After updating (my airtel stb is not uses from last 6 months)
I have found in menu section, there is FTA channels tuning facility.
what I have done
Reliagn dish towards 93.5*E (DD Direct)
find FTA channels
satt. INSAT 4B change the module from dvb s2 to dvb s
press green or blue button ( I don't remember it, u will see the color button in for search/find, and save option)
all the free channels are saved after channels no 1499(mean u will c all 59 + radion channels)
and after saving.
the problem arise.
U will c NO SIGNAL in any channels (from channels no.1500 to ....)
When I call CC they are asking for Customer Name (which is resisted with) and I don't know the name of person, who have given me the box.
If any one try it will find the soulution.
