Removing the Module PCB
1.Short-circuit two spots on the land of the pick up FPC. (Fig. 1)
2.Remove the pick up FPC and the relay FFC from the connector. (Fig. 2)
3.Temporarily attach the pick up FPC to the pick up rack. (Fig. 3)
(in order to prevent the damage to the pick up FPC)
4.Remove the two PCB clinch screws and then remove the module PCB. (Fig. 2)
Removing/Installing the Relay PCB
Removing)
1.Remove the relay FFC from the connector
(remove both sides so that the entire FFC will be removed). (Fig. 2)
2.Remove the solder on the lead for the CRG motor. (Fig. 4)
3.Remove the one relay PCB clinch screw. (Fig. 4)
4.Slide the relay PCB to the direction of the arrow and then remove
the relay PCB from the hook A and the hook B. (Fig. 4)
5.Turn the relay PCB over and then remove the SPDL motor FFC
from the connector.
Installing)
1.Check the mecha is in the ejecting state (disc-load suspended state).
When it is not in the ejecting state, apply 4V to the lead (motor) and
then bring it to the ejecting state (4V to the brown line and GND the gray line).
2.Fit the SPDL motor FFC to the connector (back of the relay PCB).
3.Hold the relay PCB so that it does not touch the SW knob as in Fig. 5.
4.Insert it into the hook B as it is a little off to the clockwise direction.
(Precaution) This is to prevent the SW knob from getting into the NG
position as in Fig. 6.
5.Push down the relay PCB lightly and then rotate it to the
counterclockwise direction.
It sets the relay PCB in the hook A and the positioning dowel.
(Precaution) Pay attention so the SW knob will not get onto the PU rack.
(Fig. 6)
6.As in the Figures, while supporting the location A with your fingers,
screw the relay PCB. (Fig. 7 / Fig. 8)
7.Solder the lead for the CRG motor.
8.Fit the relay FFC to the connector.
