I just bought it and wondering how do I turn off the X band. The owners manual does not mention this option but doing searches on the net, I have found places that mention the RX55 having a Band Mod. option to adjust the bands. Any help would be nice. BTW I bought it from a Bel-Tronic's Rep. that is going out of business and it was brand new in the box with the plastic wrap and stickers still on the box. I bought it for $100, still a good deal?
