- Open the cover by twisting or sliding it according to the markings.
- Insert the required batteries (e.g., AAA or AA, refer to the compartment markings for correct type and polarity). Ensure correct polarity (+/-).
- Close the battery compartment cover securely.
4.2 Mounting the Night Light
The Bytech Motion Sensor Night Light offers versatile mounting options:
- Magnetic Mount: The night light features a built-in magnet. Simply attach it to any metallic surface. For non-metallic surfaces, use the included magnetic mounting plate. Peel off the adhesive backing from the plate and firmly press it onto a clean, dry surface. Then, attach the night light to the magnetic plate.
- Wall Mount: If the magnetic plate is not suitable, the night light may have keyhole slots for screw mounting. (Screws and anchors typically not included).

Recommended Placement: For optimal performance, place the night light in areas where motion detection is desired, such as hallways, stairwells, closets, bathrooms, or entryways. Avoid placing it near heat sources, direct sunlight, or in areas with high humidity.
5. Operating Instructions
The Bytech Motion Sensor Night Light is designed for automatic operation:
- Automatic Activation: Once batteries are installed and the night light is placed, it will automatically detect motion within its sensing range (up to 5 feet) in low-light conditions.
- Light On: When motion is detected in a dark environment, the night light will illuminate.
- Light Off: The light will automatically turn off after a short period (typically 15-30 seconds) if no further motion is detected.
- Daylight Sensor: The integrated daylight sensor prevents the light from activating during daytime or in brightly lit areas, conserving battery life.
6. Maintenance
6.1 Cleaning
To clean the night light, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water.
6.2 Battery Replacement
When the light output diminishes or the night light stops functioning, it is time to replace the batteries. Follow the battery installation steps outlined in Section 4.1.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | 1. Batteries are dead or incorrectly installed. 2. Ambient light is too bright. 3. No motion detected within range. | 1. Replace batteries, ensuring correct polarity. 2. Test in a darker environment. 3. Ensure motion occurs within 5 feet of the sensor. |
| Light stays on constantly. | 1. Continuous motion within sensing range. 2. Sensor obstruction or malfunction. | 1. Relocate the night light to an area with less constant activity. 2. Clean the sensor lens. If problem persists, contact support. |
| Motion sensor range is poor. | 1. Obstructions blocking the sensor. 2. Incorrect placement. | 1. Ensure a clear line of sight to the detection area. 2. Reposition the night light for optimal coverage. |
