 seconds to initiate a search for outdoor sensors. The outdoor temperature/humidity display will flash.
- Once connected, the outdoor temperature and humidity will appear on the main unit.
The weather station supports up to three external wireless sensors. If using multiple sensors, ensure each is set to a different channel (1, 2, or 3).

5.4 Configuración inicial (hora, data, unidades)
After powering on, the unit will attempt to synchronize with the DCF radio signal. This may take several minutes or hours depending on your location. If you need to set the time manually or adjust other settings:
- Press and hold the "MODE" button for 3 seconds to enter time setting mode. The hour digit will flash.
- Use the "UP" or "DOWN" buttons to adjust the value.
- Press "MODE" to confirm and move to the next setting (Minute > Year > Month > Day > Time Zone > 12/24H format > Temperature Unit (°C/°F) > Pressure Unit (hPa/inHg)).
- Press "MODE" again to exit settings.
The DCF radio-controlled clock automatically synchronizes with the radio clock signal, ensuring accurate time. Select your time zone (-2 to +2), and the clock will adjust accordingly.
