Battery Replacement
When the sensor batteries are low, the receiver will indicate a low battery alert. Replace the 4 AA 1.5V alkaline batteries in the affected sensor promptly to ensure continuous operation.
Troubleshooting
False Alarms
If you experience frequent false alarms, consider the following:
- Adjust Sensitivity: Lower the sensitivity setting of the sensor from 30ft to 15ft.
- Reposition Sensor: Ensure the sensor is not directly facing sunlight, heat sources, or areas with dense foliage that might sway in the wind. Mounting it higher can also help avoid small animals.
No Connection Between Units
If a sensor is not connecting to the receiver:
- Check Batteries: Ensure the sensor has fresh batteries and they are installed correctly.
- Power Cycle: Turn off and on both the receiver and the sensor.
- Range: Verify that the sensor is within the effective range of the receiver, considering any obstructions.
