Section 8 - Cable Specs
OK OK OK. Here are the cable specs. They are 100% correct. Of course I
wouldn't know because these are for information purposes only. I have been
told however by VERY reliable sources that they are guaranteed, 100%, GRADE-A,
correct. If they don't work for you, you did something wrong.

By the way, Jakey told me to remind you that the handset can NOT be plugged in
while this cable is hooked up.
