As far as I know, there is no way to turn the screen off. Screen-wise, there are two things you can do to minimize battery drain. One is to make sure that the backlight is dialed all the way down. The other is to make sure that you leave the unit set to display something other than the map. This is the because updating the map page requires a lot of CPU cycles, particularly when you are set for track up. A lot of people seem to use the "trip computer" page since it can be configured to show a lot of useful information. Disabling the on-board compass also conserves the battery, as does disabling WAAS. Thanks a lot for the useful tips Tom. I'll take care of that. Cheers, Andreas.

I'm talking about tracking in the field - not tethered to a PC. When you walk for hours and you know the way, there's no need to have the screen on, though you might want to track the path anyway. For me, that's a waste of battery life. Thanks for the answer ... Andreas.

Hello! Is there a way to have the Colorado 300 track a path without the screen on. I don't need to have the screen on all the time but didn't find a way to turn it off and still have the tracking on. Maybe someone can give me a hint. Thanks ... Andreas.
