You asked: 'Nadin Nyla, I didn't use my Pansat2700a for last 10 months.Can you tell me what files do I need to load to receiver? and which sites I can get all files? Thank you so much for helping.'
If it is showing b-75 when you turn it on, then load the latest 294 BIN using 27.02 Loader.
Otherwise or just for being very prescise, load the factory file 124 first and then the 294 BIN.
