- Go to advanced install then of course choose tuner 1 as there is only the one tuner installed.
 
- Then move up/down and highlight the satellite you wish to modify.
 
- Next look at the very top of the screen you will see TP List -- Sat List -- Edit Satellite- Using your double arrowed left and right keys on remote move to TP List.
 
- At the bottom of screen you will see the color blocks, press the green key on the remote to "add a Transponder".
 
- Enter the required Transponder info and then press ok on remote to save.
 
- With that transponder highlighted press the red button on the remote to scan only that one transponder.
 
You will also see from there I think how to edit transponders, delete them, etc.
Hope this helps, and gets you in the right direction.
