1. SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-it­yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained
to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.

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

LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER : 7 mw
WAVELENGTH : 650 nm

LABEL CHECK

(Printed on the Rear Panel)

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.

∗ : Refer to page 40.
