Hi! I bought a preowned Invisible Fence model ICT 802 and it has taken me all day to get the wiring installed and the transmitter to perform properly for the most part. I have one BIG remaining problem. I can increase the distance between the wire and the warning beep, but the shock is happening simultaneously with the beep (6 feet out from the wire). Is there a way to fix this, a setting adjustment that I'm missing, anything? Why would the shock be happening 6 feet out from the wire simultaneously with the beep? It obviously can't be used this way, because there is no warning for the dog, just immediate shock/beep. This is supposedly a newer model, titanium computer collars (I have two). Any advice is appreciated. I have $550 in it so far! Thanks, Susan
