Yes, I've changed a channel on the MCD remote. The best thing I did was to change the operation of the door shade. Originally, hitting the ALL NIGHT + UP button raised all the shades in the coach and hitting the ALL NIGHT + Down button lowered all the coach shades.
Since we often walk the dogs just after sunset we would hit the PASS Window + up button to raise the shade on the door to get out to walk the dogs. That also raised the Pass window shade.
I kept the programming so the door shade would raise along with the window shade when I hit the ALL NIGHT + UP button, but not
come down when I hit the ALL NIGHT + DOWN button.
When we return to the coach, I just hit the PASS WINDOW + DOWN to lower the door shade. This is also nice when we have company. This may not be a preference for many folks, but it works for us.
Anyway, I went on the MCD web page and downloaded their manual for the shades and controller. In that document there are instructions for pairing the shades to the remote.
