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 safety 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 safety, 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)

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.

    A["Device under test"] --> B["Test all exposed metal surfaces"]
    B --> C["Leakage current tester"]
    C --> D["Reading should not be above 0.5mA"]
    E["Also test with plug reversed (Using AC adapter plug as required)"] --> B
    F["Earth ground"] --> C

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 dose 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.

2. EXPLODED VIEWS AND PARTS LIST

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.

- Screws adjacent to ▼ mark on the product are used for disassembly.

5. PCB PARTS LIST

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 [R] [5] [0] K
1 Ω	→	1R0	......		RS1P [1] [R] [0] K

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

5.62kΩ → 562×10 ^1 → 5621....RN1/4PC5621F

6. ADJUSTMENT

- Adjustment points and Measurement points are shown in Fig. 6-6.

6.1 MECHANICAL ADJUSTMENT

6.1.1 Door Damping Check and Adjustment (except CT-W706DR)

Set the door spring of the DECK I side to position (A) as shown in Fig. 6-1. Then, erect the front panel assembly vertically.

Open the doors of DECK I and DECK II at the same time. At this point, confirm that the difference between the door completely opened and the other door is within 15 mm. If this standard is not satisfied install the door spring of DECK I at another position and adjust as follows:

• When the door of DECK I opens later than that of DECK II: Change the door spring of DECK II from (A) to (B).
• When the door of DECK I opens faster than that of DECK II: Change the door spring of DECK I from (A) to (B).

Fig. 6-1

6.1.2 Tape Speed Adjustment

● Perform this adjustment in the test mode.

● Test Mode Setting

(1) Press the TIME/COUNT and RESET keys of DECK I together with the PAUSE key of DECK II.

(2) The speed becomes normal when the PLAY key is pressed, and double when the FF key is pressed.

(3) To cancel the TEST mode, press the RESET key of DECK I or turn off the power.

(2) Recording Bias and Recording Level Automatic Adjustment REC Adjustment Check

1. Test tape DECK II STD-632 set in.
2. Test mode setting.

① Press the test mode, set both TIME/COUNT and RESET keys of DECK I together with the PAUSE key of DECK II all together.
② Set COPY START key is press push.
③ When the REC key (DECK II) is pressed, "B" flashes on the counter, and adjustment of bias and recording level is started automatically.

- When correct adjustment has been completed, the mechanism stops for about 50 seconds, and "PBR" lights on the DECK II side counter to indicate that all adjustments have been completed.

- At this time, flashing of "B" indicates a bias adjustment error, while flashing of "R" indicates a recording level error.

④ With correct adjustment, “PBR” lights on the DECK II side of the counter. When the DECK II side counter does not light, no adjustment value is written into the memory.
⑤ When the STOP key is pressed, the automatic adjustment mode is cancelled. At this time, the counter display becomes "10" on the DECK I side and "TUNE" on the DECK II side. (See Fig. 6-5)

Fig. 6-5 FL Display Example
⑥ Press the RESET Key at the DECK I, canceling the test mode.
Adjustment NG : The following are possible reasons.

● No recording
● No adjustment tape. Near the tape end.
● Tape is extremely damaged.
● Circuit trouble (defective contact etc.)
Note: For repeat adjustment, press the STOP key (DECK Ⅱ) to leave automatic adjustment mode, and then start again.
