When we picked up my wife's bike, it came with a blackburn Delphi 4.0 bike computer. Unfortunately, no matter what I've tried for button presses, the timer will never start, it will never display any speed information , cadence information, or anything. All I can do is set the clock.
I've tried resetting it, and pressing every button combination I can think of, and nothing. The manual doesn't allude to what to do in this situation, so I'm at a loss. Anyone able to help before I this thing and just get another one ?
