FCC CAUTION/ PRUDENCE DE FAC
Any change or modification not approved by the party responsible for compliance could void the user’s authority to operate
this device.
This device requires professional installation.
For operation within 2.4 – 2.4835 and 5.725 - 5.850 GHz frequency ranges, the maximum EIRP must be less than 36 dBm.
The qualified antenna types to be used with this device include:
Low Gain Collinear Omni Antenna (4.5dBi or 6 dBi)
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.
In order to maintain compliance with the FCC RF exposure guidelines, this device should be installed and operated with a
minimum distance of 20cm between the radiator, and the body of the operator and/or nearby persons.
Tout changement ou modification non approuvé par la partie responsable de la conformité pouvait annuler l'autorisation de
l'utilisateur pour l'exploitation de ce dispositif.
Ce dispositif nécessite l'installation professionnelle.
Pour l'opération au sein de la gamme de fréquences de 2.4 – 2.4835 and 5.725-5.850 GHz, la pire maximale doit être
inférieure à 36 dBm. Les types d'antenne qualifiés pour être utilisé avec ce dispositif, citons :
Antenne Omni colinéaires faible Gain colinéaires Omni antenne (4.5dBi ou 6 dBi).
Cet appareil est conforme à la partie 15 des règles de la FCC. Opération est soumis à deux conditions suivantes: (1) ce
dispositif ne peut pas causer de brouillage préjudiciable, et (2) ce dispositif doit accepter toute ingérence a reçu, y compris
le brouillage qui peut provoquer l'opération non désirée.
Afin de maintenir la conformité avec les directives d'exposition RF FCC, ce dispositif doit être installé et exploité avec une
distance minimale de 20 cm entre le radiateur et le corps de l'opérateur ou à proximité de personnes.

IC Notice: IC Avis
1. Under Industry Canada regulations, this radio transmitter may only operate using an antenna
of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To
reduce potential radio interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut
fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour
l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage
radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain
de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité
nécessaire à l'établissement d'une communication satisfaisante.
2. This radio transmitter (IC: 9479A-23MLT and 9479A-58MLT ) has been approved by Industry
Canada to operate with the antenna types listed below with the maximum permissible gain and
required antenna impedance for each antenna type indicated. Antenna types not included in
this list, having a gain greater than the maximum gain indicated for that type, are strictly
prohibited for use with this device.
Le présent émetteur radio (identifier le dispositif par son numéro de certification ou son
numéro de modèle s'il fait partie du matériel de catégorie I) a été approuvé par Industrie
Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un gain
admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne
non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont
strictement interdits pour l'exploitation de l'émetteur.

3. 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.
