1. SAFETY INFORMATION

This service manual is intended for qualified service technicians ; it is not meant for the casual do-it- yourselfer. 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
	Leakage	not be above
Device	current	0.5mA
under	tester
test
Test all
exposed metal
surfaces
Also test with
plug reversed		Earth
(Using AC adapter		ground
plug as required)

AC Leakage Test

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 on the schematics and on the parts list 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.

Additional Laser Caution

1.Laser Interlock Mechanism

The position of the switch (S101) on the LOAB Assy for detecting loading state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (S101) is not on TRAY terminal side (TRAY signal is OFF or high level.). Thus, the interlock will no longer function if the switch (S101) is

deliberately set to TRAY terminal side (low level).

The interlock also does not function in the test mode . Laser diode oscillation will continue, if pin 1 of CN101 on the CD-R CORE ASSY is connected to low level.

2.When the cover is opened with the servo mechanism block removed and turned over, close viewing of the objective lens with the naked eye will cause exposure to a Class 3 laser beam.

Refer to page 64.

Additional Laser Caution

1.Laser Interlock Mechanism

The position of the switch (S101) on the SELECT UNIT for detecting clamping state is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch (S101) is not on CLMP terminal side (CLMP signal is OFF or high level.). Thus, the interlock will no longer function if the switch (S101) is

deliberately set to CLMP terminal side (low level).

The interlock also does not function in the test mode . Laser diode oscillation will continue, if pin 9 of TA2150FN (IC1101) on the 3CD ASSY is connected to GND, or pin 26 is connected to low level (ON), or else the terminals of Q1101 are shorted to each other (fault condition).

2.When the cover is opened with the servo mechanism block removed and turned over, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam.

Refer to page 63.

How to Install the Disc Table

1 Use nippers or other tool to cut the two sections marked A in figure 1 .

2While supporting the spindle motor shaft with the stopper, put spacer on top of the carriage base, and stick the disc table on top (takes about 9kg pressure). Take off the spacer.
