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.
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 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.
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.
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
COMPANY CONFIDENTIAL
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
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: MCLT77H262”.
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.
Canadian Regulatory Wireless Notice
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.
IMPORTANT NOTE:
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.
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
COMPANY CONFIDENTIAL
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.
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,
3) For all products market in Canada, 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.
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,
3) Pour tous les produits vendus au Canada, OEM doit limiter les fréquences de
fonctionnement CH1 à CH11 pour bandes de fréquences 2.4G grâce aux outils de
microprogrammation fournis. OEM ne doit pas fournir d'outil ou d'informations à
l'utilisateur final en ce qui concerne le changement de réglementation de domaine.
Tant que les 3 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
COMPANY CONFIDENTIAL
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
