You should be able to use the remote's keymover function to assign these functions to keys you don't otherwise use. To do this:

Press the device button you programmed as device 0775

Hold the "setup" or "program" or "magic" button, it's the one you used to set the device button as code 0775. After you hold it a couple of seconds it will blink, like when you programmed the device.

Enter 9 9 4

Press the setup button briefly

Enter the advanced code for the function you want (see below).

Press the button you want to perform the function.
The remote will blink again. The key is now reprogrammed.

If you take too long to perform any of the steps you have to start over.

An advanced code for exit (cancel) is 080. An advanced code for enter (select) is 016. For advanced codes to perform other functions you can see [Link: hifi-remote.com]

I hope this helps.
