User's Manual

4
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.
Export restrictions
This product or software contains encryption code which may not
be exported or transferred from the US or Canada without an
approved US Department of Commerce export license.
FCC Guidelines for Human Exposure
CAUTION: To comply with FCC RF exposure
compliance, a separation distance of at least 20
cm (8 inches) must be maintained between the
antenna of this device and all persons
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 including
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.
