 Beam attenuator
When the laser beam may enter eyes during work, work with the beam
attenuator installed.
To attach the beam attenuator, fix
it with the attached screws in such
a manner as to cover the light
projection surface.
 Laser emission indicator
While the laser is emitted, the LED (green) on the sensor head goes on.
It is also possible to recognize the LED through the laser protective glasses.
