3. Setup
3.1 Battery Installation
- Main Unit: Open the battery compartment cover on the back of the main unit. Insert 2 AAA batteries (not included), ensuring correct polarity (+/-). Close the cover.
- External Sensor: Open the battery compartment cover on the back of the external sensor. Insert 2 AAA batteries (not included), ensuring correct polarity (+/-). Close the cover.
Note: It is recommended to insert batteries into the external sensor first, then into the main unit, to facilitate immediate pairing.
3.2 Sensor Placement
Place the external sensor in a sheltered outdoor location, away from direct sunlight and rain, to ensure accurate temperature and humidity readings. The maximum wireless range is typically up to 30 meters (100 feet) in open areas. Walls and other obstructions may reduce this range.

4. Operating Instructions
4.1 Initial Synchronization (Radio Controlled Clock)
Upon battery installation, the weather station will automatically attempt to synchronize with the DCF (or similar) radio signal to set the time and date. This process may take several minutes or up to 24 hours depending on signal strength. Ensure the unit is placed away from electronic interference.
- A signal icon will typically flash during synchronization and become solid once successful.
- If synchronization fails, try repositioning the unit or manually setting the time (refer to the device's physical buttons for manual setting instructions, if available).
4.2 Display Overview
The LED display shows the following information:
- Time: 12/24 hour format.
- Date & Day: Calendar display.
- Indoor Temperature & Humidity: Current readings from the main unit.
- Outdoor Temperature: Current reading from the external sensor.
- Weather Forecast: Icons indicating predicted weather conditions (e.g., sunny, cloudy, rainy).
4.3 Alarm Clock Function
The weather station includes an alarm clock function. Specific buttons for setting and activating the alarm are usually located on the back or top of the unit. Refer to the device's physical buttons and on-screen prompts for detailed alarm setting instructions.
4.4 Backlight LED Display
The unit features a backlight LED display for improved visibility in low light conditions. A dedicated button (often labeled "LIGHT" or "SNOOZE/LIGHT") typically activates the backlight temporarily or adjusts its brightness.
5. Features

- Check battery polarity and ensure batteries are fresh.
- Replace all batteries in both the main unit and external sensor.
- External Sensor Not Connecting:
- Ensure batteries are correctly installed in the external sensor.
- Place the external sensor closer to the main unit.
- Remove and reinsert batteries in both units to force a re-synchronization.
- Avoid placing the sensor near large metal objects or sources of electromagnetic interference.
- If the issue persists, the sensor might be faulty (refer to warranty information).
- Radio Controlled Clock Not Synchronizing:
- Ensure the unit is placed in an open area, away from electronic devices that may cause interference.
- Allow up to 24 hours for initial synchronization.
- Try repositioning the unit, especially near a window.
- Check if manual time setting is available as a temporary solution.
