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 (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.
(FOR USA MODEL ONLY)
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 60Hz outlet and turn the AC power switch
on. Any current measured must not exceed 0.5mA.
Reading should
not be above
0.5mA
Earth

Also test with

Test all
exposed metal
surfaces
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
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.

THIS PIONEER APPARATUS CONTAINS
LASER OF CLASS ΙΙΙ b.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUTED PERSON.
1. Laser Interlock Mechanism
The position of the switch (S601) for detecting loading
state is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch
(S601) is not on CLMP terminal side (CLMP signal is OFF
or high level.). Thus, the interlock will no longer function if
the switch (S601) is deliberately set to CLMP terminal side
(low level).
The interlock also does not function in the test mode ∗.
Laser diode oscillation will continue, if pin 1 of M51593FP
(IC101) on the PRE-AMP BOARD ASSY mounted on the
pickup assembly is connected to GND, or pin 19 is
connected to low level (ON), or else the terminals of Q101
are shorted to each other (fault condition).
2. When the cover is opened with the servo mechanism
block removed and turned over, close viewing of the
objective lens with the naked eye will cause exposure to a
Class 1 laser beam.

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

7.3.2 Laser Hour Meter display and Error code display for service.
CDR-850 can be displayed the total of the lighting time of Laser diode and the error code for service.
When this product keeps pushing the STOP key in the TEST mode (potitioin of INPUT selector AES/EBU in ST0P) for about five seconds, the
following displays are done by FL display.
******
Laser Hour Meter displayError code Number
Four digit in the left of FL : Total lighting time of laser diode.
Two digit in the right of FL : Error code for service.
0-5100 hours are displayed at the total lighting time of laser diode.
As for the error code for service, Error Number displayed as "CHECK DISC" or "CHECK" is displayed.
Refer to the attached table to the content.
As for the initialization of the total lighting time of laser diode, when you keeps pushing the MENU key and the SKIP SET key at the same time
for five seconds when this product is STOP at the AES/EBU position of the INPUT selector in the TEST mode is initialized.
"CLEAR" is displayed in FL display, and the total time is cleared.
Initialization of error code display.
When the power is turned on again, the error code is automatically cleared.
In CDR-850, when "SKIP PLAY" key and "MENU" key are pushed
at the same time on the ordinary mode, the error code of details is
displayed in FL display. As for the error code of details, the packing
improvement is not done. When the power supply is turned off, the
error code of details is deleted.
The display of eight digits is as follows.
