23 * ATI Remote Wonder II Channel Configuration
25 * The remote control can by assigned one of sixteen "channels" in order to facilitate
26 * the use of multiple remote controls within range of each other.
27 * A remote's "channel" may be altered by pressing and holding the "PC" button for
28 * approximately 3 seconds, after which the button will slowly flash the count of the
29 * currently configured "channel", using the numeric keypad enter a number between 1 and
30 * 16 and then press the "PC" button again, the button will slowly flash the count of the
31 * newly configured "channel".
