General notes
WARNING - RISK OF LASER RADIATION
This instrument is a class 4 laser device. For this reason, the operator must
take precautions to prevent injuries or damage. Applicable national and
international regulations must be observed.
Use the lowest possible power necessary to achieve the desired effect.
Focus the aiming beam as carefully as possible on the tissue to be treated.
Never trigger the laser if the aiming beam is not clearly visible in the target
area.
Deactivate the treatment beam and always switch the aiming beam off
before changing the applicator or releasing the applicator fibers from the
laser module for any other reason (Please note that incorrect release of the
fibers when the laser is in operation may result in a brief discharge of
scattered radiation to the surroundings.).
Switch the aiming beam off when the instrument is not in use.

Because the aiming beam follows the same optical path through
the beam delivery system as the therapy beam, it represents a
good method for checking that the beam delivery system is
undamaged. If the aiming beam spot at the distal end of the beam
delivery system is not visible, is weak or appears diffuse, it may
indicate damage to or improper function of the beam delivery
system.
