How to recognise it
Four round buttons in a row, a small display above each one and a coloured lamp per button. New in the MAYDAY update; which campaign levels use it is not documented yet.
Procedure
Press one button at a time, counting every press out loud ("button two: one, two, three"), and wait for the deaf player's "good" before the next button.
Common mistakes
Pressing fast and losing count. The display is the truth, let the deaf player read it.
Solver
Enter what you see on the bomb and get the action for the current state.
