• Precautions on Class 2 Laser Product
- Do not stare into the direct or specularly reflected beam.
- Do not direct the beam at people or into areas where people
might be present.
- Be careful of the path of the laser beam.
If there is a possibility that the operator may be exposed to the
specular or diffuse reflections, block the beam by installing a
protective enclosure.
- Install this product so that the path of the laser beam is not as the
same height as that of human eye.
• Precautions on Class 1 Laser Product
- Do not stare into the direct or specularly reflected beam.
