Connect the provided DC 4.5V/150mA power adapter to the main unit's power input and then plug it into a wall outlet. The display will illuminate.
5.3. Sensor Placement and Synchronization
Place the outdoor sensor in a shaded, dry location away from direct sunlight and rain, ensuring it is within 30 meters (open area) of the main unit. The main unit will automatically attempt to synchronize with the sensor. This may take a few minutes. Once connected, the outdoor temperature and humidity will appear on the display.
5.4. Muntatzeko aukerak
- Mahaigaina: Use the integrated stand on the back of the main unit to place it on a flat surface.
- Hormako muntaia: Use the hanging hole on the back of the main unit to mount it on a wall using a screw (not included).
6. Funtzionamendu-argibideak
6.1. Bistaratu informazioa
The color LCD display shows the following information:
- Weather forecast icons (sunny, partly cloudy, cloudy, rain)
- Barruko tenperatura eta hezetasuna
- Kanpoko tenperatura eta hezetasuna
- Digital time (12/24 hour format)
- Asteko eguna eta eguna
6.2. Time and Date Settings
The weather station automatically receives the DCF77 radio signal for accurate time and date synchronization. If the signal is not available or you prefer manual setting:
- Eduki sakatuta EZARTU button (location may vary, refer to device markings) to enter manual time/date setting mode.
- Erabili GORA/BEHERA balioak doitzeko botoiak.
- Sakatu EZARTU again to confirm and move to the next setting (e.g., hour, minute, year, month, day, 12/24 hour format).
6.3. Tenperatura-unitatearen hautaketa
Sakatu ° C / ° F button (location may vary) to switch between Celsius and Fahrenheit temperature display.
6.4. Managing Additional Sensors
The SWS 4250 supports up to three outdoor sensors. To add additional sensors (purchased separately):
- Install batteries in the new sensor.
- Unitate nagusian, sakatu TXANELA button to cycle through available sensor channels.
- The main unit will automatically search for and connect to new sensors on an unused channel.
7. Mantentzea
7.1. Garbiketa
Garbitu unitate nagusia eta sentsorea zapi leun eta lehor batekinamp oihal. Ez erabili garbitzaile edo disolbatzaile urratzailerik, pantaila edo... kaltetu baitezakete.asing.
7.2. Bateria ordezkatzea
Replace batteries in both the main unit and the sensor when the low battery indicator appears on the display. Always replace all batteries in a set with new ones of the same type.
