How do I change the time and set favorite radio stations in my 2002 Mazada 626? I just got it and it does not have a manual!

presets: go to station desired and push and hold for 5 seconds or so the numbered button you want that station to be. You should hear a beep or an audible sound or some kind of confirmation. Clock: push and hold clock button while simultaneously pushing an arrow button like scan or seek.
