My uncle gave me his old Centurion Sport DLX that was hanging in the garage, and it has a cateyemicro cc-6000 cyclocomp on it. I popped in a fresh battery and everything functions according to the manual I found here. The manual tells me how to do EVERYTHING with it EXCEPT how to power it on and off. I let it sit for a couple of hours, no dice. I tried holding different buttons and still no luck. Anyone know how to turn the darn thing off??
