We had a new pace box fitted today to replace a faulty refurbished pace box. As well as this, the engineer fitted a new LNB thing to the sky dish (I apologise, I don't know the name of what he fitted exactly). Anyway, after he had done this, and sorted out all the installation for the box, he checked the RF outlet in the engineers menu. It has always been 38, so he left it at that, but he choose the ON option for the "RF Outlet Power Supply". I know for a fact that this was off before he arrived. He turned it on for some reason. I was wondering what this option is, and what difference it makes having it on or off? We have a second box in the house, but that still has the RF outlet power supply as off. Any help would be great.
