IC Warning : 

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.   

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. 

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 

 d'en compromettre le fonctionnement.

 même si le brouillage est susceptible 

tout brouillage radioélectrique subi, 

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.

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. Any 

Changes or modifications not expressly approved by the party responsible for compliance could
