6.3.3 How to Playback a Disc in Test Mode
In test mode, since the servos operate independently, playing back a
disc requires that you operate the keys in the correct order to close
the servos.
Here is the key operation sequence for playing back a disc in test
mode.
Lights up the laser diode and closes the focus servo.
Starts the spindle motor and closes the spindle
servo.
Close the tracking servo.
Wait at least 2 – 3 seconds between each of these operations.
