4. Configuració
4.1 Alimentació de la unitat principal
- Insert 2 x LR6 AA batteries into the battery compartment on the back of the main unit, observing polarity (+/-).
- Alternatively, connect the provided USB power cord to the DC 5V port on the main unit and plug it into a compatible USB power adapter (not included).
4.2 Instal·lació del sensor exterior
- Insert 2 x LR6 AA batteries into the battery compartment of the outdoor sensor, observing polarity (+/-).
- Place the outdoor sensor in a shaded area, protected from direct sunlight and precipitation, to ensure accurate readings. It can be wall-mounted or placed on a flat surface using its integrated stent.
- Ensure the outdoor sensor is within 60 meters (197 feet) of the main unit for optimal wireless signal reception. The RF through-the-wall technology allows for flexible placement.

4.3 Sincronització inicial
After inserting batteries into both units, the main unit will automatically search for the outdoor sensor. This process may take a few minutes. Once connected, the outdoor temperature and humidity will appear on the main unit's display.
5. Instruccions de funcionament
5.1 Configuració de l'hora i la data
Refer to the user manual included in the package for specific button functions and navigation. Generally, a 'MODE' or 'SET' button will allow you to cycle through settings for time (12/24 hour format), year, month, day, and day of week language. Use '+' and '-' buttons to adjust values.
5.2 Configuració de l'alarma
The weather station includes an alarm clock function. Consult the detailed instructions in your physical user manual for setting the alarm time and activating/deactivating it.
5.3 Interpretació de la previsió meteorològica
The weather station analyzes barometric pressure trends to predict upcoming weather conditions. The forecast is displayed using intuitive icons (e.g., sunny, cloudy, rainy). This is a prediction and may not always perfectly match actual weather.
5.4 Visualització de temperatura i humitat
The main unit displays both indoor and outdoor temperature and humidity. You can typically switch between Celsius (℃) and Fahrenheit (℉) for temperature readings.
5.5 Visualització de pressió baromètrica
The current barometric pressure is displayed, often with a trend indicator (rising, steady, falling) to aid in weather prediction.
5.6 Comfort Level Display
The indoor comfort level is calculated based on indoor temperature and humidity, providing a visual indication of comfort (e.g., too dry, comfortable, too wet). There are 5 levels of comfort indication.

Figure 6: Visual representation of the 5 comfort levels displayed on the weather station, ranging from comfortable to cold or hot.
5.7 Moon Phase Display
The weather station displays the current moon phase, which updates automatically based on the set date.
5.8 Llum de fons
The LCD display features a backlight for improved visibility in low-light conditions. Refer to your manual for instructions on activating and adjusting the backlight.
6. Manteniment
6.1 Substitució de la bateria
When the battery indicator appears on the display, replace the batteries in both the main unit and the outdoor sensor with new LR6 AA batteries. Ensure correct polarity.
6.2 Neteja
Wipe the weather station and sensor with a soft, damp drap. No utilitzeu productes de neteja abrasius ni dissolvents, ja que poden danyar els components de plàstic o la pantalla.
6.3 Consideracions de col·locació
Per obtenir un rendiment i una longevitat òptims:
- Unitat principal: Place the main unit indoors on a stable surface or mount it on a wall. Avoid direct sunlight, heat sources, or areas with high electromagnetic interference.
- Sensor exterior: Position the outdoor sensor in a location that is protected from direct weather elements (rain, snow, direct sun) but still allows for accurate ambient temperature and humidity readings. A shaded, well-ventilated area is ideal.

Figure 7: The weather station can be conveniently mounted on a wall using the integrated hanging slot.

Figure 8: The weather station is also designed to stand on a table or flat surface using its built-in stand.
7. Solució De Problemes
If you encounter issues with your weather station, please refer to the following common solutions:
- No es permet llegir a l'aire lliure: Ensure batteries are correctly installed in the outdoor sensor and main unit. Check that the sensor is within range and not blocked by excessive interference. Try re-synchronizing by removing and reinserting batteries in both units.
- Lectures inexactes: Ensure the outdoor sensor is placed in a shaded area, away from direct sunlight or heat sources. For indoor readings, ensure the main unit is not near appliances that generate heat or cold.
- La pantalla no funciona: Check battery levels or ensure the USB power cord is securely connected. Replace batteries if necessary.
- Previsió meteorològica incorrecta: Weather forecasts are predictions based on barometric pressure changes and may not always be 100% accurate. Allow the unit time to gather data after setup.
