Setup
1. Battery Installation
The Raddy R4 sensor requires two (2) AA batteries (not included). For optimal performance, especially in cold environments (below -10 °C), it is recommended to use low-temperature resistant batteries.
- Locate the battery compartment on the back of the sensor.
- Slide open the battery cover.
- Insert two AA batteries, ensuring correct polarity (+ and -).
- Close the battery cover securely.

2. Pairing with Main Unit (WF-80C)
To ensure proper synchronization, always insert batteries into the main WF-80C unit before installing batteries in the R4 remote sensor.
- Ensure your Raddy WF-80C weather station is powered on.
- Install batteries into the R4 sensor as described above. The sensor will automatically attempt to pair with the main unit.
- Allow a few minutes for the sensor to establish a connection. Once connected, the temperature and humidity readings will appear on the main unit's display.
3. Mounting and Placement Recommendations
The Raddy R4 sensor offers versatile mounting options and can be placed on a shelf or hung on a wall using the integrated keyhole slot on its back.
Figure 3: Rear view of the Raddy R4 sensor, highlighting the mounting features.
For accurate readings and optimal wireless transmission, observe the following placement guidelines:
- Position: Place the remote sensor in a vertical position.
- Airflow: Position it in an area with free air circulation, ideally with a shelter to protect it from direct elements.
- Interference: Keep it away from potential interfering sources such as large metal objects, electronic devices, or thick walls that can obstruct the wireless signal.
- Height: For outdoor use, place the sensor at least 47 inches (1.2 meters) from the ground.

Operating Instructions
1. LCD Display
The R4 sensor features a clear digital LCD display that shows the current channel number, temperature, and humidity. It supports both Celsius (℃) and Fahrenheit (℉) temperature units.

2. Wireless Transmission
The sensor transmits data wirelessly to the main WF-80C unit. The wireless transmission range is up to 100 meters (approximately 328 feet) in an open area. Obstacles such as walls, metal structures, and electronic interference can reduce this range.
Maintenance
1. Battery Replacement
When the battery indicator on the main unit or the sensor's display shows low power, replace both AA batteries promptly to ensure continuous operation and accurate readings. Follow the battery installation steps in the Setup section.
2. Cleaning
Wipe the sensor with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
3. Environmental Considerations
While the sensor is designed for outdoor use, prolonged exposure to extreme weather conditions (e.g., heavy rain, direct sunlight, or temperatures significantly outside its operating range) can affect its lifespan and accuracy. Ensure it is placed under a shelter if used outdoors.
