Selling for a friend so I don’t know to much about this transmitter! All I know is it comes with manual & 2 nano-tech transmitter batteries! I have no idea how old it is but I don’t think it’s had a lot of use. The aux2 switch is faulty but apart from that I believe everything else is fine. Asking $150 I won’t post this ! If you’re interested you will have to come over & check it out in person.
