• Note :

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, REFO

• Disc • ABEX TCD-784

• Mode • TEST MODE

• Checking Procedure

1. Enter Test mode, then select Multi-CD player and switch the 5V regulator on.

2. Using the TRK+ and TRK- buttons, move the pickup unit to the innermost track.

3. Press key 9 to close focus, the display should read "91". Press key 9 2 times. Enter Rough Servo mode. Press key
8 to implement the tracking balance adjustment the display should now read "81".

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

Change the disc changes the clamp position and may decrease the "wobble".

• Note :

This mechanisms is 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: Oscilloscope, One L.P.F.

• 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.

4. Press key 9 to set ELV/TRAY mode to TRAY.

5. Press key FF to release the clamp and return the tray to the magazine.

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 third step

(Fig. 1).

8. Make the adjustment.
Use VR802 to adjust the difference in potential between EREF and EPVO to 0 ±10
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 DISC± key to select Disc No.3.

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.

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.

• Disc detection during tray extraction and return oper­ations is performed by means of the photo transistor
in this unit. Consequently, if the inside of the unit is
exposed to a strong light source with the outer casing
removed for repairs or adjustment, the following mal­functions may occur:

*Even with a disc loaded, the unit detects "no disc"

and cannot start play.

*Although a 12-cm disc is loaded, the unit detects

"8cm disc" mistakenly.
When the unit malfunctions this way, either re-posi­tion the light source, move the unit or cover the photo
transistor.

• During exchanging discs, do not press the keys for
the discs to be exchanged.

2) Test Mode
This mode is used for adjusting the CD mechanism
module of the device.

• Test mode starting procedure

Reset while pressing the 4 and 6 keys together.

• Test mode cancellation
Switch ACC, back-up OFF.

• If the 8 or 9 key is pressed while focus search is in
progress, immediately turn the power off (otherwise
the actuator may be damaged due to the lens stuck).

• Jump operation of TRs other than 100TR continues
after releasing the key. CRG move and 100TR jump
operations are brought into the “Tracking close” sta­tus when the key is released.

• Powering Off/On resets the jump mode to “Single TR
(91)”, the RF AMP gain setting to 0 dB, and the auto­matic adjustment value to the initial value.

• During exchanging discs, do not press the keys for
the discs to be exchanged.

- Error Messages

If a CD is not operative or stopped during operation due to an error, the error mode is turned on and cause(s) of the
error is indicated with a corresponding number. This arrangement is intended at reducing nonsense calls from the
users and also for facilitating trouble analysis and repair work in servicing.

(1) Basic Indication Method

1) When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN (min­utes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO remains
in blank as before.

2) Head unit display examples
Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.

8-digit display 6-digit display 4-digit display

ERROR–xx ERR–xx E–xx

OR

Err–xx

* When the system is manufactured for an OEM basis, the error display will be configured according to the customer

specification.

Remarks: Unreadable TOC does not constitute an error. An intended operation continues in this case.

A newly designed head unit must conform to the example given above.
Upper digits of an error code are subdivided as shown below:
1x: Setup relevant errors, 3x: Search relevant errors, 3x: Search relevant errors, Ax: Other errors.

- New Test Mode

M-CD plays the same way as before.
If an error such as off focus, spindle unlocking, unreadable sub-code, or sound skipping occurs after setup, its
cause and time occurred (in absolute time) are displayed.
During setup, operational status of the control software (internal RAM: CPOINT) is displayed.
These displays and functions are prepared for enhancing aging in the servicing and efficiency of trouble analysis.

(1) Shifting to the New Test Mode

1 Turn on the current test mode by starting the reset from the 4 and 6 keys together.
2 Select M-CD for the source through the specified procedure including use of the [SOURCE] key. Then, press the

12 key while maintaining the regulator turned off.

3 After the above operations, the new test mode remains on irrespective of whether the M-CD is turned on or off.

You can reset the new test mode by turning on the reset start.

* With some products, the new test mode can be reset through the same operations as that employed for shifting to

the STBY mode (while maintaining the Acc turned off).
