Chapter 1 Your DVR should not be used with a digital PBX phone system. Doing so may permanently damage your DVR's modem and will void your warranty. Digital PBX phone systems allow many phones to share a single telephone number and are usually used in hotels and office buildings. If you are installing the DVR in your home, it is very unlikely that you are using a digital PBX phone system. If you have a Single LNB satellite dish antenna, you will need to upgrade to a Dual LNB for full functionality. Contact your satellite dish antenna manufacturer for more information about upgrading. 2 Connecting Overview Television used to be so simple: all you needed was an antenna and a TV. The antenna captured audio and video signals and sent them to your TV over a wire. As TVs have acquired more features, and new devices have been created to work with your TV, it may seem that everything has become more complex. You may have a VCR, a DVD player, and a game system connected to your TV, in addition to your DIRECTV® DVR. However, one thing has remained the same: you still need to get audio and video (sound and pictures) from their source (your satellite dish) to your TV. Connecting to a Phone Line Your DVR needs to be connected to a standard analog phone line to communicate with DIRECTV. The DVR occasionally makes a brief phone call to get updates to the DVR service and for pay per view functionality. You do not need to install a new telephone jack or phone number for the DVR to work; it can detect when your phone line is in use and will only make calls when the phone line is available. If you don't have a phone jack nearby, you can use the 25 foot phone cord that ships with the DVR. If your phone jack is being used for a phone, you can use a phone splitter (not provided) to connect both the phone and the DVR to the same phone jack. Connecting a Dual LNB or a Multi-Satellite Dish Antenna Your DVR comes equipped with two jacks for satellite input. Connecting both allows you to record from two channels at the same time (see Dual Tuner on page 5). All of the connection examples in this chapter give instructions for configuring the DVR with connections to both satellite input jacks. Both a Round Dual LNB dish antenna and an Oval 2 or 3 satellite dish antenna connect to at least two Coaxial RF cables. To connect both of your DVR's satellite input jacks, you
