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.
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 8
inches. The equipment therefore fulfills the requirements on
power density for general population / uncontrolled exposure of
1.0 mW/cm
2
and therefore complies with the requirements of
FCC part 15.247 (b) (4) and FCC OET Bulletin 65 incl.
supplements A, B and C.
WARNING! Any changes or modifications of equipment not expressly approved by
Intersil could void the user’s authority to operate the equipment.
3.3V PC-card Interface Standard
CAUTION: This assembly is designed to operate with a supply
voltage of 3.3V in laptop computers supporting the PC Card
standard.
CAUTION: Do not force engagement of the card in the PC Card
slot. It is mechanically designed to prevent improper insertion.
Permanent damage may occur if operated outside of the specified
operating limits listed in this document.
