Don't lose control! The DIRECTV RC66RX Remote control operates all features of the DIRECTV receiver. It also has an option to operate select DIRECTV receivers that are fitted with standard RF capability. The built-in RF feature allows the DIRECTV remote to control the receiver without having to point it at the receiver, even from another room or in a setup where objects (such as a cabinet door) are likely to block the beam. Requires 2 AA batteries.
