1. SAFETY INFORMATION
This service manual is intended for qualified service technicians; it is not meant for the casual
do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been
trained to properly and safely repair complex products such as those covered by this manual.
Improperly performed repairs can adversely affect the safety and reliability of the product and may
void the warranty. If you are not qualified to perform the repair of this product properly and safely, you
should not risk trying to do so and refer the repair to a qualified service technician.
LABEL CHECK
1. Laser Interlock Mechanism
ON/OFF switching of the switch for detecting loadingstate,
ON/OFF switching of the clamp completion, close comple-tion
and shutter switches are detected by the system micropro-
cessor. The design of this interlook mechanism prevents
laser diode oscillation when even one of the clamp completion,
close completion and shutter switches is OFF (High level).
Accordingly, the interlock will no longer function and the
laserdiode will oscillater if all three of these switcher are set
deliber-ately to ON(Low level).
The interlock also does not function in the test mode ∗ .
Laser diode oscillation will continue, if pin 1 of M51593FP
(IC101) on the PRE AMP BOARD ASSY mounted on the
pickupassembly is connected to GND, or pin 19 is connected to
low level (ON), or else the terminals of Q101 are shorted to
each other (fault condition).
2. When the cover is opened, close viewing of the objective lens
with the naked eye will cause exposure to a Class 1 laser
beam.

NOTES : ÷Parts marked by “ NSP ” are generally unavailable because they are not in our Master Spare Parts List.
÷The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
÷Reference Nos. indicate the pages and Nos. in the service manual for the base model.
÷When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex. 1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by
J = 5%, and K = 10%).
560 Ω=56 ×101 =561................................................... RD1/4PU 561J
47k Ω=47 ×10 3=473 .................................................. RD1/4PU 473J
0.5 Ω=R50 ...................................................................... RN2H Â50K
1 Ω=1R0 ......................................................................... RS1P 1Â0K
Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω=562 ×10 1=5621 ........................................... RN1/4PC 5621F
