Sorry, but the switch I am talking about is in the 5200 itself on the right rear (as looking from the front) with the square and circle settings. I got this off eBay and the switch was missing. I replaced it with one from radio shack and it didn't work. I'm not sure if the wire was too thick or not, but I wanted to jumper it to channel three directly. I wanted to look at the schematics to see what to wire, before doing it blind.
Thanks
