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 (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. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTENTIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURN- ING 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.

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 Leakage current tester Earth ground Reading should not be above 0.5 mA Also test with plug reversed (Using AC adapter plug as required) Test all exposed metal surfaces AC Leakage Test www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com MJ-D508 3 IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON. LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 27.4 mW WAVELENGTH: 785 nm Control method of the current through a laser diode. The resistor R105 on the CORD MAIN UNIT ASSY (For MD mechanism assembly) are for the limiting of current through a laser diode. Control method of the laser output power The laser pick-up assembly provide the photo-diodes and APC (Auto Power Control) circuit. The photo-diode detect output of the laser diode then IC104 control the APC circuit according to the signal voltage of the photo-diode via IC101. The Variable resistancer on the FPC in the Laser pick-up assembly can be adjusted the output level of Laser diode to fix the rated output level. Laser Interlock Switch The loading position detect switch S101 is set to “ LOAD ON ” (ON: low level, OFF: high level) position, IC104 get the “ LOAD ” signal, and hand the laser “ LDON ” signal to No. 9 terminal (LDON) of the Laser pick-up assembly. Then a laser diode can be lighted exept when the level of signal “LOAD ” is low.

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  5 0 K 1 Ω = 1R0 ......................................................................... RS1P 1  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 ...........................................

By software selection, it functions as the input terminals for the timers B0 to B2, the output terminals for the D/A converter, the expansion input terminals of the A/D converter, or the A/D trigger input terminals. This is the terminal for switching the external data bus width. When the level of this terminal is "L", the width is 16 bits, and when it is "H", the width is 8 bits. Please fix it to one of these levels. At the time of single-chip mode, connect it to the Vss terminal. This is the terminal for processor mode switching. At the time of single-chip mode or at the time of memory expansion mode, connect it to the Vss terminal. At the time of microprocessor mode, connect it to the Vcc terminal. P80 to P84, P86, and P87 are I/O ports with the same functions as P0. By software selection, they function as the I/O terminals for the timer A4 or the input terminals for external interrupt. P86 and P87 function by software selection as the I/O terminals for the subclock oscillation circuit. In this case, connect a crystal oscillator between P86 (XCOUT terminal) and P87 (XCIN terminal). P85 is an input-only port serving also as NMI. When the input of this terminal changes from "H" to "L", and NMI interrupt is generated. The NMI function can not be cancelled by software. A pullup resistance can not be set for this terminal. When the input to this terminal is "L", the microcomputer is reset. This are the I/O terminals of the main clock oscillation circuit. Connect a ceramic oscillator or a crystal oscillator between the terminals XIN and XOUT. In case of an externally generated clock, enter the clock from the XIN terminal and leave the XOUT terminal open. Impress 0 V. Impress 2.7 V to 5.5 V. These are 8 bit I/O ports with the same functions as P0. By software selection, they function as the I/O terminals for the timers A0 to A3. These are 8 bit I/O ports with the same functions as P0. By software selection, they function as the I/O terminals for the UART0 and UART1. These are 8 bit I/O ports with the same functions as P0. By software selection, they put out a clock with 1/8 or 1/32 of XIN or with the same cycle as XCIN from P57. WRL, WRH, (WR, BHE), RD, BCLK, HLDA, and ALE signals are put out. Switching between WRL and WRH and between BHE and WR is possible by software. At the time of WRL, WRH, RD selection When the external data bus width is 16 bits and the WRL signal is at "L" level, writing is done to an even address, and the WRH signal is at "L" level, writing is done to an odd address. Reading is performed when the RD signal is at "L" level. At the time of WR, BHE, RD selection Writing is done when the WR signal is at "L" level. Reading is done when the RD signal is at "L" level. An odd address is accessed when the BHE signal is at "L" level. Please use this mode when the external data bus width is 8 bits. The microcomputer is in hold status while the input level to the HOLD terminal is "L". During hold status, the output from HLDA is at "L" level. ALE is the signal for address latching. The microcomputer is in ready status while the input to RDY is at "L" level. A clock with the same frequency as the internal clock ø is put out from the BCLK terminal. These are 8 bit I/O ports with the same functions as P0. The A16 to A19 and CS0 to CS3 signals are put out. A16 to A19 are the upper 4 bits of the address. CS0 to CS3 are the chip select signals, and they are used for specification of the access space.
