Wireless Dual-band Network Adapter

Introduction

The Wireless Dual-band Network Adapter (WN8122E-HF-19) is another
cutting edge introduction in both 5GHz and 2.4GHz wireless
communication for digital TV, desktop and notebook computers.
Designed for both home entertainment and SOHO environments, this
system-embedded wireless network adapter provides the high speed,
stable coverage and secure security expected by today’s wireless users.
WN8122E-HF-19 is IEEE 802.11n compliant while maintaining full
backwards compatibility with the 802.11a, 802.11b and 802.11g
standards. It utilizes advanced MIMO (Multiple-In, Multiple-Out)
technology to deliver incredible speed and range. The Wireless Dual­band Network Adapter provides better performance than existing

802.11g technology. Upgrading to wireless 11n network provides an
excellent solution for sharing an Internet connection and files such as
video, music, photos, and documents.

Federal Communication Commission Interference Statement

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 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 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 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 harmful interference, and (2) this device must accept
any interference received, including interference that may cause undesired operation.

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

For operation within 5.15 ~ 5.25GHz frequency range, it is restricted to indoor use only.
