I had a DC 50 collar in my 320 box it stopped tracking i took it out and tried to put it back in with out touching it as i had cast the hound. The box will let me put it in but it want let me start tracking until i put the pin number in i did not have a pin number in it as i bought the collar used. It was working in my box for severasl weeks now it has stopped. My question is how can i get it back into my box. I will have to catch the hound first hope she stays with other hounds.
