4. Operating Instructions
The night light features a multi-function button for controlling its various modes.
4.1 Mode Selection
The device has three primary modes:
- Induction Mode (Motion Sensor): In dark environments, the light will automatically turn on when it senses human presence and turn off when people leave. This mode is highly sensitive with a 0-second response time, a 120° wide-angle induction, and an effective distance of 3-6 meters.
- Normally On Mode: The light remains continuously on.
- Flashlight Mode: The top light functions as a focused flashlight.

- Press 1 time: Activates the top flashlight mode.
- Press 2 times: Turns off the flashlight and turns on the night light (main panel light).
- Press 3 times: Turns off the night light and activates the top flashlight in a flashing (rescue) mode.
- Press 4 times: Enters human body induction mode (motion sensor).
- Long press for 2 seconds: The light will flash twice, and the product will power off.

5. Maintenance
- Cleaning: Wipe the surface of the night light with a soft, dry cloth. Do not use abrasive cleaners or immerse the device in water.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Recharge when the battery indicator shows low power.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures.
6. Troubleshooting
- Light not turning on:
- Ensure the device is charged.
- Check if it is in the correct operating mode (e.g., Induction Mode requires darkness and motion).
- If using the plug-in base, ensure the base is properly inserted into a working power outlet.
- Motion sensor not responding:
- Verify the device is in Induction Mode.
- Ensure there are no obstructions blocking the sensor.
- Confirm the ambient light is dark enough for the sensor to activate.
- Short battery life:
- Ensure the device is fully charged.
- Frequent use of the 'Normally On' or 'Flashlight' modes will consume battery faster than 'Induction Mode'.
