Precautions
❑
Provide adequate air circulation to prevent internal overheating. Do not place your computer on porous surfaces such as
rugs, blankets, couches, or beds, or near materials such as curtains or draperies that may block its air vents.
❑
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
VAIO-Link.
❑
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.
