In many small communication devices both a liq- uid crystal display (LCD) and a keypad are used by the consumer to direct software menu options such as set- ting the time of day, an alarm, various audible tones or scrolling through a message on the LCD screen. It is not very clear how to do any of these functions without carefully reading a detailed instruction manual, which generally leads to customer frustration and discontent with the product. Currently, to help the customer adapt to the software menu, blinking icons are used to indi- cate which menu is active, however, this doesn't clearly show the necessary keypad buttons that can be used to open or change this menu.
