Push up with your nail, or something soft.
Do not use thin tools such as the tip of screwdrivers, because
they will damage the electrode.
Insert the flexible cables straight until the end.
Insert the flexible cable reinforcing plates in parallel to the
connectors. Moreover, insert the horizontal-connecting
connectors horizontally.
In connecting Address Modules and Cable Assy, and in
connecting Scan Modules and Y Drive Assy with the flexible
cables, hook both edges of the flexible cables on the connectors
and fix them, then close the covers.
Insert the flexible cables in parallel to the connector, otherwise
the connectors may be damaged.
