Figure 9-25. This alarm panel has a modal UI. In its default state, the numeric keypad is used to set/unset the alarm with codes. When the menu button is pressed, the numeric keys correspond to different items in nested menus (corresponding to functions such as setting zones, adding/removing users, viewing the system log and changing configuration settings). There are no cues on the device itself as to which number corresponds to which function, or which menus are available, so the user has to cycle through buttons to find the option they want. Labeled buttons would have made functions easier to find, but would have added many more buttons and increased the bill of materials.
