Precautions >
Handling Your Computer
❑ Do not use your computer directly on your lap. The temperature of the base of the unit will rise during normal operation
and over time could result in discomfort or burns.
❑ Your computer uses high-frequency radio signals and may cause interference to radio or TV reception. If this occurs,
relocate the computer a suitable distance away from the set.
❑ Use only specified peripheral equipment and interface cables. Otherwise, problems may occur.
❑ Do not use cut or damaged connection cables.
❑ If your computer is brought directly from a cold location to a warm one, moisture may condense inside the computer. In
this case, allow at least one hour before turning on the computer. If any problems occur, unplug the computer and contact
an authorized Sony Service Center. To find the nearest center or agent, see Finding More about Your VAIO Computer
(page 5) .
❑ Make sure you disconnect the AC adapter and remove the battery pack before cleaning your computer.
❑ To avoid losing data when your computer is damaged, back up your data regularly.
