[iMpulseController]

Once the iMpulse has been selected - move to second screen where user holds controller in standard mode and presses 'M'

• BG info screen loads basic setup.
• black overlay at 80% opaque - obscuring screen info
• iMpulse controller is in standard position and showing through black overlay
• 'M' button on controller graphic flashes on and off.
• when user presses M, the black fades away quickly, the correct indicators light up and the controller image flips if necessary.
