Possible
causes
The cause is an internal error in the combiner module.
Analysis / trou-
bleshooting
ð Using the guide laser, check whether the internal optics of the
laser is damaged. To do this, switch on the guide laser and check
whether this is visible after the optics head.
The guide laser should show a round shape in the area of the focus. If the guide
laser is not visible or is poorly visible, this is an indication of damage to the internal
optic.
ð Follow the steps described in section Configuration menu
