I'm going to revive this thread a little bit. After Arthur sent me the 501 I kinda went mute, that in part had to do with school and a little bit of me just wanting to fool around with the thing. The ktu works perfectly, had a little snag at the biginning where i wired it so the lamp voltage was going where the battery voltage was sopposed to, but after that it was smooth sailing. So one of the things i'm getting for the ktu is a 400h. After what chris said I hesitated to get one, but after reading that you have to WAIT 2 seconds before pushing hold, I just thought I'd give it a try. ( the pdf I read: the pdf , look at page 7 at the bold text.). So when I get those in I plan on getting a video posted on the ksu. My desk at the moment with my phones and all my desk . Currently the ksu is connected to my Panasonic easa phone 308, my xlink, and a tda 50 pbx that's slightly broken (it crashes when it gas more than 4 phones connected, hey it was free!). so ill keep this updated. bump
