- Additional Laser Caution

1. Laser interlock Mechanism
The position of the switch (8601) for detecting loading
state is detected by the system microprocessor. and
the design prevents laser diode oscillation when the
switch (8601) is not on CEMP terminal side (CEMP
signal is OFF or high level).
Thus. the interlock will no longer function if the switch
(8601 )is deliberately set to DEW terminal side (low level).
The interlock also does not function in the test mode *.
Laser diode oscillation will continue. if pin 1 of
M51598FP (ICiOi) on the PRE AMP BOARD ASSY
I mounted on the pickup assembly is connected to GND.
or pin 19 is connected to low level (ON). or else the
ADVARSEI. CAUTION 5 terminals of 0101 are shorted to each other (fault
