Cant change time

Usually, there is a "disp" button that you press to see the time instead of the station. Try holding this button down until the display shows the time blinking. If this works, you can change the hour with the "<<" button and the minute with the ">>" button. If this did not work, and your unit displays the time while it is turned off, try the same thing with the unit off. Let me know if this helps :)
