Federal Communication Commission Interference Statement
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.
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.
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.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.

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 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.
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
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: QDX31500”. The grantee's
FCC ID can be used only when all FCC compliance requirements are met.
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 harmful interference, and (2) this
device must accept any interference received, including interference that may cause undesired
operation.
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.
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.
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
20 cm de distance entre la source de rayonnement et votre corps.

USER MANUAL
This device is intended only for OEM integrators under the following conditions: (For module
device use)
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.
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.
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 20 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 Canada 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 Canada authorization.
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.
