Once you power up the DirecTV receiver during the boot up process the DirecTV receiver will power cycle a couple of times. To setup up a receiver you need to use the front panel on the receiver not the remote control.
On the first screen you need to highlight and select English.
Next make sure the yellow highlighted box is displaying the Dish Type that you are using for commercial DirecTV headend.
When you find the right dish type move the cursor to the lower right and select Continue.
On the next screen you will see the receiver Verifying configuration.
If everything is hooked up correctly you will see this screen.
Once activated correctly the DirecTV receiver should go to this screen. It is now ready for channel selection.
