I have that coship reciever. Once you set your limits you can tell the reciever to find any satellites it knows about. Hit menu on the remote goto channel search then at the bottom do a search all sat. the dish will the progress from east to west limits and find what it can within its own data list and new stuff(blind search). You may not find everything within the arc.
Next you will have to look at what it found and compare that to say Lyngsat. Use
telstar 5(intelsat 5) as a beginning. If it missed G10 look at the recievers list compared to lyngsat add some of the frequencies it may not have in the list. Position to the far west in channel search on a good canidate frequency and watch for the qaulity and strength bars to peak and turn orange. If you pan from t5 moving west and your limits are far enough you will snag it. try freq(11798) S/R 26660.
I also posted in programming about a great piece of software for updating a plethora of recievers and the 2300 is one of them.
Hope this helps,
Maus.
