How do you set the clock on a pioneer super tuner III car stereo?

Turn system on with only clock showing Press and hold "A" audio button till hour starts blinking the rest is easy too work out. More info such as how to make each diget go up or down in value as well as zero to the real Time Clock on my watch set by Fort Collins Radio Signals

Just a note: To set the clock on mine you need to hold the audio button along with the function button then the clocks starts flashing. Then just use the up and down button to change time. To go from hours to minutes keep holding on to the audio button and press the function button again this will flash the minutes.
