[TenTec] Eagle Firmware version

[Michael A. Goltz]

Hello to all.
I have a new Eagle. Here are a couple of "new owner" questions--
I just received the rig from Ten Tec a few days ago. I love it and I have learned the menu functions pretty well. It blows away anything I have ever used-- (CW at my QTH forever!).
I am curious-how do I tell what software version was factory installed? Or what software version it is currently using? Or am I unable to see it (?)
Another query- I am tempted to leave the software alone. Is there a great advantage to upgrading to the latest software version? Should I care one way or another?
I don't want to make an error  and "brick" my new radio! I saw on another Eagle user group where a guy did just that. I am pretty computer literate but all it takes is one wrong move!!
Thanks for any responses. Either here or off reflector would be appreciated!
