(c) If the spiral cable sub-assembly stops rotating and the connector has moved past the bottom, return the connector to the bottom as shown in the illustration.

(d) Rotate the spiral cable sub-assembly clockwise approximately 2.5 times to move the connector from the bottom to the top.

NOTICE:

If the connector is rotated clockwise from the bottom 5 times or more, the spiral cable sub-assembly may be damaged.

Clockwise

(e) Check that the spiral cable sub-assembly is center position. Text in Illustration *a Check Window *b Matchmark *c Top of Flat Cable U-turn OK: The connector is at the top. The matchmarks are aligned. The the top of the flat cable U-turn can be checked from the check window. HINT: If the spiral cable sub-assembly cannot be centered, it is possible that the spiral cable sub-assembly is broken. Replace the spiral cable sub-assembly with a new one.
