hahaha i think what you mean is, how do you set the certain sections once you set it right?
So you go to clock mode.
push and hold down the button, yes, theres only one... you cant miss it.
it'll start blinking, then you just keep pushing until you're happy with the number.
leave it idle for abour 3 seconds, and it'll jump to the next spot.
so if it was on hours, and you set the hours, wait a bit, and then it'll go to minutes.
