This section provides a brief description of the main component features. The Mouse The pointing device included in your Aspire computer system is an optical mouse. Unlike a traditional mouse that requires the use of a mouse pad for its ball system to work effectively, an optical mouse can be used on almost any surface. This allows you to operate your mouse anywhere in the vicinity of your computer - an important advantage on a cluttered desktop. Your optical mouse works by continuously bouncing a small beam of light off the surface on which it is being operated. The information from the returning light beams is read by the mouse and transmitted to the computer. In this way, your computer is able to calculate the precise movements of the mouse. Although your mouse can be used effectively on most surfaces, highly reflective materials, such as glass or metal, can distort the light signal. If you wish to operate your mouse on a reflective surface you should first cover the surface with a non-reflective object, such as a book or a sheet of paper. Your mouse features standard controls: two buttons and a scroll wheel for convenient navigation in documents and web pages. Connect the cord to one of the computer's USB ports. 5 The Keyboard Your Aspire computer system features a multimedia keyboard, providing one-touch control for the most important multimedia functions, as well as instant access to your favorite websites. Your keyboard features a standard set of keys, including 12 function keys, four cursor direction keys and a numeric keypad.
