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 differ- ence 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 aver- age angle. • Hint Change the disc changes the clamp position and may decrease the "wobble". REFO E F E F L.P.F. L.P.F.

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. 6.2 ADJUSTMENT OF ELEVATION WHEN THE CD CORE UNIT HAS BEEN REMOVED FOR MAINTENANCE - Adjustment When Error Code 60 is Displayed Because of Malfunctioning Elevation TRACK FUNCTION ' " TRACK FUNCTION 72 00' 00" EREF EPVO Oscilloscope CD CORE UNIT L.P.F. 47kΩ 1µF Examples of display TRACK FUNCTION 72 00' 02" TRACK FUNCTION 72 00' 01" The amount of movement changes each time key 12 is pressed. maximum movement i Key 12 i during movement i Key 12 i minimum movement TRACK FUNCTION 72 00' 00" i i Key 12 www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 32 CDX-P656,P25 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-cir- cuit 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.

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 volt- age 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 volt- age 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 fol- lows: 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.

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 mis- take during adjustments, not only will it be impossi- ble 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 fol- lowing. 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 usual- ly at the same potential as the negative probe, change the frame of the measuring instrument to floating sta- tus. 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 stabi- lize. • 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 sys- tem when making adjustment. • Disc detection during tray extraction and return oper- ations 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 mal- functions 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-posi- tion 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” sta- tus 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 auto- matic adjustment value to the initial value. • During exchanging discs, do not press the keys for the discs to be exchanged. 7.2.2 TEST MODE - CD Test Mode Key to adjustment text HEAD UNIT (6 keys type) inside (12 keys type) BAND BAND TRK+/FF TRK+/FF TRK-/REV TRK-/REV 7 1 8 2 9 3 10 4 11 5 12 6 DISC- DISC- SOURCE ON/OFF SOURCE ON/OFF www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 43 CDX-P656,P25 Focus Close *2 S Curve Check 01 01 01 00 00 00 (99 99 99) Display TYP 4 9 Reset SOURCE New test mode 6 TRK- BAND 9 *2 *1 +6dB +12dB *4 *5 12 12 12 12 7 8 7 8 TRK+ TRK+ TRK- 06 06 06 12 12 12 Sourse CD Single TR 9x(8x):91(81) 32TRK 92(82) CRG Move 94(84) 100TRK 93(83) Focus Mode Select Focus Close/ S Curve Check CRG− Auto Adjustment Display Select CRG+ RF AGC Coefficient Display/ Rough Servo and RF AGC Tracking Open Display Tracking Open T.

(1) Basic Indication Method 1) When SERRORM is selected for the CSMOD (CD mode area for the system), error codes are written to DMIN (min- utes 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.

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).
