6. ADJUSTMENT
6.1 CD ADJUSTMENT
1)Precautions
• This unit uses a single power supply (+5V) for the
regulator. The signal reference potential, therefore, is
connected to REFO(approx. 2.5V) instead of GND.
If REFO and GND are connected to each other by
mistake during adjustments,not only will it be
impossible to measure the potential correctly,but the
servo will malfunction and a severe shock will be
applied to the pick-up. To avoid this,take special note
of the following.
Do not connect the negative probe of the measuring
equipment to REFO and GND together. It is especially
important not to connect the channel 1 negative
probe of the oscilloscope to REFO with the channel 2
negative probe connected to GND.
Since the frame of the measuring instrument is
usually at the same potential as the negative
probe,change the frame of the measuring instrument
to floating status.
If by accident REFO comes in contact with
GND,immediately switch the regulator or power OFF.
• Always make sure the regulator is OFF when
connecting and disconnecting the various filters and
wiring required for measurements.
• Before proceeding to further adjustments and
measurements after switching regulator ON,let the
player run for about one minute to allow the circuits
to stabilize.
• Since the protective systems in the unit’s software are
rendered inoperative in test mode,be very careful to
avoid mechanical and /or electrical shocks to the
system when making adjustment.
• This unit is adjusted in a combination with the CD
control unit (KEH-M9100ZRN/EW). Each regulator key
should be operated at the unit.
With the KEH-M9100ZRN/EW taken up for reference,
a description will be given below concerning how to
enter into the test mode, including key operations.
The key in the adjustment text is also one of the KEH-
M9100ZRN/EW keys.
• How to enter into the test mode
Switch ACC,back-up ON while pressing the AF and 6
keys together.
• Resetting the test mode
Switch ACC,back-up Off.
• Disc detection during loading and eject operations is
performed by means of a photo transistor in this
unit.Consequently,if the inside of the unit is exposed
to a strong light source when the outer casing is
removed for repairs or adjustment,the following
malfunctions may occur.
*During PLAY, even if the eject button is pressed,the
disc will not be ejected and the unit will remain in
the PLAY mode.
*The unit will not load a disc.
When the unit malfunctions this way,either re-
position the light source,move the unit or cover the
photo transistor.
• When loading and unloading discs during adjustment
procedures,always wait for the disc to be properly
clamped or ejected before pressing another key.
Otherwise, there is a risk of the actuator being
destroyed.
• Turn power off when pressing the button FWD or the
button REV key for focus search in the test mode. (Or
else lens may stick and the actuator may be
damaged.)
• SINGLE/4TRK/10TRK/32TRK will continue to operate
even after the key is released.Tracking is closed the
moment C-MOVE is released.
• JUMP MODE resets to SINGLE as soon as power is
switched off.

•Note :
Unlike previous CD mechanism modules the grating angle of the pickup unit cannot be adjusted after the pickup
unit is changed. The pickup unit in the CD mechanism module is adjusted on the production line to match the CD
mechanism module and is thus the best adjusted pickup unit for the CD mechanism module. Changing the pickup
unit is thus best considered as a last resort. However, if the pickup unit must be changed, the grating should be
checked using the procedure below.
•Purpose :
To check that the grating is within an acceptable range.
•Symptoms of Mal-adjustment :
If the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform
track search operations, or track searching taking a long time, may appear.
•Method :
•Measuring Equipment
•Oscilloscope, Two L.P.F.
•Measuring Points
•E, F, REFOUT
•Disc
•ABEX TCD-784
•Mode
•TEST MODE
•Checking Procedure
1. In test mode, load the disc and switch the 5V regulator on.
2. Using the FWD and REV buttons, move the pickup unit to the innermost track.
3. Press key B to close focus, the display should read "11". Press key A to implement the tracking balance
adjustment the display should now read "5".
4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase
difference is within 75° . Refer to the photographs supplied to determine the phase angle.
5. If the phase difference is determined to be greater than 75° try changing the pickup unit to see if there is any
improvement. If, after trying this a number of times, the grating angle does not become less than 75° then the
mechanism should be judged to be at fault.
•Note
Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be
seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the
average angle.
•Hint
Reloading the disc changes the clamp position and may decrease the "wobble".

•Note :
Unlike the conventional mechanisms, the new mechanism detects the height of the stage using slide-variable
resistance.
To absorb dislocation of the stage height caused by differences in the mechanism and the CD core unit,
adjustment must be made for each CD-mechanism module using a variable resistor.
Normally, readjustment is not needed, as this has been adjusted at the factory. However, adjustment of elevation
is required according to the procedure explained below if an elevation error has occurred or if the CD core unit
has been removed.
•Purpose :
To adjust and confirm whether or not elevation operates correctly.
•Adjustment Method :
•Measuring Equipment:
Millivoltmeter
•Measuring Points :
EREF, EPVO
•Setting :
Without a magazine in Test mode
With the mechanism placed upside-down (Place the CD mechanism module so that the
CD core unit is above.)
•Confirmation Procedure
1.
Enter Test mode, then select Multi-CD player.
2. Press key A to enter Mechanism Test mode.
3.
Press key A twice to specify the amount of movement.

4.
Press key B to set ELV/TRAY mode to TRAY.
5.
Press key FWD to release the clamp and return the tray to
the magazine.
6.
Press key B to enter Elevation Move mode.
7.
Use key FWD/REV to operate elevation and set if to the graduation of the fourth
step (Fig. 1).
8.
Make the adjustment.
Use VR802 to adjust the difference in potential between EREF and EPVO to 0 ±20
mV.
9.
When adjustment is completed, press key BAND/REL to exit
Mechanism Test mode.
10. Confirm operation of the mechanism.
Place the mechanism horizontally (CD core unit below). Take
care not to short-circuit the PCB.
11. Confirm the height of the stage. Use the 6 key to select Disc No.6.
Check if the stopper bend of the clamp lever is engaged in the groove of the frame
stopper (Fig. 2-4).
•Note :
The stopper bend will be pressed downward into the groove for final clamping. Confirm the engagement position
of the stopper bend.
•If the stopper bend is engaged in the center and pressed downward, adjustment is completed. Go to step 15.
•If the stopper bend is dislocated, check the amount of dislocation by following step 12.

12. To see the amount of dislocation, place the mechanism upside-down.
If the stopper bend has been dislocated in the direction of the first
CD, turn VR802 to the left(Fig. 2).
To lower the stage toward the sixth step by 0.1 mm, reduce the
voltage of EREF (adjusted in step 8) by 20 mV.
If the stopper bend has been dislocated in the direction of the sixth
CD, turn VR802 to the right(Fig. 4).
To raise the stage toward the first step by 0.1 mm, increase the
voltage of EREF (adjusted in step 8) by 20 mV.
13. Place the mechanism horizontal. Go back to step 11 to reconfirm the
stage height.
14. When adjustment of the stage height is completed, proceed as
follows:
