A:Answer Yes, and you don't need the Polk remote to do it.
I don't remember how I did it, but remember i did a Google search and found the answer fairly quickly.
If you have Comcast/Xfinity, you can also sync it to their remote. Press the setup button in the lower left of their remote for 5 seconds and you should see the red light at the top of the remote turn green. Type in the 5-digit Polk code and the green light should flash twice. If that doesn't work, try another code. Sadly, I didn't write down the 5-digit code, but you can do another Google search to get the codes: Polk codes for Xfinity remote.
Hope this helps.
