IMPORTANT
THIS PIONNER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.

Additional Laser Caution
1. Inside detection switch (S201 on the INSB assy) and loadingstatus detection switch (S301 on the LOSB assy) are detected
by the microprocessor (IC501 in the DVDM assy).
• To permit the laser diode to oscillate, it is required to set the
inside detection switch for the inside position (S201 : ON) and to
set the loading-status detection switch for the clamp position (the
center terminal of S301 is shorted to +5V). The laser diode
oscillation will continue if pin 13 of IC101 is shorted to +5V (fault
condition) in the DVDM assy.
In the test mode ∗ , the laser diode oscillates when microprocessor detects a PLAY signal, or when the PLAY key is pressed
(S107 ON in the FLKB assy), with the above requirements satisfied.
2. When the cover is open, close viewing through the objective lens
with the naked eye will cause exposure to the laser beam.
