7.2.4 Alignment of the M4000 Advanced with integrated laser alignment aid
(optional)
WARNING
Never look directly into the laser beam!
If the laser beam falls on your eye, you must consciously close your eyes or turn away
immediately.
The multiple light beam safety device is equipped with an
integrated laser alignment aid of laser class 2. Brief action of
the laser beam (up to 0.25 s) is not dangerous for the eye.
Therefore, an ocular hazard can exist only if an individual
overcomes their natural aversion to bright light and stares
directly into the laser beam.
Do not point the laser at a person’s eye at close range.
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
The M4000 Advanced multiple light beam safety device is available with an integrated
laser alignment aid as an extra.
The laser alignment aid in conjunction with the indications on the 7@segment display
enables you to precisely adjust and align the multiple light beam safety device. The aid
comprises a laser per light beam (in the receiver) as well as a laser deflector mirror and a
transparent display screen (in the sender).
The laser alignment aid is activated automatically when the M4000 Advanced is switched
on if the light beams are not yet aligned or if the light path is interrupted.
