6. ADJUSTMENT
6.1 CD ADJUSTMENT
- 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.

6.2 CHECKING THE GRATING
- Checking the Grating After Changing the Pickup Unit
· 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 · Measuring Points · Disc · Mode

· Oscilloscope, Two L.P.F. · E, F, REFO · ABEX TCD-784 · 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".

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 : 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.)

- 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).
