The B-Band Converter (BBC) module, installed on your HR20 or H20 receiver, allows you to view the upcoming HD channels. Because DIRECTV's current HD channels do not require the BBC, it may not have been installed.

The easiest way to tell if your H20 or HR20 receiver has the BBC connected to it is to look at the back of the receiver. Look for a module that looks like the one pictured to the right.

If you can't access the back of your receiver and you have an HR20 receiver, tune in to the BBC test channel ? number 499. If you get a message that reads "Searching for signal on Satellite In," you'll be able to enjoy new HD channels from DIRECTV as they become available. If you see the message "Important HD Information. Your B-Band Converter module is NOT connected," you do not have the BBC or it is not connected properly.

The BBC module is easy to install. Follow these simple instructions.

Two BBC modules are required for the HD DVR receiver model HR20. Insert the black, cabled ends of the BBC into the "Satellite In" inputs on the back panel of the receiver. Connect the other ends of the BBC to the cables running from your DIRECTV HD-capable dish.

Connect it as shown: Insert the black, cabled end of the BBC into the "Satellite In" input on the back panel of the receiver. Connect the other end of the BBC to the cable running from your DIRECTV HD-capable dish
