Qualified technicians have the necessary test equipment and tools, and have beentrained 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 mayvoid the warranty. If you are not qualified to perform the repair of this product properly and safely, youshould not risk trying to do so and refer the repair to a qualified service technician.
WARNINGThis product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to causecancer, birth defects or other reproductive harm.
Health & Safety Code Section 25249.6 – Proposition 65
1. SAFETY PRECAUTIONS The following check should be performed for thecont inued protect ion of the customer and servicetechnician.
ANY MEASUREMENTS NOT WITHIN THE LIMITSOUTLINED ABOVE ARE INDICATIVE OF A PO-TENTIAL SHOCK HAZARD AND MUST BE COR-RECTED BEFORE RETURNING THE APPLIANCETO THE CUSTOMER.
2. PRODUCT SAFETY NOTICE Many electrical and mechanical parts in the appli-ance have special safety related characteristics. Theseare often 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 whichdoes 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 leakagecur ren t tes ter such as S impson Mode l 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
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.
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.

5. PCB PARTS LISTNOTES : ÷ 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 J47k Ω = 47 × 10 3 = 473 ..................................................RD1/4PU 4 7 3 J0.5 Ω = R50 ......................................................................RN2H Â 5 0 K1 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

7.1.2 TEST MODE
1. Entry into Test ModeSwitch on the power while pressing 1/4 and 1/1 of the beat switch. (Refer to Fig 1)¶ With correct entry into test mode, "F ." is displayed on the BPM display.¶ When the beat switch is released, the unit automatically enters into mode 1 and the BPM display becomes "F_1".
2. Explanation of each Mode and Setting Method2.1 Explanation of each mode Mode 1 ... The LED self-illuminating button, the LED coupled to the lever switch, and the effect time display coupled to the time
button are checked. Mode 2 ... MIDI LED and BPM mode switch are checked. Mode 3 ... The LEDs other than mode 1 are checked.
2.2 Setting method Mode switching is done with the BPM mode switch. Each time the switch is pressed, switching is done in the order of mode 1= mode 2 = mode 3 = mode 1 ... From any mode, mode 3 is reached by pressing the tap button. The LED (1/1) of the beat switch lights when the mode shifts from mode 3 to mode 1.
3. Check Methods in each Mode and their Points
3.1 Mode 1 Mode 1 is reached by the following operations A and B.A. When test mode is entered and the beat switch (1/4 and 1/1) is released.B. When the BPM mode switch is pressed once in mode 3. At this time, "3210" is displayed a the effect time display position, and "F_1" is displayed at the BPM display position.¶ The "F_1" display permits confirmation that the 7 segments are not short-circuited.
3.1.1 Check method Of the following switches, only the effect selection button flashes when the switch is pressed. All other switches light when the switch is pressed and go out when the switch is pressed again.
3.1.2 Check points Effect selection button Frequency selection button Beat effect ON switch Beat switch (1/4 ~ 4/4) Effect time button and effect time display (* All four digits of the display count up at the same time.) Hold button Play button Jog effect ON switch
3.2 Mode 2 Mode 2 is entered when the BPM switch is pressed in mode 1. At this time, the effect time display goes out and "F_2" is displayed on the BPM display.
3.2.1 Check contents Mode switching with the BPM mode switching switch. (The MIDI LED lights.) Note: Some of the LEDs lit in mode 1 may not go out, but this is not a defect.

3.3 Mode 3 Mode 3 is reached by the following operations A and B.A. When the BPM switch is pressed in mode 2. At this time, "0000" is displayed on the time display, and "000" is displayed on the BPM display.B. When the tap switch is pressed in mode 1 or mode 2. At this time, "1111" is displayed on the time display, and "111" is displayed on the BPM display.
3.3.1 Check method When the tap switch is hit, the following indications change.
Checked indication DescriptionInput level meter Lights one by one from the bottom.Effect out level meter Lights one by one from the bottom.Effect time display Number display is performed with all four digits counting up simultaneously.BPM display Number display is performed with all three digits counting up simultaneously.Beat LED Lights one by one from the left.Jog meter Lights one by one from the left.
