THE FOLLOWING STEPS MUST BE READ AND UNDERSTOOD BEFORE ATTEMPTING TO
COMPLETE THIS MAINTENANCE PROCEDURE.
(A) UNSCREW THE ELECTRICAL CONNECTOR LOCATED AT THE
END OF THE CABLE. CAREFULLY SLIDE THE TOP OF THE CONNECTOR OFF THE
BLACK PLUG. IDENTIFY THE TWO INSERT KEYS AND THEIR POSITIONS (EACH
KEY IS DIFFERENT). HOLD THEM IN PLACE WHILE PERFORMING THE
FOLLOWING STEPS. IF THE INSERT KEY(S) FALL OFF DURING DISASSEMBLY
OR REASSEMBLY OF THE CONNECTOR, REINSTALL THEM IMMEDIATELY IAW THE
CAUTION BELOW.
CAUTION
