They all do that...
Just perform a 'Test' to verify Iridium connection and subscription status before you go - Every Time! (just like the screen tells you to do)
Well, the device would not turn on without external power. Meaning, I get to the above screen and no commends accepted when disconnected from house power, I upgraded to the 4.2.. firmware release and all is good. The 4.2 release notes state, among other changes, that the "Turn On" function has been removed, which I can verify that is the case. So, the upgrade worked and the device is functioning per specs. Thanks
