You should have bought your system from
Sadoun not from others.
Anyway, see the
installation support for BEC 6600+ here:

If your receiver locks, there could be a problem with it. Follow the indtuctions above first and see if that helps.
Try to call or contact the dealer you bought the system from for support.
