•
A wireless LAN card is not meant for use with facilities or equipment involving the safeguard
of human life, such as medical equipment, nuclear facilities or equipment, aeronautical or

requiring high levels of reliability. Do not use the card in such cases.
•
Do not use a wireless LAN card near cardiac pacemakers.
•
Do not use a wireless LAN card near medical equipment. Doing so may cause electromagnetic
interference with the medical equipment, possible leading to death.
•
Do not disassemble or modify a wireless LAN card in any way. Doing so could lead to fire or
electric shock.
•
Do not use a wireless LAN card in wet or moist places, such as in bathrooms or near

•
Static electricity from the human body may damage a wireless LAN card. Before touching
the card, touch an aluminum window frame, a door knob, or some other metal object around
you to eliminate the static electricity.
The radio waves used by a wireless LAN card pass through the wood or glass used in normal
homes (but not through window panes with built-in metallic mesh).
The radio waves do not pass through iron reinforcing bars, metal or concrete, so a wireless LAN
card cannot be used for communicating through walls or floors made with these materials.
