If you have 2 625 boxes you are charged the extra $5 a month because you have 2 receiver. Go by the boxes themselfs, less confusing. There is no way around this fee, you would be charged this fee for ANY 2nd reciever. All the dual tuner models are required to be plugged into phonelines if you want the $5 phone fee waived. Thus if you didnt have the 625 boxes connected to the phone you would be looking at an extra $15 a month fee.
