Troubles With My Cateye

A while back, I had to change the batteries on my cyclocomputer, a Cateye V2C.  I changed the one in the bike-mounted speed sensor, then changed the one in the detachable handlebar unit.

The Cateye V2C. It's wireless--speed and cadence sensor shown at right.

Cateye’s manual says that when a battery is changed, all you have to do is hit a tiny AC (all clear) button on the back.

So, I did that. But it didn’t work the way it was supposed to. I get the current speed reading — in fact, I get all my currents, including elapsed time and cadence. But currents are all I get.

I don’t get average speed, or maximum speed, or average cadence.

Now, mostly, I’m only concerned with how far I went and how long it took. I’ve got another way to compute average speed. But it sure would be nice to do that on the computer, and have it when I wanted it. Likewise, maximum speed. I have to be watching the thing to get it, and sometimes, I’m just too busy watching the road ahead to look down at the computer and see how fast I’m going.

Cateye’s online site isn’t any help. It features a “Knowledge Base” — a collection of frquently-asked questions and their answers. Of course, they don’t have the answer to the question that I’m asking, which is how do you restore data when you change batteries, and how do you restore the “average” and “maximum” functions — not just the “current?” And they don’t have an email form to ask a questions that’s not in the Knowledge Base.

Does anyone have any experience with this cyclocomputer — or with Cateye generally — that can help me answer my questions?

    I have the CatEye Double wireless and unless our two models are different designs, I swear your rear wheel sensor is installed backwards. In my model CC-RD400DW, The “arm” is supposed to read the sensor on the spokes and the “body” is supposed to read the cadence sensor on the crank.

    Other than that, I could only suggest removing the computer battery and letting it reset completely.

      I found your model’s manual. Ours are different designs, and your computer has more functions than mine like avg cadence. I would try the full reset instead of just the AC button reset. You might want to note the full odometer mileage so you can load that number back in.
