connector by the housing. Then hold the adapter connector on the
cable itself next to the sliding connector housing and push the two
connectors together. The two cables will lock together when prop-
erly connected.
Note: To disconnect the cables, hold the both cables by the housing and pull apart. The
sliding housing on the adapter cable connector will release the lock and allow the
cables to be separated.
