Federal Communications Commission (FCC) Statement
15.21
You are cautioned that changes or modifications not expressly approved by the part responsible
for compliance could void the user’s authority to operate the equipment.
15.105(b)
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmfulinterference in a residentialinstallation. 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. Ifthis equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one or more 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
following two conditions:
1) this device may not cause harmfulinterference and
2) this device must accept any interference received, including interference that may cause
undesired operation of the device.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. End users must follow the specific operating instructions for satisfying RF exposure
compliance. This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.

4 Installation
4.1 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 maybe occur damage by using a different type of power adapter.
The hardware installation finished.
