Preventing Computer Virus Infections Computer virus is a malicious program that negatively affects PC's operations, and the infection can occur through the Internet and emails. Once infected, it not only destroys programs and data on infected PCs, but it could also infect other PCs as well. Some models include software that prevents computer virus infection and removes them. We recommend performing routine checks. Also in order to address growing number of viruses, you need to update the "Virus Definition File". Preventing Failures and Malfunctions • Cautions when carrying a PC (for notebook PC) When carrying a notebook PC, always hold it by its main body. If you hold the LCD panel side, an excessive amount of power may be sent to the LCD panel, which may cause failure or damage. • Care and Maintenance Clean this product frequently to prevent any failure or malfunction. • Cleaning the Lens Never use commercially available cleaning disk or lens cleaner when cleaning the lens in DVD/CD drive (including Blu-ray disk drive). It may have an opposite effect of collecting dust, and cause a failure or malfunction by staining the lens in DVD/CD drive (including Blu-ray disk drive). • Cleaning the Vents Remove dust accumulated around the vents periodically. Clogging of the vents with dust leads to bad airflow, which may cause this product to fail or malfunction. • Cleaning the Keyboard Do not use a vacuum cleaner to clean the keyboard. The keys may come off. If any dust falls between the keys, use a (nonflammable) air duster intended for precision devices to remove it. Do not attempt to remove the keys. You may not be able to put them back on or damage the keys or keyboard, and cause the product to fail or malfunction. 7
