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 units 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 KEHM9100ZRN/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 reposition 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.

6.2 CHECKING THE GRATING

- Checking the Grating After Changing the Pickup Unit
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 Measuring Points Disc Mode

L.P.F.

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".

6.3 ADJUSTMENT OF ELEVATION WHEN THE CD CORE UNIT HAS BEEN REMOVED FOR MAINTENANCE
- Adjustment When Error Code 60 is Displayed Because of Malfunctioning Elevation
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.)

mV meter EPVO EREF

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. The amount of movement changes each time key A is pressed. maximum movement Key A during movement Key A Key A minimum movement
Examples of display 4. Press key B to set ELV/TRAY mode to TRAY. key B TRY mode ELV mode
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 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: 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.
