Inner-switch or sledge motor problem.Sledge Out ErrorThe sledge did not come out of its inner position (inner-switch is still open) before approximately250 mSec. have passed by. Inner-switch or sledge motor problem.Jump-offtrack errorTriggered in normal play when the jump destination could not be found within a certain time.When this error occurred, software will try to recover by initiating the jump command again.If it is recoverable, the disc will continue to play.Subcode ErrorTriggered when a new subcode was missing for a certain time during play.PLL ErrorThe Phase Lock Loop could not lock within a certain time.Turntable Motor ErrorGenerated when the CD could not reached 75% of speed during startup within a certain time.Discmotor problem.Focus Search ErrorThe focus point has not been found within a certain time.The carousel switch is not open within certain time. This can happen when either the switch isdefective and closed all the time, or when the carousel is blocked when located exactly at adisc position.The carousel position switch did not close within a certain time. This can happen when theswitch is defective and never closes electrically, or when the carousel is blocked in betweentwo disc positions. The time-out is approximately 5 Sec.The drawer could not enter the inside position is opening again. This can be caused becausethe drawer is blocked by something and cannot go fully inside, or the drawer switch is defectiveand does not close.STANDBY-ONButton pressed?YNSet is in Service PLAY Mode.The Service Play Mode is intended todetect and identify the failures in the CD Mode.In this mode the electronics will still functioneven when an error is detected so thatrepair activities can be carried out.SERVICEPLAY MODEIn case of failures, errorcodes according to Table 2 will be displayed.Variousother TestsActivated with ACTIONTESTQEEPROM FORMATTESTLoad default data.
