I'm not sure if it is just a random coincidence, but after using the my Carlson surveyor plus in GNSS demo mode, and forgetting to switch back (threw me in a major loop - setting base/rover/radio repeatedly) my internal radio on my Triumph 1 base will no longer turn on and begin transmitting. I have several Triumph 1 Units that behave similarily - they have been well used - could this be a internal battery issue? Or could it have something to do with switching in and out of demo mode? I appreciate any ideas. Thanks.
