3. SERVICING HINTS
In order to prevent loose metal objects from getting in
the CD mechanism it will be necessary to see to a
clear repair station.
Before the player is being used or serviced, the
transportation screws should be removed.
These screws have to be reapplied after servicing.
The objective can be cleaned with a blow brush.
For servicing hints for the CD mechanism refer to
Service Manual CDM-0 and CDN-1.
Do not loosen any screws other than those mentioned
in the hints.
All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are connected
with the same potential as the mass of the set via a
wrist wrap with resistance.
Keep components and tools also at this potential.

The servo uP can beset to the servicing mode to check the
switch and display PCB and to separately test the servo
systems.
INITIATING SERVICE LOOP A
-—— Put a disc on the turntable.
— Simultaneously depress the CANCEL, PREVIOUS
and STOP keys.
Keep these three keys depressed while switching on
the mains voltage. In this situation the laser and focus
contro! are operative and the turntable motor is
running.
The light pen remains situated under the lead-in
tracks. The radial servo system is switched off.
In this service loop the display can be checked as
follows:
— The display will indicate 01.02, then 02.04, 03.06 and
continue in this way up to 20.40. 20.40 is followed
again by 00.00, 01.02, etc.
The indicators SCAN, PAUSE, REPEAT and DISC
ERROR will light up and will remain switched on.
At indication 01.02, bar 1 of the track bar is also driven
and at 02.04 bar 2, etc.
— If now the CANCEL key is depressed, the TRACK
indication will light up after 2 clock strokes of the
display and the DISC ERROR indication will go off.
The player stays in service loop A.
INITIATING SERVICE LOOP B
The player can be brought from service loop A into service
loop B by depressing the STORE key. Now the radial
servo system has been switched on independently of the
P-bit and the sub-code.
The display makes clear that the set is in service loop B by
means of ABS, REL and TOT.
The player can be brought from service loop B in the
PLAY mode by depressing the START/REPLAY key.
For adjustments that have to be performed on the lower
side for which the unit should be in the position of normal
end use, servicing supports are supplied.
Code number is 4822 395 30202.
These supports can be mounted in the four holes of the
frame.
DEMOUNTING THE TOP COVER
— Remove the 4 screws in the sides.
— Remove the cover from the set by pulling it backwards.
Attention
When mounting the top cover; care should be taken that
the top cover is placed correctly in the guidings of the
front before mounting the four screws.

the front of the set can be removed.
Demounting the control and display PCB
— Remove the 9 screws on the control and display PCB.
— The PCB can now be taken away with the headphone
PCB still in place.
Demounting the headphone PCB
Once the control and display PCB has been taken away,
the headphone PCB can be removed.

SERVICING THE SUPPLY PCB
— Remove the 2 screws B (see Fig. 3a).
— When the connectors have been loosened, the supply
PCB can be taken out of the set from the rear.
Attention
The Audio cable is soldered to the decoder PCB.
When mounting the supply PCB care should be taken that
the PCB falls in the guiding on the frame.
SERVICING THE SERVO PCB AND THE DECODER PCB
(see Fig. 3a)
— Remove the top cover.
— Remove the 2 screws A on the PCB holder.
— When the PCB holder is placed in the service position
(see Fig. 4) measurement can be performed on both
the servo PCB and the decoder PCB.
SERVICING THE IR RECEIVER
For practical reasons, it is best to service the IR receiver
by means of the trial and error method, with which
defects, if any, are traced.
Code number of IR receiver: 4822 212 21449.
After removing the bottom plate, this receiver can be con-
nected via plug 91.
Demounting the IR receiver:
— Remove the top cover.
— Remove the loading mechanism
— When clamping spring 555 has been removed, the
receiver can be demounted.

MENTS
MECHANICAL MEASUREMENTS AND ADJUSTMENTS
TO BE PERFORMED ON THE CDM
— Height setting of the turntable
In case of adjustment of the height of the turntable by
means of the set screw on the motor shaft, the voltage
across resistor 3240 on the servo PCB should be set to
0 Volt.
- Checking and adjusting the angle setting
For checking and adjusting the angle setting see the
Service Manual! of C.D.M.
Note
For checking and adjusting the angle setting the drawer
mechanism has to be demounted.
See sub servicing hints.
MECHANICAL ADJUSTMENTS OF THE TRAY
MECHANISM
Adjusting the clearance of the disc (see Fig. 5)
FT-HAND F THE LOADING MECHANISM
Fig. 5 36013A22
The disc may not rub against the black lifting plate (item
513 of the Exploded View Tray).
In case this should happen, the clearance can be adjusted
with adjusting plate G and screw H.
With those the height of axis J of the lifting plate can be
adjusted.
The adjustment should be performed with the drawer in
position ‘CLOSE’.
When screw H is loosened, adjusting plate G can be dis-
placed in so far as this is allowed by the slotted hole of
adjusting plate G.
If you can hear the disc rubbing, the adjusting plate
should be adjusted.
In practice the disc will be adjusted parallel to edge | of the
tray chassis.
