I had to switch out a spirit KSU its a 308 with a 308 expansion, all works fine but it pulse dials not tone. I slide the admin switch to admin then hit the intercom then speaker then *0 hear 2/3 beeps then hit feature and got error tone, hit 7 got error tone try hitting line 1 and error slide the admin switch back and still pulse dials help what did I do wrong
