How do I configure certain buttons to always control certain devices?
A feature called Punchthrough lets you set up how various keys on the remote operate in various modes. For example you might want the Volume Up/Down and Mute keys to ALWAYS operate your TV, no matter what mode the remote is in. Or you might want the Play, Stop, Pause REW, FF, and Record keys to ALWAYS operate your DVR no matter what mode the remote is in. Press the HOME key, then select Setup, then select Advanced, then Punchthrough. Then select the device you want to set up Punchthrough for. E.G., TV.
You can configure Volume Up/Down, Mute, Channel Up/Down, and Play, Stop, Pause REW, FF, and Record for punchthrough. If you want some other keys to operate in a different mode from what they normally operate in, you can “learn” the key(s). E.G. if you want you TV’s INPUT key to still switch the TV’s input when you’re in cable mode, you can learn your TV’s INPUT key under cable mode.
