configured for communication with the Internet. Your computer must be able to connect
to the Internet via the modem, and must have a Web browser installed.

POSITIONING YOUR ROUTER
When positioning your Router, ensure:
• The unit is centrally located to the wireless computers that will connect to the Router. A
suitable location might be on top of a high shelf or similar furniture to optimize wireless
connections to computers in both horizontal and vertical directions, allowing coverage
throughout.
• In order to meet FCC radiation exposure regulations the Router should be located in a
position that maintains a minimum distance of 20 cm (8 inches) from any personnel
(refer to the User Guide for details).
• It is out of direct sunlight and away from sources of heat.
• Cabling is away from power lines, fluorescent lighting fixtures, and sources of electrical
noise such as radios, transmitters and broadband amplifiers.
• Water or moisture cannot enter the case of the unit.
• Air flow around the unit and through the vents in the side of the case is not restricted.
We recommend you provide a minimum of 25 mm (1 in.) clearance.
