4. Industry Canada Statement
This device complies with Industry Canada licence‐exempt RSS standards. Operation is subject to the following
two conditions:
1. This device may not cause interference.
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.
This device complies with the safety requirements for RF exposure in accordance with RSS-102 Issue 5 for
portable use conditions.
This radio transmitter (IC : 9653A‐CPM01) has been approved by Industry Canada to operate with the antenna
types listed below with the maximum permissible gain 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.

5. Conformité IC
Le présent appareil est conforme aux CNR dʹIndustrie Canada applicables aux appareils radio exempts de
licence. Lʹexploitation est autorisée aux deux conditions suivantes :
1. Lʹappareil ne doit pas produire de brouillage.
2. Lʹutilisateur de lʹappareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est
susceptible dʹen compromettre le fonctionnement.
Conformément à la réglementation dʹIndustrie Canada, le présent émetteur radio peut fonctionner avec une
antenne dʹun type et dʹun gain maximal (ou inférieur) approuvé pour lʹémetteur par Industrie Canada. Dans le
but de réduire les risques de brouillage radioélectrique à lʹintention des autres utilisateurs, il faut choisir le type
dʹantenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas
lʹintensité nécessaire à lʹétablissement dʹune communication satisfaisante.
Cet appareil est conforme avec les exigences de sécurité pour l’exposition aux radiofréquences conformément
au CNR-102, 5e édition, pour les conditions d’utilisation portables.
Le présent émetteur radio (IC : 9653A‐CPM01) a été approuvé par Industrie Canada pour fonctionner avec les
types dʹantenne énumérés ci‐dessous et ayant un gain admissible maximal indiqué *. Les types dʹantenne non
inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour
lʹexploitation de lʹémetteur.
* (et l'impédance d'antenne requise pour chaque type indiqué d'antenne)
