I have had my Dronemods uav locator for one year and two days. Just renewed my plan a few weeks ago.Yesterday I turn it on and have it in my van. All seems normal. Some hours later I noticed it was off. I could never get it to come back on. I put in on charger and it does the normal thing. If off putting it on charger turns unit on plus charging. I didn't want to take it apart thinking that so close to the one year warranty they may do something for me. I emailed Bob at dronemods about an hour ago but no answer yet. I;m thinking maybe the battery took a dump. Anyway I'm thinking there must be a reset button somewhere. THERE IS. It is under the sim card cover. A tiny hole. I used a round tooth pick and poked and when I felt the click I was happy. I called it and when I received the text, it shows my battery at 100%. This has never happened before. I will say this. It was under my windshield in the sun. I wonder if that had any affect although it's been there many times before.
