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

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

THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUTED PERSON.
The output power at the objective lens of this assembly is 0.73 mW.
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.

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. 1When 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
47k Ω = 47 × 10
0.5 Ω = R50 ...................................................................... RN2H Â50 K
1 Ω = 1R0 ......................................................................... RS1P 1Â0 K
Ex. 2When there are 3 effective digits (such as in high precision metal film resistors).
5.62k Ω = 562 × 10

These are 8 bit I/O ports with the same functions as P0. 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.

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

MAINTENANCE OF EXTERNAL SURFACES
÷ Use a polishing cloth or dry cloth to wipe off dust and
dirt.
÷ When the surfaces are very dirty, wipe with a soft cloth
dipped in some neutral cleanser diluted five or six times
with water, and wrung out well, and then wipe again
with a dry cloth. Do not use furniture wax or cleaners.
÷ Never use thinners, benzine, insecticide sprays and
other chemicals on or near this unit, since these will
corrode the surfaces.
