1. SAFETY INFORMATION

1. SAFETY PRECAUTIONS The following check should be performed for thecontinued protection of the customer and serv icetechnician.

ANY MEASUREMENTS NOT WITHIN THE LIMITS

OUTLINED ABOVE ARE INDICATIVE OF A PO-

TENTIAL SHOCK HAZARD AND MUST BE COR-

RECTED BEFORE RETURNING THE APPLIANCE

TO THE CUSTOMER.

2. PRODUCT SAFETY NOTICEMany electrical and mechanical parts in the appli-

ance have special safety related characteristics. Theseare oft en not evident from visual inspection nor theprotection afforded by them necessarily can be ob-tained by using replacement components rated forvoltage, wattage , etc. Replacement parts which havethese special safety characteristics are identified inthis Service Manual.

Electrical 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 which

does not have the same safety characteristics as thePIONEER recommended replacement one, shown inthe parts list in this Service Manual, may create shock,fire, or other hazards.

Product Safety is continuously under review andnew instructions are issued from time to time. Forthe latest information, always consult the currentPIONEER Service Manual. A subscription to, or ad-ditional copies of, PIONEER Service Manual may beobtained at a nominal charge from PIONEER.

LEAKAGE CURRENT CHECK

Measure leakage current to a known earth ground(water pipe, conduit, etc.) by connecting a leakagecurrent tes ter such as Simpson Model 229-2 orequivalent 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.

(FOR USA MODEL ONLY)

Also test with plugreversed(Using AC adapterplug as required)

Deviceundertest

Test all exposedmetal surfaces

Earth ground

Leakagecurrenttester

Reading shouldnot be above0.5 mA

AC Leakage Test

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

Lead in solder used in this product is l isted by the California Health and Welfare agency as a known reproductive toxicant whic h

may cause birth defects or other reproductive harm (California Health & Safety Code, Section 25249.5).

When servicing or handling circuit boards and other components which contain lead in solder, avoid unprotected skin contact with

the solder. Also, when soldering do not inhale any smoke or fumes produced.

REMARQUE

(POUR MODLE CANADIEN SEULEMENT)

Les symboles de fusible (fusible de type rapide) et/ou (fusible de type lent) sur CCI indiquent que les

pices de remplacement doivent avoir la mme dsignation.

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.

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= 56 10 1= 561................................................... RD1/4PU561 J

0.5= R50 ...................................................................... RN2H50 K

1= 1R0 ......................................................................... RS1P10K

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

6.2 ADJUSTMENT

7 Adjustment Condition(1) The ground at the time of adjustment shall be W153.

(Refer to Fig. 65).

(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.

NCT111 : For Tape Speed adjustment

NCT-132X : For Playback adjustment

STD632 : Normal blank tape

* As the reference recording level is 250 nwb/m for NCT

132X, 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.

(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.

Note: In case of adjustment as a single unit, connect a 22 k load

resistor to pins 16(PBR) and 18 (PBL)of CN101(CONNECT

ASSY).
