I Had The Same Problem with the same receiver...I discovered that the remote CKE67G1 Is the correct remote for RV-9935A but I still couldn't find the manual for it. I did find was a manual for RV-9900 and that model used the same remote so the instructions on programming the remote in that users manual are the correct instructions for the RV-9935a.You can download it from here: [Link: retrevo.com]
