I'm kind of green when it comes to the TSC7 so please take it easy on me. lol. My guy in the field is using a TSC7. He has dumped a few point files onto our server. When I look at the data all seems fine. He is telling me that the TSC7 is showing a (m) behind the elevations. I'm assuming this means meters. He said if he tries to change it the controller automatically reverts back to the (m) meters. What could be causing this? How should I fix it?
