Notes:
To protect the mechanism from unexpected damages, keep the following points in mind:
1. Before moving the CAM motor from the ELV position to the LIFT position,
be sure to move the ELV motor to select the disc 1 to 6.
2. Before moving the CAM motor from the CLMP position to the LIFT position,
be sure to select the SPDL claws to release the disc clamp.
Note:
The mechanical operations such as loading, ejection and disc change are controlled by the highly sophisticated method.
Before entering this test mode, fully grasp how the mechanism is controlled, by referring to the mechanism operation flowchart.
Note:
Before moving the ELV motor, be sure to move the CAM motor to the ELV position or LIFT
position first. If not, the mechanism may be damaged.
When the CAM motor is set to the ELV position, do not move the ELV motor from the
door open position to the door closed position.
