*Remove two screws at location of orange arrows above.
*Remove the modem module itself. It will pull directly up
*Insert new modem carefully into board, pushing down until seated all the way
*Re attach antenna connection
*Add rtv around antenna connection to keep it from coming off

At this point, the DCT or EDR can be re-assembled and tested.
