5. Setup
Follow these steps for initial setup:
- Power the Main Unit: Connect the provided DC adapter to the main weather station unit and plug it into a power outlet. The display will illuminate.
- Install Sensor Batteries: Open the battery compartment of the wireless outdoor sensor and insert 2 x AA batteries (not included), ensuring correct polarity. The sensor will automatically link with the main unit.
- Set Local Time: Press and hold the 'SET' button on the main unit for 3 seconds to enter time setting mode. Use the UP/DOWN buttons to adjust the time and 'SET' to confirm each setting (hour, minute, year, month, day).
Note: The device requires an adaptation period. Temperature and humidity readings will stabilize within 2 days, and weather forecasts will become accurate after 7 days of continuous operation.
6. Operating Instructions
6.1 Display Modes and Readability

6.4 Calibration Function
The weather station includes a calibration function to correct internal temperature, humidity, and atmospheric pressure data individually. Refer to the detailed user manual included in the box for specific instructions on accessing and adjusting calibration settings.
7. Maintenance
7.1 Battery Replacement
When the low battery indicator appears on the display for the outdoor sensor, replace the 2 x AA batteries. Ensure the main unit is powered by the DC adapter for continuous operation.
7.2 Cleaning
Wipe the display and unit surfaces with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the device.
8. Troubleshooting
- No outdoor sensor data: Ensure batteries are correctly installed in the sensor. Check that the sensor is within range of the main unit and not blocked by thick walls or metal objects.
- Inaccurate readings: Allow 2 days for temperature and humidity readings to stabilize. For weather forecasts, allow 7 days for the device to learn local atmospheric patterns. Use the calibration function if persistent discrepancies are observed.
- Display issues: Ensure the DC adapter is securely connected. Adjust backlight settings if the display is too dim or bright.
- Time not synchronizing: Ensure the main unit is placed in an area with good radio signal reception. Manual time setting is available if automatic synchronization fails.
