Federal Communication Commission Interference Statement
This equipment has been tested and found to comply with the limits for a 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 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 to correct the interference by one 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.
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, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate this equipment.
IMPORTANT NOTE:
FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to channels
1 through 11.
This device is intended only for OEM integrators under the following conditions:
The antenna must be installed such that 20 cm is maintained between the antenna and users,
and
The transmitter module may not be co-located with any other transmitter or antenna,
For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for
2.4G band by supplied firmware programming tool. OEM shall not supply any tool or info to the
end-user regarding to Regulatory Domain change.
As long as 3 conditions above are met, further transmitter test will not be required. However,
the OEM integrator is still responsible for testing their end-product for any additional
compliance requirements required with this module installed (for example, digital device
emissions, PC peripheral requirements, etc.).
IMPORTANT NOTE: In the event that these conditions can not be met (for example certain
laptop configurations or co-location with another transmitter), then the FCC authorization is no
longer considered valid and the FCC ID can not be used on the final product. In these
circumstances, the OEM integrator will be responsible for re-evaluating the end product
(including the transmitter) and obtaining a separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be
installed such that 20 cm may be maintained between the antenna and users. The final end
product must be labeled in a visible area with the following: “Contains FCC ID:
RRK2005100093”.
Manual Information To the End User
The OEM integrator has to be aware not to provide information to the end user regarding how
to install or remove this RF module in the user’s manual of the end product which integrates
this module.
The end user manual shall include all required regulatory information/warning as show in this
manual.
Industry Canada Statement
This device complies with RSS-210 of the Industry Canada Rules. Operation is subject to the
following two conditions:
1) this device may not cause interference and
2) this device must accept any interference, including interference that may cause undesired
operation of the device
This device has been designed to operate with an antenna having a maximum gain of 4.74
dBi.
Antenna having a higher gain is strictly prohibited per regulations of Industry Canada. The
required antenna
impedance is 50 ohms.
To reduce potential radio interference to other users, the antenna type and its gain should be
so chosen that the EIRP is not more than required for successful communication.
IMPORTANT NOTE:
IC Radiation Exposure Statement:
This equipment complies with IC radiation exposure limits set forth for an uncontrolled
environment. End users must follow the specific operating instructions for satisfying RF
exposure compliance. To maintain compliance with IC RF exposure compliance requirements,
please follow operation instruction as documented in this manual.
