1) Does the fan run 24/7? It is in my bedroom and would love to turn it off at night. 2)How do I activate the 30 second skip? Is this something I can do once or does it constantly need to be done? 3) The installer had to install a 3X4 multi-switch to my triple dish. I have 5 lines running into the house. The lines coming out of the new multi-switch are not always acquiring signals for all channels. I turn off the units and come back later and no problem. Sound like a bad Multi-Switch?
