FCC Information to User

This product does not contain any user serviceable

components and is to be used with approved antennas only.

Any product changes or modiï¬cations will invalidate all

applicable regulatory certiï¬cations and approvals.

FCC Electronic Emission Notices

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

2. This device must accept any interference received,

including interference that may cause undesired

operation.

FCC Radio Frequency Interference statement

The wireless LAN card is subject to the rules of the Federal

Communications Commission (FCC). This card is

considered an intentional radiator as per the FCC guidelines.

NOTE: This equipment has been tested and found to

comply with the limits for 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 instruction manual, 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 or more of the following measures:

â¢ Reorient or relocate the receiving antenna.

â¢ Increase the separation between the equipment and

receiver.

â¢ Connect the equipment into an outlet on a circuit different

from that to which the receiver is connected.

â¢ Consult the dealer or an experienced radio/TV technician

for help.

WARNING Any changes or modiï¬cations of equipment not

expressly approved by Intersil could void the userâs authority

to operate the equipment.

FCC Guidelines for Human Exposure

The EIRP was measured for the lower, middle and highest

frequencies used by the transmitter. The results in Table 5

are based on a safe distance between antenna and

operator of eight inches.The equipment therefore fulï¬lls the

requirements on power density for general population /

uncontrolled exposure of 1.0mW/cm2 and therefore

complies with the requirements of FCC part 15.247 (b) (4)

and FCC OET Bulletin 65 including supplements A, B and C.

CAUTION: This assembly is designed to operate with a

supply voltage of 3.3V in laptop computers supporting the

miniPCI standard.

CAUTION: Do not force engagement of the card in the

miniPCI slot. It is mechanically designed to prevent improper

insertion.

Permanent damage may occur if operated outside of the

speciï¬ed operating limits listed in this document.
