7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on. | Low or dead batteries; incorrect battery installation; USB cable not connected properly. | Replace batteries, ensuring correct polarity. Check USB cable connection and power source. |
| No alert when motion is detected. | Sensor out of range; sensor angle incorrect; receiver volume too low; sensor or receiver OFF. | Ensure sensor and receiver are within 280m range. Adjust sensor angle. Increase receiver volume. Turn ON both devices. |
| False alarms. | Sensor detecting unintended movement (e.g., pets, wind, sunlight). | Adjust sensor angle and placement to focus on the desired detection area. Avoid direct sunlight. |
| Poor transmission range. | Obstructions (walls, metal objects); interference. | Relocate receiver and sensor to minimize obstructions. Avoid placing near large metal objects or other wireless devices. |
