The main unit features a large LCD display divided into several sections:
- Weather Forecast: Displays upcoming weather conditions with symbols (e.g., sun, clouds, rain).
- Outdoor Data: Shows current outdoor temperature and humidity received from the wireless transmitter.
- Indoor Data: Displays current indoor temperature and humidity.
- Atmospheric Pressure: Current pressure value and a bar graph showing the pressure trend over the last 12 hours.
- Time & Date: Radio-controlled time, date, and day of the week.
- Moon Phase: Current moon phase symbol.
- Touch Buttons: Located below the display for settings and backlight activation.
3.2 Main Unit (Rear)

The rear of the main unit includes the battery compartment and keyholes for wall mounting. A fold-out stand is also present for tabletop placement.
3.3 Wireless Outdoor Transmitter

The outdoor transmitter measures external temperature and humidity and sends this data wirelessly to the main unit. It features a small display to show its current readings and a channel selection switch inside the battery compartment.
4. Setup
4.1 Battery Installation
The weather station requires 5 AAA batteries (not included): 3 for the main unit and 2 for the outdoor transmitter.
- Outdoor Transmitter: Open the battery compartment on the back of the outdoor transmitter. Insert 2 AAA batteries, observing the correct polarity (+/-). Close the compartment.
- Main Unit: Open the battery compartment on the back of the main unit. Insert 3 AAA batteries, observing the correct polarity (+/-). Close the compartment.
Upon battery insertion, the main unit will power on and begin searching for the outdoor transmitter signal and the radio-controlled time signal.
4.2 Placement of the Outdoor Transmitter
For accurate readings, place the outdoor transmitter in a protected location, away from direct sunlight and precipitation. Ensure it is within the wireless range of the main unit (typically up to 100 meters in open areas, less with obstacles).
4.3 Initial Synchronization
After installing batteries in both units, the main unit will automatically attempt to connect with the outdoor transmitter. This process may take a few minutes. Once connected, the outdoor temperature and humidity will appear on the main unit's display. If no signal is received, ensure both units are within range and try pressing the 'TX' button on the outdoor transmitter or initiating a manual search on the main unit (refer to the Operating section).
4.4 Radio-Controlled Time Reception
The weather station automatically sets its time and date via a radio signal. This process typically occurs within a few minutes or hours, depending on signal strength. Place the main unit away from electronic devices that might cause interference. If the time does not set automatically, you may need to manually set it (refer to the Operating section).
5. Operating the Weather Station
5.1 Display Information
The display provides a comprehensive overview of current conditions:
- Weather Forecast: Symbols indicate predicted weather (e.g., sunny, partly cloudy, rainy). This forecast is based on atmospheric pressure changes.
- Outdoor Temperature/Humidity: Current readings from the outdoor sensor. A trend arrow may indicate rising or falling values.
- Indoor Temperature/Humidity: Current readings from the main unit's internal sensors.
- Atmospheric Pressure: Current pressure in hPa and a bar graph showing the pressure history over the last 12 hours.
- Time/Date/Day: Radio-controlled time, date, and day of the week.
- Moon Phase: A graphical representation of the current moon phase.
5.2 Touch Buttons
The weather station features touch-sensitive buttons on the front for various functions. Specific functions may vary, but generally include:
- Backlight: Pressing a button (often indicated by a light bulb or similar icon) activates the display backlight for a few seconds.
- Settings/Mode: Used to enter settings mode or cycle through display modes (e.g., min/max values).
- Adjust (+/-): Used to adjust values in settings mode.
- Channel: If multiple outdoor sensors are connected, this button cycles through their readings.
- Alarm: To set or activate/deactivate the alarm.
5.3 Alarm Function
The weather station includes an alarm clock with two programmable alarm times and a snooze function. Refer to the detailed instructions in the full manual for setting specific alarm times and activating snooze.
5.4 Connecting Additional Sensors
The main unit can connect with up to two additional wireless outdoor transmitters (sold separately). To connect additional sensors, ensure each sensor is set to a different channel (e.g., Channel 1, 2, or 3) using the switch inside its battery compartment. The main unit will automatically detect and display data from all active sensors within range.
5.5 Adjusting Atmospheric Pressure
The atmospheric pressure reading can be calibrated for local conditions. Access the settings menu (usually by holding down a 'SET' or 'MODE' button) and navigate to the pressure adjustment option. Consult a local weather service or another calibrated barometer for the correct local pressure value to ensure accurate weather forecasts.
6. Maintenance
6.1 Battery Replacement
Replace batteries in both the main unit and outdoor transmitter when the low battery indicator appears on the display. Always replace all batteries in a unit at the same time with new ones of the same type. Ensure correct polarity.
6.2 Cleaning
Clean the weather station and outdoor transmitter with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the display or casing. Avoid exposing the units to excessive dust or dirt.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No outdoor temperature/humidity displayed. | Outdoor transmitter out of range, low batteries, or interference. | Check battery levels in the transmitter. Move transmitter closer to the main unit. Ensure no large metal objects or strong electronic devices are between them. Press the 'TX' button on the transmitter or initiate a manual search on the main unit. |
| Incorrect time/date. | Radio signal interference or weak signal. | Move the main unit to a location with better reception, away from electronic devices. Allow time for signal acquisition. If necessary, set time/date manually. |
| Weather forecast seems inaccurate. | Weather forecasts are based on atmospheric pressure trends and are not always 100% accurate for immediate conditions. Initial calibration of atmospheric pressure may be needed. | Allow the station to collect pressure data for 24-48 hours for better accuracy. Calibrate the atmospheric pressure if possible (see Operating section). Understand that it provides a tendency, not a precise forecast. |
| Display is difficult to read from certain angles. | LCD displays can have limited viewing angles. | Adjust the viewing angle of the main unit. Position it at eye level for optimal visibility. |
| Sensors show slight deviations or take long to adapt. | Normal for some sensors to have minor variations or require time to stabilize after changes in environment. | Allow up to 3 hours for values to stabilize after initial setup or significant environmental changes. Minor deviations are often within tolerance. |
| Interference with another weather station. | Two devices operating on the same frequency. | Change the channel of your outdoor sensor (and any additional sensors) to avoid conflicts. Reset the main unit and re-establish connection with your specific sensor. |
