Laser Interlock Mechanism The position of the switch for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch is pressed physically. Thus, the interlock will no longer function if the switch is released physically and deliberatery. Laser diode oscillation will continue, if pin 46 of TA2065F (IC2) on the CD SERVO PCB ASSY is connected to GND, or else the terminals of Q1 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. LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 5 mW WAVELENGTH: 760 - 800 nm IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON. LABEL CHECK 1.

PCB PARTS LIST 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. •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 ......................................................
