• How to See Error Code

If a fatal error occurred during adjustment and the adjustment could not continue, the adjustment is interrupted and the error is dis-

played.
[Example]
Error 15		11		35
						DSP error code
		Mechanism error
Service command

This case shows “Focus ON command, DSP error, Sequence interrupted during Focus ON operation”.

• Error Detection at the End of Adjustment

At the end of adjustment, whether the jitter is proper, and whether the adjustment value is within allowable range are judged and displayed as a whole. If all parameters are within allowable range, “Param Chk OK” will be displayed. If parameters out of the range are detected, an error message such as “3 Errs occur” will be displayed (this case shows three errors occurred). Press [lAMSL] controller once to switch the display to the error list.

[Example]
1.		SL		TG		High
						Parameter type
		Disc type

Error No.

This case shows “the track gain exceeds the upper limit in single layer disc adjustment”. If you want to know more details, with the above display, press again the [lAMSL] controller to display details.

Err: SL TG Prm

						Limit value (U: Upper limit, L:
						Lower limit)
		Value stored in EEPROM

Adjustment value

This case shows “adjustment value 7C exceeds the upper limit, and EEPROM holds the last value 3F”.

In this state, rotate again the [lAMSL] controller clockwise, and the judge result message will be displayed as follows:

“TG Too High”

To return to the previous step, or to exit from the error display, press the X button.
