FCC Radio Frequency Interference Statement
SkyExtender DualBand FCC Number: RV7-DBE1010
This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 90
of the FCC Rules. These limits are designed to provide reasonable protection against 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 and correct the interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the distance between the equipment and the receiver.
•Connect the equipment to 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 equipment has been certified to comply with the limits for a class B computing device, pursuant to FCC Rules.
In order to maintain compliance with FCC regulations, shielded cables must be used with this equipment. Operation
with non-approved equipment or unshielded cables is likely to result in interference to radio and TV reception. The
user is cautioned that changes and modifications made to the equipment without the approval of manufacturer could
void the user's authority to operate this equipment.
Maximum Permissible Exposure
In order to meet Industry Canada, FCC and other regulatory requirements for RF Exposure, the SkyGateway and
SkyExtender units must be located a minimum of 21 cm (8 inches) from all persons. This distance is determined
based upon the aforementioned 1 mW/cm2 limit, measured data, and the following far-field peak power density
equation:

where: d= MPE distance in cm
P= Power in dBm (peak)
G= Antenna Gain in dBi
S= Power Density Limit in mW/cm2(1 mW/cm2)
Certified laboratory measurements indicate that the FCC’s Power Density Limit of 1 mW/cm2 is met at a distance of
much less than 20 cm (8 inches). However the minimum distance for fixed or mobile transmitters is 20 cm even if
calculations indicate the MPE distance is much less.
FCC 15.203 statement
Because this device uses standard RF connectors for the external removable antennas, professional installation is
required.
IC RSS-210 statement
This device has been designed to operate with the external antennas for the 2.4 GHz band listed below, and having a
maximum gain of 7.4 dBi. Antennas not included in this list or having a gain greater than 7.4 dBi are strictly
prohibited for use with this device. The required antenna impedance is 50 ohms.
