Clearly I made a mistake and duplicated one of the codes. But comparing your first code (Speaker Preset Toggle - 891) to mine, the only difference is the last byte (D vs. E).
Here is the line from the manual:
RCKSK0410891 1101111011**********
Speaker Preset (Toggle)And here is how I entered it in the Pronto Hex Generator:
[Link: ibb.co]As you can see, it's generating the exact same code with an "E" in the last byte.
Did I miss something? Is the Pronto Hex Generator not working? I appreciate everyone's help.
