Its a model 1425 dual res and I would like a manaul that shows how to set it up before i go monkeying with it...thx for any links or pdf's you may have 
I have one. It didn't come with a manual, just a video connector ending in bare wires. All I did was match up red to red, green to green, etc. on the connectors. Then I did trial-and-error on the sync until it worked.
