USING THE ATC CHAMELEON
The very first thing you should do is head over to the official Oregon Scientific support page to download the latest PC/MAC software version (unfortunately Oregon Scientific hasn't updated either the FW or the PC/MAC software till this day).
As you can see from the above pictures the software is very simple and easy to use since it just playbacks the files found in the ATC Chameleon. However to be completely fair it does allow you to switch between streams and setup the screen according to your preference.
