108MHz Sledge Out Error
108MHz E1003
The sledge did not come out of its inner position (inner-switch is still open) before approximately
530kHz 531/530kHz* 250 mSec. have passed by. Inner-switch or sledge motor problem.

E1005 Jump-offtrack error
Triggered in normal play when the jump destination could not be found within a certain time.
560kHz 558/560kHz*
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.

87.5MHz 98/87.5MHz*
Discmotor problem.
E1020 Focus Search Error
The focus point has not been found within a certain time.
E1070 The carousel switch is not open within certain time. This can happen when either the switch is
defective and closed all the time, or when the carousel is blocked when located exactly at a
disc position.
E1071 The carousel position switch did not close within a certain time. This can happen when the
switch is defective and never closes electrically, or when the carousel is blocked in between
two disc positions. The time-out is approximately 5 Sec.
E1079 The drawer could not enter the inside position is opening again. This can be caused because
