Go to MENU > HELP > STB INFO > SETUP > HOME FREQUENCY > OK ...... Now use remote channel up down arrow keys for scroll up & down and volume side keys for satellite shift between NSS6 & ASIASAT ...........
these signals are very good channels will work smoothly and 1 TP which has 2/3 singnals i think thats 11172 V 27500 which is now changed to 11172 H 30000 .... So that 1st frequency has no channel so don,t worry abt that freq....
