Operating Instructions
The DEEIRAO Keyhole Motion Sensor LED Light operates automatically based on ambient light and motion detection.
- Automatic On/Off: The light will automatically turn on in dark environments when motion is detected. It will automatically turn off when strong light is present or after a period of no motion.
- Motion Sensor: The integrated PIR sensor detects human body movement within its range.
- Light Sensor: The light sensor ensures the unit only activates in low-light conditions, conserving battery life during the day.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | Insufficient darkness; batteries are dead or incorrectly installed; power switch is off. | Ensure the environment is dark enough for activation. Check battery orientation and replace if necessary. Verify the power switch is in the 'ON' position. |
| Motion sensor is not sensitive. | Strong ambient light interfering with the sensor. | The motion sensor is less sensitive in brighter conditions. Use the light in dark areas for optimal performance. |
| Light turns off too quickly. | Standard operating behavior. | The light is designed to turn off after a short period (typically 5-8 seconds) of no detected motion to conserve battery. |
