I give up. The C300 has two meters. There is only one that you can reset. The internal clock is like an odometer, it cannot be reset. The other is like a trip meter, you can reset it. I can find the trip meter and reset that as needed but how do I read the odometer?

Phil, cycle thru the info pages using STATUS button on the side of the camera. If I remember, the hour meters are on page 7 of 9, or thereabouts.

You are totally right! I thought STATUS just showed one thing. Nope. It's pages long.

Pete and @dvinfo saves the day!
