I just purchased a like new Verizon QIP 2500-1 from an estate auction. I am currently a subscriper to fios and signed up for 4 cable boxes that are included in my monthy bill. I would like to conect this box to another TV in my home. I have several concerns: Can I do this myself or must I have Verizon come out to do the install and activate the box. If I can do this will there be any additional monthly charges.
