Safety Precautions

• This is a Class IIIa laser product. Avoid direct eye exposure to the laser beam.
• Do not point the laser at reflective surfaces to prevent unintended reflections.
• Use appropriate laser safety goggles if necessary.
• Keep out of reach of children.

Troubleshooting

• Laser does not emit: Verify power supply voltage and connections.
• Weak or blurry line: Adjust the focus ring for optimal clarity.
• Module overheating: Ensure adequate heat dissipation and avoid prolonged continuous operation beyond specified limits.

Maintenance

• Keep the lens clean and free from dust or debris.
• Store the module in a dry environment to prevent corrosion.
• Periodically check connections and wiring for signs of wear or damage.
