3. Asennus
3.1 Pääyksikön virran kytkeminen
- Connect the provided USB power cable to the DC5V1.2A port on the back of the weather clock.
- Kytke USB-kaapelin toinen pää yhteensopivaan USB-virtalähteeseen (ei sisälly toimitukseen) tai USB-porttiin.
- For backup power, insert one CR2032 battery (not included) into the battery compartment. This battery retains time and settings during power outages.
3.2 Powering the Remote Sensor
- Avaa langattoman kaukosäätimen anturin takana oleva paristolokero.
- Insert two AA LR06 batteries (not included), ensuring correct polarity (+/-).
- Sulje paristolokero kunnolla.
3.3 Anturin sijoittaminen ja parittaminen
Place the remote sensor outdoors in a shaded, dry location, away from direct sunlight and precipitation, to ensure accurate readings. The maximum transmission range is 60 meters in an open area.

Image 3.1: The weather station supports a 60-meter transmission range for its remote sensors in open areas. The display shows options for selecting different outdoor sensor channels (OUT 1, OUT 2, OUT 3).
The main unit will automatically attempt to connect with the remote sensor(s) upon initial power-up. If connection is not established, refer to the troubleshooting section.
3.4 Initial Weather Forecast Calibration
Upon first use, the weather station requires 7-10 days for learning and calibration to provide accurate weather forecasts. During this period, the forecast may not be fully reliable.

5.2 Puhdistus
Wipe the unit and sensor with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the surfaces.
6. Vianmääritys
- Ei ulkolämpötilan/kosteuden mittausta:
- Ensure the remote sensor batteries are correctly installed and not depleted.
- Verify the sensor is within the 60-meter transmission range and there are no major obstructions.
- Try re-pairing the sensor by removing and reinserting batteries in both the main unit and sensor, then power on the sensor first.
- Inaccurate weather forecast:
- Allow 7-10 days for the unit to complete its initial learning and calibration process.
- Ensure the unit is placed in a location where it can accurately sense atmospheric pressure changes.
- Projection is blurry or dim:
- Adjust the focus of the projection lens.
- Varmista, että huone on riittävän pimeä optimaalisen heijastusnäkyvyyden saavuttamiseksi.
- Näyttö on tyhjä tai välkkyvä:
- Check the USB power connection.
