[A change in parts]
No. : CX-205
CONCERNING THE ADDITION OF A
PROTECTION NETWORK TO THE ADF
RELAY PWB.
1.Model Name: JX-AF3
2.General: If the ADF’s connector is accidentally attached to the JX-330’s FSU connector, the
ADF’s solenoid goes on permanently. The heat which results may melt the cabinet.
Therefore, we have decided to add a protection network to the ADF relay PWB.
As a result of this change, the metal cable holding ring is no longer necessary and will
be discontinued.
3.Description: 1. Changes to the ADF relay PWB unit as a result of the addition of a protection network.
