resetting clock on 95 Caravan

I have a 95 Caravan with no owner's manual. I would like to reset the clock, but don't know how. Also, clock is starting to run a few minutes slower than it was a couple of months ago. Isn't it tied to the battery? If so, why would it be slowing down?

Look for 2 holes the size of a paper clip on the face of the radio. Use a ball point pen to set the clock.

If you have the Infinity Radio without the H & M buttons, try this:
Push the "Set" button, like you are setting a radio button. Then push the "Select" button. You will see a clock display with flashing hour. Use the "Tune" (radio station) control to scroll to the correct hour. Then push "Select" again to flash the minutes. Use the "Tune" control again to scroll to the correct minute. Then push "Select" again. You are done.
