6.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT
 • Note :
   The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mecha-
   nism 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             • Oscilloscope, Two L.P.F.
 • Measuring Points                • E, F, VREF
 • Disc                            • ABEX TCD-784

 • Checking Procedure
 1. In test mode, load the disc and switch the 5V 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 adjust-
    ment 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 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 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.
 • 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
   Reloading the disc changes the clamp position and may decrease the "wobble".

7. GENERAL INFORMATION
7.1 DIAGNOSIS
7.1.1 TEST MODE
- Error Messages
     If 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 (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.

Remarks: Mechanical errors are not displayed (because a CD is turned off in these errors).
         Unreadable TOC does not constitute an error. An intended operation continues in this case.
         Upper digits of an error code are subdivided as shown below:

- New Test Mode
     S-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 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 key.
2 Select S-CD for the source through the specified procedure including use of the [SOURCE] key, and inserting the
     disc. Then, press the [Jump Mode Selector] key while maintaining the regulator turned off.
3 After the above operations, the new test mode remains on irrespective of whether the S-CD is turned on or off.
     You can reset the new test mode by turning on the reset start.

- How to hold the Mechanical Unit
1. Hold the top and bottom frame.
2. Do not squeeze top frame's front portion too tight,
   because it is fragile.




                                                                             Do not squeeze.


- How to remove the Top and Bottom Frame
1. When the disk is "clamp" state, unlock Spring A (6                                          Top Frame
   pieces) and Spring B (2 pieces), and unscrew screws
   (4 pieces).
2. Unlock each 1 of pawl at the both side of the frame,
