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.
Reading should not be above
0.5 mA
Earth ground
Device under test
Also test with plug reversed (Using AC adapter plug as required)
Leakage
current
tester
Test all exposed metal surfaces
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 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.

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 micro­ computer 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:
+5.6V
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.)

(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.
