Can’t figure out how to use

So a friend bought a Mac pharms disposable and for the life of us we can’t figure out how to use it. We hold the button and it lights up either white green or blue (color changes when hitting the button 3 times) if we press it twice it blinks red a few times then goes solid red. If I press it five times it blinks 5 times and locks. It’s fully charged and hasn’t been hit a single time.
