Symbol indicates a resistor.No differentiation is made between chip resistors anddiscrete resistors.

NOTE :

Symbol indicates a capacitor.No differentiation is made between chip capacitors anddiscrete capacitors.

A TUNER AMP UNIT

For resistors and capacitors in the circuit diagrams, their resistance values or capacitance values are expressed in codes:

Ex. *Resistors Code Practical value 123 12k ohms 103 10k ohms

*Capacitors Code Practical value 103 0.01uF 101/10 100uF/10V

6. ADJUSTMENT6.1 CD ADJUSTMENT

1) Cautions on adjustments• In this product the single voltage (3.3V) is used for the regulator. The reference voltage is the REFO1 (1.65V) instead of the GND.If you should mistakenly short the REFO1 with the GND during adjustment, accurate voltage will not be obtained, and the servo’s misoperation will apply excessive shock to the pickup. To avoid such problems:a. Do not mix up the REFO1 with the GND when connecting the (-) probe of measuring instruments. Especially on an oscilloscope, avoid connecting the (-) probe for CH1 to the GND. b. In many cases, measuring instruments have the same potential as that for the (-) probe. Be sure to set the measuring instruments to the floating state.c. If you have mistakenly connected the REFO1 to the GND, turn off the regulator or the power immediately.

• Before mounting and removing filters or leads for adjustment, be sure to turn off the regulator.

• For stable circuit operation, keep the mechanism operating for about one minute or more after the regulator is turned on.

• In the test mode, any software protections will not work. Avoid applying any mechanical or electrical shock to the mechanism during adjustment.

• The RFI and RFO signals with a wide frequency range are easy to oscillate. When observing the signals, insert a resistor of 1k ohms in series.

• The load and eject operation is not guarantied with the mechanism upside down. If the mechanism is blocked due to mistaken eject operation, reset the product or turn off and on the ACC to restore it.

2) Test modeThis mode is used to adjust the CD mechanism module.• To enter the test mode.While pressing the 4 and 6 keys at the same time, reset.• To exit from the test mode.Turn off the ACC and back up.

Notes:a. During ejection, do not press any other keys than the EJECT key until the loaded disc is ejected.b. If you have pressed the (→) key or (←) key during focus search, turn off the power immediately to protect the actuator from damage caused by the lens stuck.c. For the TR jump modes except 100TR, the track jump operation will continue even if the key is released.d. For the CRG move and 100TR jump modes, the tracking loop will be closed at the same time when the key is released.e. When the power is turned off and on, the jump mode is reset to the single TR (91), the RF amp gain is set to 0dB, and the auto-adjustment values are reset to the default settings.

6.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT

CD CORE UNIT(S10.5COMP1)

• Note :The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mechanism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if the PU unit must be changed, the grating should be checked using the procedure below.

• Purpose :To check that the grating is within an acceptable range when the PU unit is changed.

• 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 taking a long time for track searching.

• Method :• Measuring Equipment• Measuring Points

• Oscilloscope, Two L.P.F.• E, F, REFO1

• Disc • TCD-782• Mode • TEST MODE

• Checking Procedure1. In test mode, load the disc and switch the 3V regulator on.2. Using the → and ← buttons, move the PU unit to the innermost track.3. Press key 3 to close focus, the display should read "91". Press key 2 to implement the tracking balance adjustment the display should now read "81". Press key 3. 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 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 PU 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.• NoteBecause 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.

• HintReloading the disc changes the clamp position and may decrease the "wobble".

6.3 ERROR MODE

- Error MessagesIf 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.

6.4 SYSTEM MICROCOMPUTER TEST PROGRAM

- PCL outputIn the normal operation mode (with the detachable panel installed, the ACC switched ON, the standby mode cancelled), shift the TESTIN IC601(Pin 88) terminal to H. The clock signal is output from the PCL terminal IC601(Pin 39). The frequency of the clock signal is 468 750 Hz that is one 32th of the fundamental frequency.The clock signal should be 468 750 Hz - 10 Hz, + 15 Hz.If the clock signal is out of the range, the X'tal (X601) should be replaced with new one.
