 If you place your AirPort Express behind furniture, keep at least an inch of space
between the AirPort Express and the edge of the furniture.
 Avoid placing your AirPort Express in areas surrounded by metal surfaces on three or
more sides.
 If you place your AirPort Express in an entertainment center with your stereo
equipment, avoid completely surrounding AirPort Express with audio, video, or
power cables. Place your AirPort Express so the cables are to one side. Maintain as
much space as possible between AirPort Express and the cables.
 If you place your AirPort Express behind your stereo equipment, place it on one side
or the other. Avoid centering it behind your stereo.
 Try to place your AirPort Express at least 25 feet from a microwave oven and a 2.4
GHz cordless phone, or other sources of interference.
