Radio Question

My am thumbwheel is set up so when you turn it on it goes to fm, but if you want am you merely turn it off then back on quickly and the radio goes to am. Pushbuttons all work normally. Balance and fader are controlled by tuning in a station and then quickly turning the tuner to one end of the dial or the other. Once there the station you were just listening to will start to play again and you can use the tuner to adjust balance or fader.
