You switch the radio on, then use the toggle button (which changes the tracks on a cd) to the 1st number and press mute this then moves u onto your 2nd digit, again use the toggle button and press mute this puts you onto the 3rd digit and then do the same for the forth. When you have entered the last digit keep the mute button pressed until the digits have stopped flashing. You will need to enter your code everytime you disconnect your battery !
