1. Laser Interlock Mechanism
Th6 ON/OFF {ON : low level, OFF : high lev€l) status of 3601 (LPS1}
and S602 (LPS2) switches for detecting rhe loading stat€ is detected
by the systern microprocessor, and the design prevents laser diode
oscillation except when borh switches (LPS1 and LPS2I are ON {low
level o. clampgd state).
Thus, interlock will no longer lunction it switches 360l {LPSI) and
S602 (LPS2) are d€liberat€lv shorted.
The int€rlock also does not oDerat€ in the t€st mode*.
Laser diode oscillation will continue. if pin 1 ot M51593FP {lC101)
on the PRE-AMP EOARD assembly loaded on pickup ass€mbly are
connected to GNO, or pin 19 is connected to low level {ON), or else
the terminal6 of O1O1 are shorted to each other lfault condition).
2. When the cover is opened with the servo mechanism block remov€d
and turn€d over, close viewing of the obj€ctive lens with the nakod
eye will caus€ €xposure to a Class 1 laser beam.

LASER PRODUCT
1. Laser Interlock Mechanism
The posilion of the switch (5601)for detecting loading srare is
detecred by the system microprocessor, and the design prevents
laser diode oscillation when the switch (5601) is not on CLMP
terminal side {CLMP signal is OFF or high level,}.
Thus, the interlock will no longer function if rhe switch (5601)is
deliberately set to CLMP terminal side. {low level).
The interlock also does not function in the test mode*.
Laser diode oscillation will continue, if pin 1 of M51593FP (lC1O1)
on the PRE-AMP BOARD ASSY mounted on the pickup assembty is
connected to GND, or pin 19 is connected to low level (ON), or else
the terminals of O1O1 are shorted to each other lfault condition).
2. When the cover is opened, close viewing of the objective lens with
the naked eve will cause exoosure to a Class 1 laser beam.
