Appendix. Regulatory
l'exposition aux RF
L’antenne (ou les antennes) doit être installée de façon à maintenir à tout instant une distance minimum de au moins 20 cm entre la source de
radiation (l’antenne) et toute personne physique.
RSS-GEN, Sec.8.3
This radio transmitter (identify the device by certification number, or model number if Category II) 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.
RSS-GEN, Sec. 8.4
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.
