— Additional Laser Caution
1. The ON/OFF statuses of the side-A/B detection switch
( TURN switch on the TNSB assy ), slider-position detection
switches (INNER and OUTER on the PKSB assy) and
loading-status detection switches (SW 1, 2 and 3 on the
LMSB assy ) are detected by the microprocessor (1C101 in
the MOTHER assy ). To permit the laser diode to oscillate, it
is required to set the side-A/B detection switch for side A
status (TRN : OFF) and the slider-position detection
switches for the LD ACTIVE status (INNER : OFF, OUTER:
OFF), and to set the loading-status detection switches for tilt
neutral state (SW1: OFF, SW2 : OFF, SW3 : ON). As lang
as these requirements are not satisfied, the laser diode will
not oscillate. When the requirements are met in any way, the
laser diode can oscillate. The laser diode oscillation will
continue if pin 13 of IC801 is shorted to GND or the emitter
and collector of Q834 are shorted each other (fault
condition ) in MOTHER assy.
In the test mode * , the laser diode oscillates when the
microprocessor detects a PLAY signal, or when the PLAY
key is pressed (S106 ON in the FLKY assy for CLD - D790
or S206 ON in the KEYB assy for CLD - D590 and CLD -
D396), 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 a Class 1
laser beam.
* : Refer to pages 58 and 59.
