If you already know the IR code you want to use, there's a neat shortcut to enter it during the Setup Wizard.

1. Go through the Audio/Video setup steps as normal
   
2. Make sure you select the correct category and brand of your device
   
3. When you are on the Models screen, select other
   
4. On the list of IR codes, you can actually type in a code in the region that is labelled "current code"

WARNING: the graphical remote which is displayed for your SlingRemote is derived based on a combination of your category/brand/code, so you must have all three right to get the "correct" remote for your particular device.
