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 connect-

ing and disconnecting the various filters and wiring
required for measurements.

• Before proceeding to further adjustments and mea-

surements 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-P7000, etc.). Each regulator key
should be operated at the unit.
With the KEH-P7000 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-P7000
keys.

• How to enter into the test mode

Switch ACC,back-up ON while pressing the 4 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 FF 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.

CDX-M2086ZBM

•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 FF and REV buttons, move the pickup unit to the innermost track.

3. Press key 9 to close focus, the display should read "91". Press key 8 to implement the tracking balance adjust­ment the display should now read "81". Press key 9 4 times. The display will change, returning to "81" on the
fourth press.

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 Equlpment: 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 7 to enter Mechanism Test mode.

3. Press key 12 twice to specify the amount of movement.

6. Press key 9 to enter Elevation Move mode.

7. Use key FF/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 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 4 key to select Disc No.4.

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 steps 12 to 14.

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:

15. Press the EJECT switch.

16. Once operation of the mechanism has stopped, turn the power OFF.

17. Wait more than one minute after the power is turned off, then turn the power ON and insert a magazine.

18. Check if the mechanism operates correctly with the first and fourth CDs.

19. If the mechanism operates properly, adjustment is completed. If the mechanism operates improperly, make the
adjustment again.

- New Test Mode(aging operation and setup analysis)

The single CD player plays in normal mode. After being set up, it will display FOK (focus), LOCK (spindle), subcode,
sound skip, protection against a mechanical error or the like, occurrence of an error, cause and time of an expiry, if
any, (and disc number)
During the setup, the CD software operation status (internal RAM and C-point)is displayed.
