First, let me give you a statement:
Houston: You are clear to hook up lunar equipment conveyor.
From the above, you can tell:
"clear to" means
"you are authorized to, you are permitted to, you have the permission to"
"hook up" just means
"to make connection, to broadcast over a radio network"參考資料： self
