After calling and speaking to Doug regarding a failed firmware updateon my MZ-24, it was fixed rapidly but afterwards, when I bound my transmitter to a 12 channel receiver, I shut the receiver off and then the transmitter. When I then turned the transmitter on, there was no reset button at the bottom of the pop-up screen. Doug called back moments after I put in the call and after troubleshooting, determined we should do a factory reset. I guess I was a little heavy on the fingers and the result was me having to send it in for repairs. This guy has been a pleasure to deal with and I give kudos to the Graupner USA team.
