[QUOTE="jeallen01, post: 1111152, member: 176704"] It's always best to switch the receiver OFF when connecting anything, but if you don't then there is a[I] slight[/I] chance of causing the receiver o/p to close down (but it will recover if you then switch it OFF and then ON again) because you accidently shorted the end of the cable from it. However, I have rarely had that happen, and it didn't to the SX88 in our "office" when I fixed the earlier-reported problems with the LNB cable i/p's to the 16-1 switch from the 2 dishes where I had either no or very low signals - disconnected and reconnected each of the cables several times with no problems before I finally fixed both. [I](It's a 40m roundtrip, plus the house stairs, between the SX88 and the DiSEqC switch, and I didn't want to have to do that every time I disconnected/reconnected one of those cables!)[/I] What you must do before connecting an LNB cable to the DiSEqC switch is to make sure that there are no strands of the braided screen trapped between between that screen and the bare core of the cable inside the F-connector, and that the core itself is dead-straight and centralized in the plug so there's no likelihood of it bending and shorting the switch i/p F-connector. PS: you won't "fry" the LNB if the o/p of the receiver or switch is shorted because that will simply remove any voltage on the LNB i/p! [/QUOTE]
