is lost for more than a certain time during playing of CD.
Radial Error
Triggered when the radial servo is off-track for a certain time during playing of CD.
Sledge In Error
The sledge did not reach its inner position (inner-switch is still close) before approximately 6 seconds
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 250ms
have passed by. Inner-switch or sledge motor problem.
