2. Safety Information
WARNING: LASER RADIATION. AVOID DIRECT EYE EXPOSURE.
This product emits laser radiation. Improper use or direct exposure to the laser beam can cause severe eye injury or blindness. Always adhere to the following safety precautions:
- Never look directly into the laser aperture or at the reflected beam.
- Use appropriate laser safety goggles when operating the module.
- Ensure the laser is pointed away from people, animals, and reflective surfaces.
- Keep out of reach of children.
- Do not disassemble or modify the laser module. Unauthorized modifications can lead to hazardous radiation exposure.
- Operate in a controlled environment where accidental exposure is minimized.

- Power Supply: Plug the 12V power adapter into a suitable wall outlet.
- Mounting (Optional): If permanent installation is required, the module can be mounted using the screw holes on its base. Refer to the "Specifications" section for mounting dimensions.
5. Operating Instructions
Once the module is set up, operation is straightforward:
- Power On: After connecting the power adapter to the module and plugging it into the wall outlet, the laser module will automatically power on and emit a green laser dot.
- Usage: Direct the laser dot to your desired target. Ensure no direct eye exposure occurs.
- Power Off: To turn off the laser, simply unplug the 12V power adapter from the wall outlet or disconnect the DC plug from the module.
Note on Continuous Operation: The module is equipped with a powerful heat sink fan for extended operation. However, to ensure optimal lifespan (rated at 8000 hours), it is recommended to rest the module for 1 minute after every 1 hour of continuous use.
6. Maintenance
Proper maintenance will help prolong the life and performance of your laser module:
- Cleaning: Keep the laser aperture and lens clean. Use a soft, lint-free cloth and, if necessary, a small amount of lens cleaning solution. Avoid abrasive materials that could scratch the lens.
- Heat Management: Ensure the heat sink fins and fan are free from dust and debris to allow for proper airflow and cooling. Periodically clean the fan blades gently with compressed air.
- Storage: When not in use, store the laser module in a cool, dry place, away from direct sunlight and extreme temperatures.
