Operating Instructions
The iMaihom motion sensor light offers multiple operating modes and adjustable settings located on the bottom of the motion sensor unit.
Control Dials:
- TEST Mode (Left Dial): Used for initial setup and testing. In this mode, the light will turn on for 5 seconds when motion is detected, regardless of ambient light.
- TIME (Middle Dial): Adjusts the duration the light stays on after motion is detected, ranging from 10 seconds to 10 minutes.
- SENSITIVITY (Right Dial): Controls the detection range of the motion sensor (L: 19-26.2ft, M: 26.2-39.3ft, H: 39.3-72ft). Adjust this to prevent false triggers from small animals or distant objects.
Operating Modes:
- Motion Sensor Mode: The light activates only when motion is detected in dark conditions. The duration and sensitivity are set by the TIME and SENSITIVITY dials.
- Dusk to Dawn Mode (D2D): The built-in photocell sensor automatically turns the light ON when ambient light levels fall below a certain threshold (dusk) and OFF when light levels rise (dawn). Motion detection is typically overridden or integrated based on specific settings.

Maintenance
- Cleaning: Clean the fixture with a soft, damp cloth. Do not use abrasive cleaners or solvents.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power, incorrect wiring, or sensor settings. | Check circuit breaker. Verify wiring connections. Adjust sensor settings (e.g., ensure not in TEST mode if expecting D2D). |
| Light stays on constantly. | Continuous motion detected, or D2D mode active during daylight. | Check for obstructions in sensor's field of view. Adjust SENSITIVITY dial. Ensure D2D mode is set correctly for ambient light. |
| Motion sensor is too sensitive/not sensitive enough. | SENSITIVITY dial setting. | Adjust the SENSITIVITY dial to 'L' for less sensitivity or 'H' for more sensitivity. |
| Light flickers. | Loose wiring connection. | Turn off power and check all wire connections for tightness. |
