General Precautions
PC card overheating
Some PC cards can become hot with prolonged use. Overheating of a PC
card can result in errors or instability in the PC card operation. Also be
careful when you remove a PC card that has been used for a long time.
Mobile phone
Use of mobile phones can interfere with the audio system. Computer
operation is not impaired but is recommended that a distance of 30 cm be
maintained between the computer and a mobile phone in use.
Cooling
1. Cleaning of dust accumulated on the cooling vent of the computer.
When you use your computer in a dusty area, dirt and debris may
accumulate on the cooling vents at the under side of your unit. If this
occurs, the accumulated dust can cause insufficient heat dissipation which
may result in the computer shutting down during use. Carefully clean the
dust from the vents using a vacuum cleaner.
2. Cooling vents on the underside and back side of the computer.
