Product Overview
Main Display Unit
- LCD Display: Shows time, date, indoor temperature, outdoor temperature, and various indicators.
- SET Button: Used for entering settings mode and adjusting values.
- MIN/MAX/+ Button: Used to view minimum/maximum temperature records and adjust values in settings mode.
- Battery Compartment: Located on the back, for 2x AA 1.5V batteries.
Wireless Outdoor Sensor
- Temperature Sensor: Measures outdoor temperature.
- Transmission Indicator: A small LED that flashes during data transmission.
- Battery Compartment: For 2x AA 1.5V batteries.
Setup
1. Battery Installation
- Open the battery compartment of the wireless outdoor sensor. Insert 2x AA 1.5V batteries, observing the correct polarity (+/-). Close the compartment.
- Open the battery compartment of the main display unit. Insert 2x AA 1.5V batteries, observing the correct polarity (+/-). Close the compartment.
Note: It is recommended to insert batteries into the outdoor sensor first to ensure proper synchronization.
2. Sensor Placement
- Place the outdoor sensor in a shaded, dry location, protected from direct rain, snow, and direct sunlight.
- Ensure the sensor is mounted vertically to prevent water from entering the battery compartment.
- The maximum transmission range is 100 meters in an open field. Walls, metal structures, and electronic devices can reduce this range.
- Position the main unit indoors, away from large metal objects or other electronic devices that might cause interference.
3. Initial Synchronization
After battery installation, the main unit will automatically search for the outdoor sensor signal and the radio-controlled time signal. This process may take several minutes. Once synchronized, the outdoor temperature and the precise time/date will appear on the display.

When the low battery indicator appears on the display, replace all batteries in both the main unit and the outdoor sensor. Ensure correct polarity. Dispose of old batteries responsibly according to environmental regulations.
Storage
If the device will not be used for an extended period, remove the batteries from both units to prevent leakage and damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No outdoor temperature display | Outdoor sensor out of range, low batteries, interference. | Check/replace sensor batteries. Reposition sensor closer to main unit. Ensure no major obstructions or electronic interference. |
| Incorrect time display | Poor radio signal reception, incorrect time zone. | Move main unit to a location with better radio signal reception (e.g., near a window). Check and adjust the time zone setting. |
| Display is blank or dim | Low or depleted batteries. | Replace all batteries in the main unit. |
