What is the learning code and how do I use it?

The learning code is 9-9-9-0-0 for learning new commands and 9-9-9-1-0 for clearing learned codes. After pressing and holding the device selection button for 5 seconds until the red LED is on, enter the appropriate learning code to activate either learning or clearing mode.
