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 

Lead in solder used in this product is listed by the California Health and Welfare agency as a known reproductive toxicant which 

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. 

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 60 Hz outlet and turn the AC power switch on. Any 

current measured must not exceed 0.5 mA. 

Device 

under 

test 

Test all exposed 

metal surfaces 

Also test with plug 

reversed 

(Using AC adapter 

plug as required) 

Leakage 

current 

tester 

AC Leakage Test 

Reading should 

not be above 

0.5 mA 

Earth ground 

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 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.

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 1 = 561 ................................................... RD1/4PU 5 6 1 J 

47k Ω = 47 × 10 3 = 473 .................................................. RD1/4PU 4 7 3 J 

0.5 Ω = R50 ...................................................................... RN2H Â 5 0 K 

1 Ω = 1R0 ......................................................................... RS1P 1 Â 0 K 

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

5.62k Ω = 562 × 10 1 = 5621 ........................................... RN1/4PC 5 6 2 1 F

6. ADJUSTMENT 

When the adjustment is made, the product should be connected to a STEREO TUNER AMPLIFIER (SX-R9) . 

For your information, another method (without using the tuner amp.) is explained here. 

6.1 TEST MODE 

7 How to enter the Test Mode 

* In case that the product is connected to an SX-R9 

Select either of the following procedures: 

1. By using the remote control, turn on the power to the 

CT-R5 and receive the " A15F " signal from the 

tuner amp through the bus. 

2. With Power OFF, connect the Pin-15 of the microcomputer 

to GND, and short the TEST MODE 

jumper wires W159(TEST) and W160(GNDD) each 

other on the MCON ASSY. Then turn on the power 

by using the remote control. (Refer to Fig. 6-1.)

7 Test mode operations 

- When the product enters the test mode, two center LEDs will 

flash . 

- All operation buttons, except for the [REC] and [REVERSE 

MODE] Buttons, provide normal operations in the mode. 

- When all LEDs remain extinguished, shift the TC/MD signal 

selector to the MD side inside the CT-R5. 

(1) LED check 

Each time the [REVERSE MODE] button is pushed, the LED 

operation changes as follows: 

Normal display = All LEDs ON = All LEDs OFF = Leaf 

+ SW check 

(2) Leaf SW check 

When the leaf switches are depressed, their corresponding 

LEDs light up as follows: 

Fig . 6 - 1 

* In case that an SX-R9 is not available for adjustment 

- On the CONNECT ASSY, short the pin -7 (GNDD:W128), 

pin -13 (GNDR:W127) and pin-17 (GNDA:W126) of 

CN101 one another. (Refer to A) 

- On the MCON ASSY, short the TEST MODE jumper 

wires W159(TEST) and W160(GNDD) each other. 

(Refer to Fig. 6-1.) 

- Apply the DC power voltage to the Pin-6(+5.6V), Pin-12 

(-7V), and Pin-14(+7V) of respectively. 

(Refer to Fig. 6-2.)

HALF SW ...................................... REV LED 

(3) Auto REC/PLAY operation mode 

Push the [REC] button. The auto REC/PLAY operation mode 

starts: 

1. Sets the function of tuner amp to AUX. 

2. One second later, starts 5-second FWD recording. 

3. Performs REV recording for 5 seconds. 

4. Shifts the function to TAPE, then performs FWD play for 

5 seconds. 

5. Stops operations. 

* When the [REC] button is pushed once again, the above 

operations are repeated. 

** After the auto REC/PLAY operation is completed, when the 

[REV] button is pushed, CT-R5 performs REV play for 5 

seconds and stops operations. 

7 How to cancel the test mode 

To cancel the test mode, push the “POWER” button on the the 

tuner amp to turn off the power to the CT-R5.

6.2 ADJUSTMENT 

7 Adjustment Condition 

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

(Refer to Fig. 6–5). 

(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. 

NCT–111 : For Tape Speed adjustment 

NCT-132X : For Playback adjustment 

STD–632 : 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 kΩ load 

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

ASSY).
