4. Setup and Installation
4.1 Initial Charging
Before first use, it is recommended to fully charge the alarm. You can do this via:
- Solar Charging: Place the alarm in direct sunlight for 4-6 hours. The solar panel will automatically charge the internal battery.
- USB Charging: Connect the provided USB charging cable to the alarm's charging port and a 5V USB power adapter (not included). The charging indicator light will illuminate and turn off when fully charged.

This image shows the two charging methods for the alarm. On the left, an alarm is mounted on a wooden post in a sunny field, labeled 'Solar charging,' indicating it's installed outdoors and charged by sunlight. On the right, the back of the alarm is shown connected to a wall adapter via a USB cable, labeled 'DC charging,' explaining that direct current can be used for charging on rainy days to ensure continuous power.
4.2 Mounting Location
Choose a location that receives ample direct sunlight for optimal solar charging. Consider the following:
- Height: Mount the alarm at an adjustable height between 1 to 8 feet (0.3 to 2.4 meters) for best detection results.
- Detection Area: Ensure the motion sensor has a clear line of sight to the area you wish to protect, within its 125° sensing angle and 5-8 meter range. Avoid obstructions like dense foliage or large objects.
- Stability: Choose a stable surface such as a post, fence, tree, or wall.
4.3 Installation Steps
- Mark the desired mounting points on the surface using the alarm's mounting holes as a template.
- Drill pilot holes if necessary.
- Secure the alarm to the surface using the provided screws and wall anchors.
- Ensure the solar panel faces upwards to maximize sun exposure.

- Check Mounting: Occasionally inspect the mounting to ensure the alarm remains securely fastened and properly positioned.
- Battery Life: The internal battery is designed for long-term use. If you notice a significant decrease in performance, ensure the unit is receiving adequate sunlight or try a full USB charge.
7. Troubleshooting
If you encounter issues with your Comboss Solar Motion Sensor Alarm, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm not activating or low sensitivity. | Insufficient charge; sensor obstructed; incorrect mode; detection range too far. | Ensure full charge (solar or USB). Clean sensor lens. Verify correct operating mode (A or C for sound/flash). Adjust mounting height or location to be closer to detection area. |
| Alarm not charging. | Insufficient sunlight; dirty solar panel; faulty USB cable/adapter. | Relocate to an area with more direct sunlight. Clean the solar panel. Try charging via USB with a different cable/adapter. |
| Alarm sounds too often (false alarms). | Sensor too sensitive; positioned near moving objects (e.g., swaying branches, pets). | Adjust the alarm's position to avoid areas with frequent, non-threatening motion. Consider using Mode B or D (flash only) if sound is too disruptive. |
| Remote control not working. | Remote battery low/dead; out of range; interference. | Replace the remote control battery (AAA). Ensure you are within effective range of the alarm. Reduce potential interference. |
