E1001
Radial Error
Triggered when the radial servo is off-track for a certain time during play.
E1002

E1003
Sledge Out Error
"USA"
"OSE"
The sledge did not come out of its inner position (inner-switch is still open) before approximately
250 mSec. have passed by. Inner-switch or sledge motor problem.

E1005
Jump-offtrack error
108MHz
108MHz
Triggered 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.

E1020
Focus Search Error
87.5MHz
The focus point has not been found within a certain time.
98MHz
The carousel switch is not open within certain time. This can happen when either the switch is
E1070
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.
