Needs Help regarding Airtel HD error b001

[waheedaup]

Assalam o Alikum,

Dear I have reconnect my Airtel Digital HD receiver after one year and for this purpose I have installed the dish at SES 7 Satellite at 108 degree East and I have received 85% Signal Quality on my Neosat 9900 HD Spectra Satellite Receiver after that I have connect the same cable with Airtel Digital HD receiver but here I found no signal and error show B001. I again disconnect the Airtel receiver and connect the cable again with Neosat 9900 HD Spectra receiver and found the signal quality 85% again. What is the solution of the error no. B001 on Airtel? Any body can help me in this regard?
