5.2 ERROR CODE LIST
- Error Messages
A
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
(minutes display area) and DSEC (seconds display area). The same data is written to DMIN and DSEC. DTNO
remains in blank as before.
B
Depending on display capability of LCD used, display will vary as shown below. xx contains the error number.

A
During pressing the "SOURCE" and "RPT" keys simultaneously, perform the reset-start, then turn ON
the CD to enter the CDS test mode.
• How to issue the 1 - 6 keys in the 08 model's slave test:
The specification of the 08 model does not include the 1 - 6 keys issuance function for H/U and the remote control unit.
Therefore, in order to issue commands in a slave test, use the direct FUNCTION keys alternatively to enable the equal
key command sending function to the existing models.
Outline) Use the direct FUNCTION keys to display, select, or issue the KEY 1 - 6.

8.2 CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT
A
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.
B
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 :

Checking Procedure
1. In test mode, load the disc and switch the 3 V 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.
E
4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase
difference is within 75 degrees. Refer to the photographs supplied to determine the phase angle.
5. If the phase difference is determined to be greater than 75 degrees 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 degrees 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
Reloading the disc changes the clamp position and may decrease the "wobble".
