5.2ERROR CODE LIST

-Error Messages

AIf 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

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.

B	<Direct FUNCTION keys and corresponding functions>
	Direct FUNCTION key	Normal mode	Slave test mode

• For convenience, a name of each direct FUNCTION key is shown as "A", "B", and "C".

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 :
	Measuring Equipment	Oscilloscope,Two L.P.F.
	Measuring Points	E, F, REFO1
	Disc	TCD-782

		100 kohm
		Oscilloscope
	VREF	390 pF
	F	100 kohm
	VREF	390 pF
D		L.P.F.

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.

E4. 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".
