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 EUT is compliance with SAR for general population/uncontrolled exposure
limits in ANSI/IEEE C95.1-1999 and had been tested in accordance with the
measurement methods and procedures specified in OET Bulletin 65 Supplement C.
Operations in the 5.15-5.25GHz band are restricted to indoor usage only.

v1.0
This device is intended only for OEM integrators under the following
conditions:
1) The transmitter module may not be co-located with any other transmitter or
antenna,
2) 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 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
The final end product must be labeled in a visible area with the following: “Contains
FCC ID: ZQ6-AP6234A”.
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.
2006/8/16
v1.0
Industry Canada statement:
This device complies with Industry Canada licence-exempt RSS standard(s). 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.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils
radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes :
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en compromettre le fonctionnement.
(i) the device for operation in the band 5150-5250 MHz is only for indoor use to reduce
the potential for harmful interference to co-channel mobile satellite systems;
(ii) the maximum antenna gain permitted for devices in the bands 5250-5350 MHz and
5470-5725 MHz shall comply with the e.i.r.p. limit; and
(iii) the maximum antenna gain permitted for devices in the band 5725-5825 MHz shall
comply with the e.i.r.p. limits specified for point-to-point and non point-to-point operation
as appropriate.
(iv) Users should also be advised that high-power radars are allocated as primary users
(i.e. priority users) of the bands 5250-5350 MHz and 5650-5850 MHz and that these
radars could cause interference and/or damage to LE-LAN devices.
Avertissement:
(i) les dispositifs fonctionnant dans la bande 5150-5250 MHz sont réservés uniquement pour une
utilisation à l’intérieur afin de réduire les risques de brouillage préjudiciable aux systèmes de
satellites mobiles utilisant les mêmes canaux;
(ii) le gain maximal d’antenne permis pour les dispositifs utilisant les bandes 5 250-5 350 MHz et 5
470-5 725 MHz doit se conformer à la limite de p.i.r.e.;
(iii) le gain maximal d’antenne permis (pour les dispositifs utilisant la bande 5 725-5 825 MHz) doit se
conformer à la limite de p.i.r.e. spécifiée pour l’exploitation point à point et non point à point, selon le
cas.
(iv) De plus, les utilisateurs devraient aussi être avisés que les utilisateurs de radars de haute
puissance sont désignés utilisateurs principaux (c.-à-d., qu’ils ont la priorité) pour les bandes 5 250-5
350 MHz et 5 650-5 850 MHz et que ces radars pourraient causer du brouillage et/ou des dommages
aux dispositifs LAN-EL.

v1.0
Radiation Exposure Statement:
The product comply with the Canada portable RF exposure limit set forth for an uncontrolled
environment and are safe for intended operation as described in this manual. The further RF
exposure reduction can be achieved if the product can be kept as far as possible from the user body
or set the device to lower output power if such function is available.
Déclaration d'exposition aux radiations:
Le produit est conforme aux limites d'exposition pour les appareils portables RF pour les Etats-Unis
et le Canada établies pour un environnement non contrôlé. Le produit est sûr pour un fonctionnement
tel que décrit dans ce manuel. La réduction aux expositions RF peut être augmentée si l'appareil
peut être conservé aussi loin que possible du corps de l'utilisateur ou que le dispositif est réglé sur la
puissance de sortie la plus faible si une telle fonction est disponible.
This device is intended only for OEM integrators under the following conditions:
1) The transmitter module may not be co-located with any other transmitter or antenna.
As long as 1 condition 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:
1) Le module émetteur peut ne pas être coïmplanté avec un autre émetteur ou antenne.
Tant que les 1 condition 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.
