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