Image: Illustration of the weather station and sensor powered by either an AC adapter or AA batteries.
- For Outdoor Sensor: Open the battery compartment (C7) on the back of the wireless sensor. Insert 2 x AA batteries, observing the correct polarity (+/-). Close the compartment.
- For Main Unit: Open the battery compartment (B4) on the back of the main unit. Insert 2 x AA batteries, observing the correct polarity (+/-). Alternatively, connect the AC adapter to the power supply socket (B12) and plug it into a wall outlet.
- Note: If using only batteries for the main unit, the backlight will only illuminate temporarily for 15 seconds when a button is pressed. For continuous backlight, use the AC adapter.
5.2 Sensor Pairing
The main unit will automatically search for the outdoor sensor upon initial power-up. Ensure the sensor is within range (up to 60 meters / 200 feet in open air).
Image: The weather station and its outdoor sensor, demonstrating their wireless connection.
- Place the outdoor sensor near the main unit during the initial setup.
- Ensure the channel switch (C6) on the outdoor sensor is set to Channel 1 (default). If you have multiple sensors, set them to different channels (1, 2, or 3).
- The main unit will display outdoor temperature and humidity once connected. If connection fails, press and hold the "" button (B8) on the main unit for 3 seconds to initiate a manual search.
5.3 Initial Settings (Time, Date, City, Units)
The weather station supports DCF Radio Controlled Clock (RCC) function for automatic time synchronization in regions with DCF signal coverage (e.g., Europe).

- Time Synchronization (RCC): After power-up, the unit will automatically attempt to synchronize the time via the DCF signal. This process may take several minutes. The RCC icon will flash during synchronization and become solid once successful.
- Manual Time/Date Setting: If RCC is not available or desired, press and hold the "" button (B9) to enter time setting mode. Use the "▲/" (B7) and "▼" (B6) buttons to adjust values, and "" (B9) to confirm and move to the next setting (Time Zone, 12/24H format, Hour, Minute, Year, Month, Day, Temperature Unit °C/°F, Pressure Unit hPa/inHg).
- City Selection: Press the "" button (B10) to select your city. This affects sunrise/sunset times and tide information. Use "▲/" (B7) and "▼" (B6) to navigate through cities.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit | No power or dead batteries. | Connect AC adapter or replace AA batteries in the main unit. |
| Outdoor temperature/humidity not displayed | Sensor out of range, dead sensor batteries, or interference. | Move sensor closer to main unit. Replace sensor batteries. Press and hold "" button (B8) on main unit to re-establish connection. Avoid placing near large metal objects or electronics. |
| Incorrect time/date | RCC signal not received or manual settings incorrect. | Ensure unit is in an area with good RCC reception. Manually set time and date if RCC signal is weak or unavailable. |
| Weather forecast inaccurate | Weather forecasts are based on atmospheric pressure changes and are predictive, not absolute. | This is normal. The forecast provides a general trend for the next 12 hours. |
| "LL.L" or "HH.H" displayed | Temperature or humidity is outside the measurable range. | Move the unit or sensor to an environment within the specified operating range. |
