4. Setup
4.1 Power Supply
- Main Unit: Open the battery compartment on the back. Insert 3 x AAA batteries, observing the correct polarity (+/-). Alternatively, connect the supplied USB cable to the DC port on the back of the main unit and plug the other end into a USB power adapter (not included) or a USB port. The backlight will stay on continuously when powered by USB. When using batteries, the backlight illuminates for 10 seconds after a button press.
- External Sensor: Open the battery compartment. Insert 2 x AA batteries, observing the correct polarity (+/-).

4.2 Sensor Pairing
Once both the main unit and external sensor are powered on, they will automatically attempt to pair. Ensure the sensor is within range of the main unit. The main unit can connect to up to 3 external sensors. Use the channel switch inside the external sensor's battery compartment to select a channel (1, 2, or 3) if using multiple sensors or if pairing issues occur.

4.3 Initial Settings
After powering on, the unit will display default settings. Use the buttons on the back of the main unit to configure time, date, and other preferences.
- [SET] Button: Press to enter time/date setting mode. Press repeatedly to cycle through settings (Time Zone, 12/24H, Hour, Minute, Year, Month, Day, Language for Weekday, 0C/0F, Barometric Pressure Unit).
- [UP/MEM] Button: In setting mode, press to increase values. Outside setting mode, press to view MAX/MIN temperature/humidity records.
- [DOWN/CF] Button: In setting mode, press to decrease values. Outside setting mode, press to switch between 0C and 0F.
- [ALARM] Button: Press to view alarm time. Press and hold to enter alarm setting mode.
- [CHANNEL] Button: Press to switch between external sensor channels (CH1, CH2, CH3) if multiple sensors are connected.
- [ALERT] Button: Press to view temperature alert settings. Press and hold to enter alert setting mode.
- [SN/LIGHT] Button: Press to activate snooze during an alarm. Press to adjust backlight brightness (when USB powered) or activate backlight for 10 seconds (when battery powered).

5. Operating Instructions
5.1 Display Information
The main display is divided into several sections, providing a clear overview of all data:
- Top Section: Time, Date, Day of Week, Moon Phase, Alarm Status.
- Middle Section (Outdoor): Outdoor Temperature, Outdoor Humidity, Current Channel, Weather Forecast Icon, Barometric Pressure.
- Bottom Section (Indoor): Indoor Temperature, Indoor Humidity, MAX/MIN records indicator.
5.2 Weather Forecast
The weather station analyzes atmospheric pressure trends to predict weather for the next 12-24 hours. The forecast icons will change accordingly. For optimal accuracy, allow the unit to operate continuously for at least 72 hours to learn local pressure patterns.
5.3 Alarm and Snooze Function
To set the alarm, press and hold the [ALARM] button. Use [UP/MEM] and [DOWN/CF] to adjust the hour and minute. Press [ALARM] again to confirm. When the alarm sounds, press the [SN/LIGHT] button to activate the snooze function for 5 minutes. To stop the alarm, press any other button.

6. Maintenance
- Cleaning: Wipe the display and casing with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries in both the main unit and external sensor when the low battery indicator appears on the display. Ensure correct polarity.
- Sensor Placement: For optimal performance, place the external sensor in a shaded, dry location away from direct sunlight and rain. Avoid placing it near high-power electrical appliances or behind thick load-bearing walls, as these can interfere with wireless transmission.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Unit not powering on | Batteries are dead or incorrectly inserted; USB cable not connected or faulty. | Check battery polarity and replace if necessary. Ensure USB cable is securely connected to a working power source. |
| Outdoor temperature/humidity not displayed or inaccurate | Sensor out of range; sensor batteries low; interference; sensor not paired. | Move sensor closer to the main unit. Replace sensor batteries. Avoid placing near large metal objects or strong electromagnetic sources. Re-pair the sensor by re-inserting batteries in both units. |
| Inaccurate temperature/humidity readings (compared to other devices) | Sensor exposed to direct sunlight or heat source; unit needs time to stabilize. | Ensure sensor is in a shaded, well-ventilated area. Allow 1-2 hours for readings to stabilize after initial setup or relocation. Note that minor discrepancies between devices are normal. |
| Weather forecast seems incorrect | Unit has not completed its 72-hour learning period; local microclimates. | Allow the unit to operate for at least 72 hours for optimal forecast accuracy. The forecast is based on local atmospheric pressure changes and may not always match regional forecasts. |
| Backlight not staying on | Unit is running on batteries. | This is normal behavior for battery power to conserve energy. Connect the USB cable for continuous backlight. |
