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