Additional Laser Caution

1. Laser Interlock Mechanism
The position of the switch ($501) Ior detecting loading
state is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch
(560]) is not on m terminal side (CLMP signal is OFF
or high level.). Thus. the interlock will no longer function H
the switch ($601) is deliberately set to W terminal
side (low level).
The interlock also does not lunction in the test mode it .
Laser diode oscillation will continue. ll pin 1 of M51953FP
(lClOl) on the PRE AMP BOARD ASSY mounted on the
pickup assy is connected to GND. or pin 19 is connected
to low level (ON). or else the terminals of 0101 are

L AS 1 shmted to each other (tault condition).

LASER PRODUCT 2, When the cover is opened with the servo mechanism

van-m block removed and turned over. close viewing at the
objective lens with the naked eye will cause exposure to a
Class 1 laser beam.
