To ensure the tilt mechanism is operating correctly.
Put the player in the following condition:
- Service mode
- Tracking loop close
- Tilt servo 10:off
Ensure that the tilt connector CN4 is connected.
Play the test disc in service mode with the tracking closed.
Turn off the tilt servo and use the CHAPTER SKIP FWD or CHAPTER SKIP REV keys on the remote control to set the tilt to 0D.
Turn the tilt servo on.
Confirm that the tilt value returns to 10 (the range 0F to 11 is within tolerance).
