Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm not sounding or unit not powering on. | Low or dead batteries; incorrect battery installation; unit not turned on. | Replace batteries with new AAA batteries, ensuring correct polarity. Long press the Power Button to turn on the unit. Ensure USB power is connected if not using batteries. |
| False alarms. | Movement from pets; drafts; direct sunlight; heat sources; unit placed too close to moving objects. | Adjust placement to avoid areas with pets or environmental factors. Ensure the detection window is clear. The PIR technology is designed to reduce false alarms from non-human motion. |
| Remote control not working. | Out of range; remote battery low; interference. | Move closer to the alarm unit (within 328ft/100m). Replace the remote control battery (typically a coin cell battery, not specified in JSON, so general advice). Ensure no major obstructions. |
| Alarm sounds continuously for 2 minutes. | This is normal behavior in Alarm Mode once triggered. | Disarm the alarm using the remote control. |
