nector is plugged or unplugged.

vice pickup unit(see page 31).
4. The doors CAT2248 and CAT2305 have been engaged
each other tightly. When you have to replace the
door CAT2248 or CAT2305, remove both doors from
the Grille to replace them at the same time.

6.1 CD ADJUSTMENT
1)Precautions• This unit uses a single power supply (+5V) for the
regulator. The signal reference potential, therefore, isconnected to REFO(approx. 2.5V) instead of GND.If REFO and GND are connected to each other bymistake during adjustments,not only will it beimpossible to measure the potential correctly,but theservo will malfunction and a severe shock will beapplied to the pick-up. To avoid this,take special noteof the following.Do not connect the negative probe of the measuringequipment to REFO and GND together. It is especiallyimportant not to connect the channel 1 negativeprobe of the oscilloscope to REFO with the channel 2negative probe connected to GND.Since the frame of the measuring instrument isusually at the same potential as the negativeprobe,change the frame of the measuring instrumentto floating status.If by accident REFO comes in contact withGND,immediately switch the regulator or power OFF.
• Always make sure the regulator is OFF whenconnecting and disconnecting the various filters andwiring required for measurements.
• Before proceeding to further adjustments andmeasurements after switching regulator ON,let theplayer run for about one minute to allow the circuitsto stabilize.
• Since the protective systems in the unit’s software arerendered inoperative in test mode,be very careful toavoid mechanical and /or electrical shocks to thesystem when making adjustment.
• This unit is adjusted in a combination with the CDcontrol unit (KEH-M9116ZT/ES, etc.). Each regulatorkey should be operated at the unit. With the KEH-M9116ZT/ES taken up for reference, adescription will be given below concerning how toenter into the test mode, including key operations.The key in the adjustment text is also one of the KEH-M9116ZT/ES keys.
• How to enter into the test modeSee the test mode flow chart Page 29.
• Resetting the test modeReset to the unit.
• Disc detection during loading and eject operations isperformed by means of a photo transistor in thisunit.Consequently,if the inside of the unit is exposedto a strong light source when the outer casing isremoved for repairs or adjustment,the followingmalfunctions may occur.*During PLAY, even if the eject button is pressed,the
disc will not be ejected and the unit will remain inthe 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 thephoto transistor.
• When loading and unloading discs during adjustmentprocedures,always wait for the disc to be properlyclamped or ejected before pressing another key.Otherwise, there is a risk of the actuator beingdestroyed.
• Turn power off when pressing the button FF or thebutton REV key for focus search in the test mode. (Orelse lens may stick and the actuator may bedamaged.)
• SINGLE/4TRK/10TRK/32TRK will continue to operateeven after the key is released.Tracking is closed themoment C-MOVE is released.
• JUMP MODE resets to SINGLE as soon as power isswitched off.

•Note :Unlike previous CD mechanism modules the grating angle of the pickup unit cannot be adjusted after the pickupunit is changed. The pickup unit in the CD mechanism module is adjusted on the production line to match the CDmechanism module and is thus the best adjusted pickup unit for the CD mechanism module. Changing the pickupunit is thus best considered as a last resort. However, if the pickup unit must be changed, the grating should bechecked 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 performtrack 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 Procedure1. In test mode, load the disc and switch the 5V regulator on.2. Using the TRACKUP and TRACKDOWN buttons, move the pickup unit to the innermost track.3. Press key RPT(ch5) to close focus, the display should read "91". Press key DISCDOWN to implement the tracking
balance adjustment the display should now read "81". Press key RPT(ch5) 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 phasedifference 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 anyimprovement. If, after trying this a number of times, the grating angle does not become less than 75° then themechanism should be judged to be at fault.
•NoteBecause of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may beseen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates theaverage angle.
•HintReloading 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-variableresistance.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 elevationis required according to the procedure explained below if an elevation error has occurred or if the CD core unithas 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 theCD core unit is above.)
•Confirmation Procedure
1. Enter Test mode, then select Multi-CD player.
2. Press key RDM(ch6) to enter Mechanism Test mode.
3. Press key ch1 twice to specify the amount of movement.

4. Press key RPT(ch5) to set ELV/TRAY mode to TRAY.
5. Press key TRACKUP to release the clamp and return the tray to the magazine.
6. Press key RPT(ch5) to enter Elevation Move mode.
7. Use key TRACKUP/DOWN to operate elevation and set if to the graduation of thefourth step (Fig. 1).
8. Make the adjustment. Use VR802 to adjust the difference in potential between EREF and EPVO to 0 ±20mV.
9. When adjustment is completed, press key SCAN(ch4) to exit Mechanism Testmode.
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 DISCUP key to select Disc No.4.
Check if the stopper bend of the clamp lever is engaged in the groove of the framestopper (Fig. 2-4).
•Note :The stopper bend will be pressed downward into the groove for final clamping. Confirm the engagement positionof 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 firstCD, turn VR802 to the left(Fig. 2).
To lower the stage toward the sixth step by 0.1 mm, reduce thevoltage of EREF (adjusted in step 8) by 20 mV.
If the stopper bend has been dislocated in the direction of the sixthCD, turn VR802 to the right(Fig. 4).
To raise the stage toward the first step by 0.1 mm, increase thevoltage of EREF (adjusted in step 8) by 20 mV.
13. Place the mechanism horizontal. Go back to step 11 to reconfirm thestage height.
14. When adjustment of the stage height is completed, proceed asfollows:
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 theadjustment again.
