I noticed recently that if my Varia was working -- light and radar -- and then I ended my ride and powered off the Edge 1030+, the light turned off. Does the Varia go into some sort of "sleep mode" or something under certain conditions such as the Edge disconnecting? Or should I make sure to explicitly turn it off when i'm done riding?
I've been using this gadget for a few years now and have apparently forgotten all the details about how the think works! Still does great at radar detection though.
