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 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.
Notice:
(1) A Unshielded-type power cord is required in order to meet FCC emission limits and also to prevent
interference to the nearby radio and television reception. It is essential that only the supplied
power cord by used.
(2) Use only shielded cables to connect I/O devices to this equipment.
(3) Changes or modifications not expressly approved by the party responsible for compliance could

FCC RF Radiation Exposure Statement
This Wireless LAN radio device has been evaluated under FCC Bulletin OET 65 and found compliant
to the requirements as set forth in CFR 47 Sections 2.1091, 2.1093, and 15.247 (b) (4) addressing RF
Exposure from radio frequency devices. The radiated output power of this Wireless LAN device is far
below the FCC radio frequency exposure limits. Nevertheless, this device shall be used in such a
manner that the potential for human contact during normal operation is minimized. When nearby
persons has to be kept to ensure RF exposure compliance, in order to comply with RF exposure limits
established in the ANSI C95.1 standards, the distance between the antennas and the user should not
be less than 20 cm.

1. Getting Started
1.1 Safety Precautions
Warning!
Always completely disconnect the power cord from your
chassis whenever you work with the hardware. Do not
make connections while the power is on. Sensitive
electronic components can be damaged by sudden power
surges. Only experienced electronics personnel should
open the PC chassis.
Caution!
Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution,
use a grounding wrist strap at all times. Place all electronic
components in a static-dissipative surface or static-shielded
bag when they are not in the chassis.
