1-12. Cables to Handle with Care
1-12-1. Disconnecting/Connecting Flexible Cable (FFC, FPC)
Note
•Be very careful not to fold flexible cables. Life of flexible cable will be significantly shortened if it is
folded.
•Each flexible cable has conductive side and insulated side. If the flexible cable is connected in the
wrong orientation of the conductive side and the insulated side, the circuit will not function.
•Check that the conductive side of the flexible cable is free from dirt or dust.
•Do not open the locking tab excessively at an angle above the value shown in the figure to prevent
the connector from being damaged.
Note
The following cables are referred to collectively as flexible cable in this manual.
