Charlie, you will have to delete the channels by satellite. Quite easy to do.
Got to the SETTINGS menu, DATA RESET, press ok and if it requests a password, type in "0000". Scroll down to DELETE SATELLITE CHANNELS and press OK.
The entire satellite list will be pulled up. Scroll through the list and put a CHECK MARK in the box preceding the satellite that you want to delete channels from.
Once you have all the sats checked off that you want to delete channels from, press OK.
You can follow the prompts from there. This will only delete channels from one sat at a time (or as many as you check off). Then, you can return and rescan the
sat with the selection to scan for FTA channels only. Uncheck the box for RADIO and ENCRYPTED channels if you wish to scan for FTA TV channels only.
No way to do it TP by TP. You can delete channel by channel which is fine if you just want to dispose of one or two channels, or sat by sat. The only way to delete the channels by TP is to delete the TP and you really don't want to do that.
