the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interferenc e
to radio or television reception, which can be determined by turning th e equi pment off and on, the user is enco uraged to
try to correct the interference by one of the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and receiver.

- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to the follo wing two conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interferenc e
that may cause undesired operation.

FCC Caution: Any changes or modifications not expressly approved b y the party responsible for compliance could voi d
the user's authority to operate this equipment.

IMPORTANT NOTE:
FCC Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled enviro nment. This equipment
should be installed and operated with minimum distance 20cm between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

2 Installation

2.1 Hardware Installation

Step 1: Place the Wireless LAN Broadband Router to the best optimum transmission

location. The best transmission location for your WLAN Broadband Router is
usually at the geographic center of your wireless network, with line of sign to all
of your mobile stations.

Step 2: Connect the WLAN Broadband Router to your wired network. Connect the

Ethernet WAN interface of WLAN Broadband Router by category 5 Ethernet
cable to your switch/ hub/ xDSL modem or cable modem. A straight-through
Ethernet cable with appropriate cable length is needed.

Step 3: Supply DC power to the WLAN Broadband Router. Use only the AC/DC power

adapter supplied with the WLAN Broadband Router; it may occur damage by
using a different type of power adapter.

The hardware installation finished.

2.2 Software Installation

¾ There are no software drivers, patches or utilities installation needed, but only the

configuration setting. Please refer to chapter 3 for software configuration.

Notice: It will take about 55 seconds to complete the boot up sequence after

powered on the WLAN Broadband Router; Power LED will be active,
and after that the WLAN Activity LED will be flashing to show the
WLAN interface is enabled and working now.
