Warning
4.5.1 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 1.7cm 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:
1) The antenna must be installed such that 1.5 cm is maintained between the antenna and users, and
2) The transmitter module may not be co-located with any other transmitter or antenna.
RTL8188EE
mini-Card User Manual
10 Rev.1.0
As long as 2 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 1.7
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: TX2-RTL8188EE”.
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.
4.5.2 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
French translation:
Ce dispositif est conforme à la norme CNR-210 d'Industrie Canada applicable aux appareils radio exempts
de licence. Son fonctionnement est sujet aux deux conditions suivantes: (1) le dispositif ne doit pas produire
de brouillage préjudiciable, et (2) ce dispositif doit accepter tout brouillage reçu, y compris un brouillage
susceptible de provoquer un fonctionnement indésirable.
This device has been designed to operate with an antenna having a maximum gain of 3.45dBi.
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.
French translation:
Ce dispositif a été conçu pour fonctionner avec une antenne ayant un gain maximum de 3.45 dBi. Une antenne
RTL8188EE
mini-Card User Manual
11 Rev.1.0
à gain plus élevé est strictement interdite par les règlements d'Industrie Canada. L'impédance d'antenne
requise est de 50 ohms.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peutfonctionner avec une
antenne d'un type et d'un gain maximal (ou inférieur) approuvé pourl'émetteur par Industrie Canada. Dans le
but de réduire les risques de brouillage radioélectriqueà l'intention des autres utilisateurs, il faut choisir le
type d'antenne et son gain de sorte que lapuissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas
l'intensité nécessaire àl'établissement d'une communication satisfaisante.
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 1.7cm between the radiator & your
body.
French translation:
NOTE IMPORTANTE: (Pour l'utilisation de dispositifs mobiles)
Déclaration d'exposition aux radiations:
Cet équipement est conforme aux limites d'exposition aux rayonnements IC établies pour un environnement
non contrôlé. Cet équipement doit être installé et utilisé avec un minimum de 1.7 cm de distance entre la
source de rayonnement et votre corps.
This device is intended only for OEM integrators under the following conditions:
1) The antenna must be installed such that 1.7 cm is maintained between the antenna and users, and
2) The transmitter module may not be co-located with any other transmitter or antenna,
As long as 2 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.
French translation :
Cet appareil est conçu uniquement pour les intégrateurs OEM dans les conditions suivantes: (Pour
utilisation de dispositif module)
1) L'antenne doit être installée de telle sorte qu'une distance de 1.5 cm est respectée entre l'antenne et les
utilisateurs, et
2) Le module émetteur peut ne pas être coïmplanté avec un autre émetteur ou antenne
Tant que les 2 conditions ci-dessus sont remplies, des essais supplémentaires sur l'émetteur ne seront pas
nécessaires. Toutefois, l'intégrateur OEM est toujours responsable des essais sur son produit final pour
toutes exigences de conformité supplémentaires requis pour ce module installé.

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 IC authorization is no longer considered
valid and the IC 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 IC
authorization.
French translation:
NOTE IMPORTANTE:
Dans le cas où ces conditions ne peuvent être satisfaites (par exemple pour certaines configurations
d'ordinateur portable ou de certaines co-localisation avec un autre émetteur), l'autorisation du Canada n'est
plus considéré comme valide et l'ID IC ne peut pas être utilisé sur le produit final. Dans ces circonstances,
l'intégrateur OEM sera chargé de réévaluer le produit final (y compris l'émetteur) et l'obtention d'une
autorisation distincte au Canada.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be installed such that 1.7
