How to configure a bike computer?

Question

I have an old bike computer and can't remember its brand or how to configure it.  The logo on it is a black triangle (like a pyramid) with the symbol of a man on a bicycle in the center but slanted upwards to the right.

It has an LCD screen with 2 large round black buttons below the screen, and the logo between the buttons.  It uses a thick but small button sized battery with number L1142.

It's a basic bike computer bought from Target about 6 years ago.  I accidentally reset it while preparing for a ride and now can't remember exactly how to re-configure it.  The specific piece of information that I need to enter is something like the wheel size in centimeters or something like that, or else it won't accurately measure speed and distance.

I need this information tonight because the NYC 5 boro bike tour is tomorrow!!!

Thanks very much.

Try this site, the little guy on a bicycle is common on several different makes.  Try the Schwinn 12 function cyclocomputer settings.  If you press both buttons for 4 seconds it should reset to 2124.  Use the right button to change the number and the left to move to the next digit.  That is the circumference of the wheel in mm.  Check the chart for your tire size.  Next is the selection between kph and mph, the right button switches between the two and the left sets it.  After that it goes to the time hold the left button down for several seconds then select 12 or 24 hr mode.  Then set the time.
