just hear i think its revision number is 221, bc when u enter test mode it shows dd on the screen, and bc the twisters are in hexadecimal in test mode, so: dd=221 For test mode irl: just turn both dials to lightning, then set the mode dial to off, then hold hit it, while holding hit it, turn it on!, hit it to cycle through the 5 tests!
