PC Card overheating
Some PC Cards can become hot with prolonged use. If two cards are
installed, both can become hot even if only one is used extensively.
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 phones
Use of mobile phones can interfere with the audio system. Computer
operation is not impaired but it is recommended that a distance of 30cm be
maintained between the computer and a mobile phone in use.
