Notes on Use This section describes safety guidelines and precautions to help protect your computer from potential damage. On Handling the LCD Screen u Do not leave the LCD facing the sun as it can damage the LCD. Be careful when using the computer near a window. u Do not scratch the LCD or exert pressure on it. This could cause malfunction. u Using the computer in low temperature conditions may produce a residual image on the screen. This is not a malfunction. When the computer returns to normal temperature, the screen returns to normal. u A residual image may appear on the screen if the same image is displayed for a lengthy period of time. The residual image disappears in a while. You can use a screen saver to prevent residual images. u The screen becomes warm during operation. This is normal and does not indicate a malfunction. u The LCD is manufactured using high-precision technology. You may, however, see tiny black points and/or bright points (red, blue, or green) that continuously appear on the LCD. This is a normal result of the manufacturing process and does not indicate a malfunction. On the Power Source u Your computer operates on 100V-240V AC 50/60 Hz. u Do not share the AC outlet with other power-consuming equipment, such as a copy machine or shredder. u You can purchase a power strip with a surge protector. This device prevents damage to your computer caused by sudden power surges such as those that may occur during an electrical storm. u Do not place heavy objects on the power cord. 71
