The device features three operating modes, selectable via the power button or remote control. Press the power button repeatedly to cycle through the modes.

Image: Illustration of the three selectable working modes for the alarm.
- Mode A (24H Motion Sensor Sound & Flash Alarm): The alarm will activate with both sound and strobe light whenever motion is detected, day or night.
- Mode B (Night Motion Sensor Sound & Flash Alarm): The alarm will activate with both sound and strobe light only when motion is detected during nighttime hours.
- Mode C (Night Sound & Flash Alarm Every 5 Minutes): The alarm will activate with sound and strobe light every 5 minutes during nighttime hours, regardless of motion detection. This mode is suitable for continuous deterrence.
The default alarm sounds are gunshot and dog barking. You can also set your own recording.
5.1. Custom Sound Recording
- Press the recording button once; the red LED light will illuminate.
- Speak into the microphone to record your desired sound or words.
- Press the recording button again to save the recording.
- The maximum recording time is 20 seconds. The device will automatically stop recording after 20 seconds.
- New recordings will overwrite previous content.
5.2. Volume Adjustment
Use the volume control knob on the unit or the volume buttons on the remote control to adjust the alarm's loudness. The alarm offers up to 130dB sound output.

6. Charging Methods
The ChunHee Solar Outdoor Motion Sensor Alarm is primarily solar-powered, but also supports DC charging.
- Solar Charging: The integrated solar panel charges the internal battery when exposed to sunlight. Charging efficiency may vary based on weather conditions and seasons. For best results, ensure the device is placed in direct sunlight for more than 4 hours daily.
- DC Charging: For faster charging or during prolonged periods of low sunlight, use the provided USB cable with a DC5V ≤1A charger. The DC charge port is located on the rear of the unit.
The device is designed to work 24 hours a day, even in cloudy or rainy weather, by storing energy through weak sunlight. This eliminates the need for frequent battery replacement.
7. Maintenance
- Cleaning: Regularly wipe the solar panel with a soft, damp cloth to remove dust, dirt, or debris that may hinder charging efficiency.
- Battery: The device uses a built-in rechargeable battery. No user replacement is required under normal operating conditions.
- Remote Control Battery: If the remote control becomes unresponsive, replace its internal battery. Remember to remove the battery isolation piece from the bottom of the remote before first use.
- Placement: Ensure the PIR sensor is not obstructed by foliage or other objects that could cause false triggers or block detection.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not turning on or holding charge. | Insufficient solar charging; low battery. | Ensure the solar panel receives direct sunlight for several hours. Use DC charging via USB cable to fully charge the device. |
| Motion sensor not triggering alarm. | Incorrect mode selected; sensor obstructed; object out of range. | Verify the device is in Mode A or Mode B. Clear any obstructions from the PIR sensor. Adjust placement to ensure target is within 5-8 meter range and 110° angle. |
| Alarm sound is too low or not playing. | Volume set too low; sound switch off. | Adjust the volume using the control knob or remote. Check the sound switch setting. |
| Remote control not working. | Battery isolation tab still in place; remote battery depleted. | Remove the plastic isolation tab from the remote's battery compartment. Replace the remote battery if necessary. |
| Animals not deterred immediately. | Animals may need time to adapt to the deterrent. | Some animals may not respond immediately; it may take between two and four weeks to see results. Ensure proper placement and consistent operation. |
