Introduction
Usage
• Use laser enclosure device to prevent specular object from reflecting laser beam.
When used without an enclosure, be sure to avoid a laser path from eye level.
• Although the safety distance (NOHD) is approximately 1 m; it is advisable, however, to terminate the laser on its path
if possible. Nonreflective, flatting material is recommendable for termination.
• Wear protective glassed to protect against laser light during set up and adjustment.
