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.
Operations in the 5.15-5.25GHz band are restricted to indoor usage only
IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to channels 1
through 11.
21
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and
2) The transmitter module may not be co-located with any other transmitter or antenna,
3) 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: RRK-WMPND02A1”.
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
22
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 3.21dBi. 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.
Caution:
The device for the band 5150-5250 MHz is only for indoor usage to reduce potential for harmful
interference to co-channel mobile satellite systems.
Because high power radars are allocated as primary users (meaning they have priority) in 5250-5350
MHz and 5650-5850 MHz, these radars could cause interference and/or damage to license exempt LAN
devices.
IMPORTANT NOTE:
IC Radiation Exposure Statement:
This equipment complies with IC 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.
