Why does my volume not ramp up/down while keeping pressed?
To lower or raise the volume you need to press multiple times instead of keeping the button pressed like on the original remote.
The reason for this is most likely because the IR code was learned as a single burst IR code rather than a repeated IR code. The cause for this can be because you pressed too short while learning the IR code. Pressing longer will make the control panel recognize the repetition part while learning.
