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. 1. SAFETY INFORMATION LABEL CHECK 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, the 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 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. IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON.

CONTRAST OF MISCELLANEOUS PARTS j p f y For the applying amount of lubricants or glue, follow the instructions in this manual. (In the case of no amount instructions, apply as you think it appropriate.) 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 to 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 from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). 560 Ω → 56 × 10 1 → 561 ........................................................ RD1/4PU 5 6 1 J 47k Ω → 47 × 10 3 → 473 ........................................................ RD1/4PU 4 7 3 J 0.5 Ω → R50 ..................................................................................... RN2H R 5 0 K 1 Ω → 1R0 ..................................................................................... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k Ω → 562 × 10 1 → 5621 ......................................................
