I hadn't used my Maestro for a few months because I was waiting on 2.0. After the 2.0 came out, I tried to power on the Maestro and it was completely dead. I was informed to send in my Maestro to Flexradio because its internal battery drained out and it must be sent to Flex. But, my question is this-- Should I have known that the Maestro must be used periodically to prevent the internal radio from draining out? Is this in the directions somewhere that I missed? If I missed it, my bad, I take full ownership. But, if not, it seems like this should have been a big deal to get this information out to Maestro owners. Sorry for the vent, since it is probably my fault for not knowing this in the first place, but it is very frustrating.
