4. Setup
4.1 Power Supply
- Main Unit: Power via the included USB cable (DC 5V/1.2A) for continuous backlight and full functionality. Alternatively, use 2 x AA batteries (not included) for backup power, which will illuminate the screen for 15 seconds when activated.
- Outdoor Sensor: Requires 3 x AA batteries (not included). Ensure batteries are inserted correctly according to polarity markings.
4.2 Outdoor Sensor Installation
The multi-combination wireless outdoor sensor should be installed in an open area to ensure accurate readings for wind speed, wind direction, and rainfall. It has a transmission range of up to 100 meters (300 feet) in open areas.
- Choose a Location: Select a location free from obstructions (trees, buildings) that could interfere with wind, rain, or solar panel exposure. Ensure it is within the 100m range of the main unit.
- Mounting: Use the provided installation accessories to securely mount the sensor. The sensor includes a bubble level for proper horizontal alignment, which is crucial for accurate rainfall measurement.
- Orientation: Ensure the wind direction vane is oriented correctly (e.g., North arrow pointing North) for accurate wind direction readings.

5.2 Setting Time and Date
Refer to the detailed instructions in the included multi-language manual for specific button presses to set the time, date, and language preferences.
5.3 Alarm and Snooze Settings
The device supports two daily alarms. The alarm time, period, snooze time (5-60 minutes), and number of snoozes can be configured. Consult the full manual for step-by-step instructions.
5.4 Warning Functions
The weather station can be configured to issue warnings for:
- Upper and lower limits of temperature and humidity.
- Upper limit of wind speed.
- Upper limit of rainfall.
These limits are user-adjustable. An audible or visual alert will activate when a set limit is exceeded.
6. Maintenance
- Cleaning: Wipe the main unit and outdoor sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries in both units when the low battery indicator appears on the display. Ensure correct battery type and polarity.
- Outdoor Sensor: Periodically check the rain funnel for debris (leaves, insects) and clean as necessary to ensure accurate rainfall measurement. Ensure the wind cups and vane spin freely.
- Storage: If storing the unit for an extended period, remove all batteries to prevent leakage.
7. Troubleshooting
- No Outdoor Data Displayed:
- Check if the outdoor sensor batteries are correctly installed and charged.
- Ensure the outdoor sensor is within the 100m transmission range of the main unit and there are no major obstructions.
- Try re-synchronizing the units (refer to the full manual for specific steps).
- Inaccurate Readings:
- Temperature/Humidity: Ensure the sensor is not in direct sunlight or near heat sources.
- Rainfall: Check the rain funnel for blockages. Ensure the sensor is level.
- Wind: Ensure wind cups and vane are free to move and not obstructed.
- Display Not Lighting Up (Battery Power): The backlight is designed to illuminate for 15 seconds when powered by batteries to conserve energy. For continuous backlight, use the USB power cable.
