Once you have learned the commands you want, hit the "OK" button. The IR codes are stored in your interface,
and will function even when MIO Console is not running.
IR Remotes and the Monitor Controller
At this time, the Monitor Controller requires MIO Console to be running to change input or output paths.
However, you can still change the Monitor Controller level while MIO Console is offline.
When using the IR remote, pushing a button once will send the associated command once. If you hold the
button down, the command will repeat after approximately one second. This allows you to change values in
small increments or over a large range.
