5、NFORMATION LABEL CHECK (for YPWXJ type) Additional Laser Caution 1.Laser Interlock Mechanism The position of the switch (S9501) for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (S9501) is pressed physically. Thus, t

6、he interlock will no longer function if the switch (S9501) is released physically and deliberatery. The interlock also does not function in the test mode . Laser diode oscillation will continue, if pin 1 of CXA1821M (IC8101) on the CD ASSY mounted on the $M Loading Mechanism assembly is connected to

7、 GND, or else the terminals of Q8101 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. : Refer to page 61 on the service manual RRV2328.

9、NEOUS PARTS 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. Screws adjacent t

10、o mark on product are used for disassembly. Reference Nos. indicate the pages and Nos. in the service manual for the base model. NOTES: 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

11、from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%).
