Provide adequate air circulation to prevent internal heat buildup. Do not 
place your computer on porous surfaces such as rugs or blankets, or near 
materials such as curtains or draperies that may block its ventilation slots. 
Leave a space of at least 8 inches (20 cm) behind the back panel of the 
computer.
If the computer is brought directly from a cold location to a warm one, 
moisture may condense inside your computer. In this case, allow at least 
an hour before turning on your computer. If any problems occur, unplug 
your computer, and contact your Sony Service Center.
The computer uses high-frequency radio signals and may cause 
interference to radio or TV reception. Should this occur, relocate the 
computer a suitable distance away from the set.
Use only specified peripheral equipment and interface cables; otherwise, 
problems may result.
Do not use cut or damaged connection cables.
Your computer will not work with party lines, cannot be connected to a 
coin-operated telephone, and may not work with multiple phone lines or a 
private branch exchange (PBX).
If the telephone company makes a service call to your home or office and 
determines that your computer is responsible for a problem, the telephone 
company may bill you for the service call. Also, if you do not disconnect 
your computer when it is adversely affecting the telephone line, the 
telephone company has the right to disconnect your service until you 
correct the problem.
Handling Your Notebook
Clean the cabinet with a soft, dry cloth or a soft cloth lightly moistened 
with a mild detergent solution. Do not use any type of abrasive pad, 
scouring powder, or solvent such as alcohol or benzine, as these may 
damage the finish of your computer.
Should any solid object or liquid fall into the computer, shut down your 
computer and then unplug it. You may want to have the computer checked 
by qualified personnel before operating it any further.
Do not drop the computer or place heavy objects on top of the computer.
