4. Operating Instructions
The ProtectG AR39 features a PIR motion sensor that detects animals up to 26 feet away within a 110° angle. Upon detection, it activates ultrasonic sounds and/or flashing LED lights based on the selected mode.
4.1 Mode Selection
Use the 'Frequency' dial (labeled I-V) on the unit to select the desired operating mode:
| Mode | Description | Target Animals |
|---|---|---|
| 0 (OFF) | Device is turned off. | N/A |
| I | 18-25.5kHz ultrasonic sound + flashing LED lights. | Small animals (e.g., mice, rats, martens) |
| II | 20-35kHz ultrasonic sound + flashing LED lights. | Medium animals (e.g., cats, dogs, foxes) |
| III | 30-45kHz ultrasonic sound + flashing LED lights. | Large animals (e.g., deer, raccoons, birds) |
| IV | Strong flashing LED lights (15s quick flash, 5s slow flash). | Nocturnal animals |
| V | All functions working, cycling through Modes I, II, III, and IV. | Comprehensive deterrence |
4.2 Sensitivity Adjustment
Use the 'Sensitivity' dial (labeled MIN-MAX) to adjust the detection range of the PIR motion sensor:
- MIN: Shorter detection range.
- MAX: Longer detection range (up to 26 feet).

5. Maintenance and Charging
- Solar Charging: The integrated solar panel charges the internal 600mAh rechargeable battery during daylight hours. Ensure the solar panel is clean and free from obstructions (e.g., leaves, dirt) for efficient charging.
- USB Charging: If sunlight is insufficient or for a quicker charge, use the provided USB cable to charge the device. Connect the cable to the charging port at the bottom of the unit (under the rubber cover) and to a standard USB power adapter (not included). A full charge typically takes several hours.
- Cleaning: Wipe the device periodically with a soft, damp cloth to remove dirt and debris, especially from the solar panel and motion sensor. Do not use harsh chemicals or abrasive cleaners.
- Weather Resistance: The device is IP65 waterproof and heat-resistant, designed for year-round outdoor use. However, prolonged exposure to extreme weather conditions may affect battery performance.
6. Troubleshooting
If you encounter issues with your ProtectG Solar Ultrasonic Animal Repellent, please refer to the following common solutions:
- Device not activating:
- Ensure the device is turned on (Mode I-V selected).
- Verify the solar panel is receiving direct sunlight or charge the device via USB.
- Check that the motion sensor is not obstructed by plants or other objects.
- Adjust the sensitivity dial to 'MAX' to increase detection range.
- Animals not deterred:
- Try different operating modes (I-V) to find the most effective frequency for the specific target animal.
- Adjust the device's placement to ensure optimal coverage of the protected area.
- Ensure the device is not obstructed by dense foliage or objects that could block the ultrasonic waves.
- Consider using multiple units for larger or irregularly shaped areas.
- Short battery life:
- Ensure the solar panel is clean and exposed to direct sunlight for at least 6-8 hours daily.
- Fully charge the device via USB if solar charging is insufficient.
- Battery performance may be reduced in cold weather conditions.
