HI, just bought a Echostar T-105 box, and I need to turn on the rf output to allow me to feed the signal around the house via me aerial distribution amp. This box has replaced my Pace on-dig box which used to have an rf o/p. However the option to turn on the UHF o/p is disabled in the setup menu, Echostar says it can be turned on via the engineering menu, but wont give me the instructions on how to do this. Any suggestions? Thanks in advance.
