Additional Laser Caution
1. Laser Interlock Mechanism
If the switch to detect door-open state (S603: DISC OPEN DET)
is open, the laser interlock mechanism operates and shuts down
the power source (Q100) to the laser diode drive circuit. The
system microcomputer detects this condition and does not issue
the Laser On command.
If Q100 is defective, accompanying a short-circuit between the
emitter and the collector, the system microcomputer judges this
status as the door-open state, and it does not issue the Laser
On command as long as Q611 is not defective, even if S603 is
open.
Therefore, the laser does not light unless S603 is intentionally
short-circuited in door-open state.
To light the laser in Test mode, short-circuit S603.
Hold S603 in the depressed position from the top, as it is a push
switch.
2. NEVER directly look at the objective lens from a short distance
when lighting the laser by short-circuiting S603 in door-open state.
