I have had the unit for about 2 weeks now. When I first got the unit I plugged the transmitter in to charge and had no issue. I have used it twice for about 2 hours each time since then with no issues. I went to charge it again and now it wont charge. I have made sure that I am plugging it in all the way and used a flashlight to check that nothing made its way in to the 1/4" jack. When i plug it in to the G10S the whole unit acts identical to when it is plugged into a guitar. The transmitter lights up solid green, the wireless signal strength gives me 3 solid green lights, and the battery level indicator gives me 1 solid green light. After 4 minutes the transmitter goes to sleep. I have only used the 9v power cable that came with the g10s to power the unit (with the exception of right now when the unit is powered via USB from my computer.) I successfully installed the latest firmware into the G10S base, but the computer does not see the G10T transmitter. It also may be worth mentioning when not in use I always store the G10T in the G10S by pushing it all the way in then pulling it out one click so it is held in there securely but not trying to charge the entire time and I do not leave the G10S unit powered up all the time, only when in use. Where should i go from here?
