1. SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-ityourselfer. 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.

WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause cancer, birth defects or other reproductive harm.

Health & Safety Code Section 25249.6 – Proposition 65

NOTICE (FOR CANADIAN MODEL ONLY) Fuse symbols (fast operating fuse) and/or (slow operating fuse) on PCB indicate that replacement parts must be of identical designation.

REMARQUE (POUR MODÈLE CANADIEN SEULEMENT) Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les pièces de remplacement doivent avoir la même désignation.

(FOR USA MODEL ONLY)

1. SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester such as Simpson Model 229-2 or equivalent between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal overlays, control shaft, etc.). Plug the AC line cord of the appliance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA.

Reading should not be above

0.5mA

Earth ground

Device under test

Also test with plug reversed (Using AC adapter plug as required)

Leakage current tester

Test all exposed metal surfaces

ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in the appliance have special safety related characteristics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this Service Manual. Electrical components having such features are identified by marking with a in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest information, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Service Manual may be obtained at a nominal charge from PIONEER.

IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON.

LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 5 mW WAVELENGTH: 760 - 800 nm

LABEL CHECK (For MYXCN and NVXCN Types)

XR-MT3

Additional Laser Caution

1.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.

2. EXPLODED VIEWS AND 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.

Screws adjacent to mark on the product are used for disassembly.

5. 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

47k Ω→47 × 103→ 473 ........................................................RD1/4PU 4 7 3 J

0.5 Ω→R50 ..................................................................................... RN2H

1 Ω→1R0 ..................................................................................... RS1P

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

5.62k Ω→ 562 × 10
