WARNINGS
1.
Laser radiation
The Laser Detection Unit (LDU)
in
the optical deck has
been equipped with a semiconductor laser. This laser
emits
invisible light which
is
focussed on the disc
the objective.
If the objective would
be
removed
in
case of repair,
the laser light exits from the objective aperture. Avoid
looking directly into the laser beam, as this might
cause permanent injury to the eye.
2.
Replacement of modules
Before replacing a module upon repair, first the mains
switch should
be
switched off. This should
be
done to
prevent damage to the circuits on the modules.
