1. SAFETY INFORMATION
This service manual is intended for qualified service technicians ; it is not meant for the casual do-ityourselfer. 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 This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to 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 be of identical designation.

1. SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
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.
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.
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.
Device under test Test all exposed metal surfaces
Reading should Leakage not be above current 0.5mA tester
Also test with plug reversed (Using AC adapter plug as required)

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.

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%). 561 ........................................................

Adjustment points and Measurement points are shown in Fig. 6-5.
6.1 MECHANICAL ADJUSTMENT
6.1.1 Door Damping Check and Adjustment 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).

6.1.2 Tape Speed Adjustment
¶
Perform this adjustment in the test mode. ÷ Test Mode Setting (1) Press the STOP keys of DECK I together with the PAUSE key and the REC MUTE 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 STOP key of DECK I together with the STOP key of DECK II or turn off the power.

6.2 ELECTRICAL ADJUSTMENT
Adjustment Conditions (1) The mechanical adjustments must be completed first. (2) The head must be cleaned and demagnetized. (3) Turn the power on allow the deck to warm up for at least a few minutes before commencing any electrical adjustments. (4) The reference signal is 0 dBV = 1 Vrms. (5) Connect a 10 k load resistance to the OUTPUT terminals. (6) Unless otherwise specified, the switches listed below are left in the positions indicated.
