Handling the mechanical module
1. The mechanical module should be handled by holding
the upper frame and main frame of the mechanical
module.
2. The front section of the upper frame is not very sturdy,
so this section should not be held too firmly (see fig. 1).

Removing the DVD Core Unit R
1. Bring the mechanism to a locked position (disk load
standby position).
2. Turn the mechanical module upside down.

the land end (the other is auxiliary), and turn the SW
knob in the direction opposite to OP (see fig. 2).

cable from the connector. Remove the solder on the
lead wires of the load motor.
5. Remove screws at two locations, and remove the DVD
Core Unit R (lift the board in the direction of the white
arrow shown in fig. 3, and remove it out diagonally).
Do not hold onto this area.
