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.

ANY MEASUREMENTS NOT WITHIN THELIMITS OUTLINED ABOVE ARE INDICATIVEOF A POTENTIAL SHOCK HAZARD ANDMUST BE CORRECTED BEFORE RETURN-ING THE APPLIANCE TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICEMany electrical and mechanical parts in the appliance

have special safety related characteristics. These areoften not evident f rom visual inspect ion nor theprotection afforded by them necessarily can be obtainedby using replacement components rated for voltage,wattage, etc. Replacement parts which have thesespecial safety character ist ics are ident i f ied in thisService Manual.

Electr ical components having such features areidentified by marking with a on the schematics andon the parts list in this Service Manual.The use of a substitute replacement component whichdoes not have the same safety characteristics as thePIONEER recommended replacement one, shown in theparts list in this Service Manual, may create shock, fire,or other hazards.

Product Safety is continuously under review and newinstructions are issued from time to time. For the latestinformat ion, a lways consul t the current PIONEERService Manual. A subscription to, or additional copiesof, PIONEER Service Manual may be obtained at anominal charge from PIONEER.

(FOR USA MODEL ONLY)1. SAFETY PRECAUTIONS

The following check should be performed for thecont inued protect ion of the customer and serv icetechnician.

LEAKAGE CURRENT CHECKMeasure leakage current to a known earth ground

(water pipe, conduit, etc.) by connecting a leakagecur ren t tes te r such as S impson Mode l 229-2 o requivalent between the earth ground and all exposedmetal parts of the appliance (input/output terminals,screwheads, metal overlays, control shaft, etc.). Plugthe AC line cord of the appliance directly into a 120VAC 60 Hz outlet and turn the AC power switch on. Anycurrent measured must not exceed 0.5 mA.

Deviceundertest

Leakagecurrenttester

Earthground

Reading shouldnot be above0.5 mA

Also test withplug reversed(Using AC adapterplug as required)

LABEL CHECK (for YPWXJ type)

Additional Laser Caution1. Laser Interlock Mechanism

The position of the switch (S8501) for detecting loadingstate is detected by the system microprocessor, andthe design prevents laser diode oscillation when theswitch (S8501) is pressed physically.Thus, the interlock will no longer function if the switch (S8501)is released physically and deliberatery.The interlock also does not function in the test mode ∗.Laser diode oscillation will continue, if pin 62 ofLA9240ML (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 theobjective lens with the naked eye will cause exposureto a Class 1 laser beam.

∗ : Refer to page 62.

•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%).

Electrical AdjustmentCheck the following before starting.(1) Confirm that the tape speed adjustment has been completed.(2) Clean the heads and demagnetize them using a head eraser.(3) Set the measurement level to 0 dBV = 1 Vrms.(4) Use the specified tape for adjustment. Use the labeled (A) side of the test tape.

STD-331E : For playback checkSTD-632 : Normal blank tape

(5) Provide yourself with the following measuring devides:• AC millivoltmeter• Low-frequency oscillator• Attenuator• Oscilloscope

(6) Adjust both right and left channels unless otherwise specified.(7) Turn the DOLBY NR switch off unless otherwize specified.(8) Warm up the unit for several minutes before adjustment. In particular, be sure to warm up the unit in the REC/PLAY mode for 3 to 5 minutes before starting recording/playback frequency characteristics adjustment.(9) Always follow the indicated adjustment order. Otherwise, a complete adjustment may not be achieved.

Playback Adjustment (Decks I and II)(1) Head Azimuth Adjustment(2) Playback Level Adjustment

Recording Adjustment (Deck I)(1) Bias Oscillation Frequency Adjustment(2) Recording Bias Adjustment(3) Recording Level Adjustment.(4) ALC Operation Check

* As the reference recording level is 250nwb/m for STD-331E, the recording level will be higher by 4 dB for STD-331B (160nwb/m). When adjusting, pay carefull attention to the type of tape used.

6.2 CASSETTE DECK SECTION• Adjustment points and test points are shown in Fig.3, Fig.5 and Fig.7.

Mechanical Adjustment• Test tape: NCT-111 (3kHz, 30min).
