Hello I had a question regarding the operation of the Terra TMA 340 D. I’ve never used this system before and I’m having trouble finding information online regarding its operation. My question is in regards to the com 1, com 2, and auto switches, when com 1 and com 2 are in the up position does that mean we will be able to transmit and receive through both of them and what is the purpose for the AUTO switch. Thank you.
