Additional Laser Caution

1. Laser Interlock MechanismThe position of the switch for detecting loading state isdetected by the system microprocessor, and the designprevents laser diode oscillation when the switch is pressedphysically.Thus, the interlock will no longer function if the switch is releasedphysically and deliberatery.Laser diode oscillation will continue, if pin 46 of TA2065F (IC2)on the CD SERVO PCB ASSY is connected to GND, or elsethe terminals of Q1 are shorted to each other (fault condition).

2. When the cover is opened, close viewing of the objectivelens with the naked eye will cause exposure to a Class 1laser beam.

LASER DIODE CHARACTERISTICSMAXIMUM OUTPUT POWER: 5 mWWAVELENGTH: 760 - 800 nm

IMPORTANTTHIS PIONEER APPARATUS CONTAINSLASER OF CLASS 1.SERVICING OPERATION OF THE APPARATUSSHOULD BE DONE BY A SPECIALLYINSTRUCTED PERSON.

5. PCB PARTS LISTNOTES:•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 × 101 → 561 ........................................................ RD1/4PU 5 6 1 J47k Ω → 47 × 103 → 473 ........................................................ RD1/4PU 4 7 3 J0.5 Ω → R50 ..................................................................................... RN2H R 5 0 K1 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 × 101 → 5621 ...................................................... RN1/4PC 5 6 2 1 F
