Nova 2 game help

Hello I am playing the NOVA 2 game and I am stuck in the elevator. The enemies have a jamming device that does not let me go up in the elevator. Does anyone know how to destroy the jamming signal? I can't find it. Don't know where it is. Please help. Thank all of you very much.

There is a machine on a platform, about the same hight as you, use your EMP on it. (shoot that abillity at it!)
