Error Description

Focus Error
Triggered when the focus could not be found within a certain time when starting up the CD
or when the focus is lost for a certain time during play.

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

Sledge In Error
The sledge did not reach its inner position (inner-switch is still close) before approximately
6 Sec. have passed by. Inner-switch or sledge motor problem.

Sledge Out Error
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.

Jump-offtrack error
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.
If it is recoverable, the disc will continue to play.

Subcode Error
Triggered when a new subcode was missing for a certain time during play.

PLL Error
The Phase Lock Loop could not lock within a certain time.

Turntable Motor Error
Generated when the CD could not reached 75% of speed during startup within a certain time.
Discmotor problem.

Focus Search Error
The 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 is
defective and closed all the time, or when the carousel is blocked when located exactly at a
disc position.

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.

The drawer could not enter the inside position and is opening again. This happen when the
drawer is blocked and cannot go fully inside or when the drawer switch is defective and does
not close.
