Dumb speed sensor it toast. I replaced the battery in the computer and it kept beeping and pausing--no display of distance/speed. Apparently *I* can't replace the battery in the sensor so I'll have to send it all back to Polar. That will take at least 2 weeks repair time PLUS there's no warranty. I've only had the computer for 1 1/2 years. Gah!

I used to have a Cateye and I am really thinking hard about going with another computer.
