Ben is correct, you need to cut the strap, it is labeled HHEU and whoever sold you the BHEU or installed the BHEU should have told you to cut the wire or cut the wire themselves.

A small scissors will do it, just make sure the wires don't touch. Don't cut out a big section in case some time you want to remove the BHEU and move it to another phone. You will have to solder the wire back in place to use the phone normally.
