Canadian Notice

This device complies with ISED (formerly Industry Canada) license-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.

User's Manual 1-5

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'appareil doit accepter tout brouillage radioélectrique subi, même si

le brouillage est susceptible d'en compromettre le fonctionnement.

To comply with the Canadian RF exposure compliance requirements,

this device and its antenna must not be co-located or operating in

conjunction with any other antenna or transmitter.

Pour être conforme aux exigences canadiennes en matière

d'exposition aux fréquences radio, l'appareil et son antenne ne doivent

pas être situés au même endroit qu'une autre antenne ou un autre

émetteur ni fonctionner en même temps.

This device is restricted to indoor use due to its operation in the 5.15

GHz to 5.25 GHz frequency range. FCC requires this product to be

used indoors for frequency range 5.15 GHz to 5.25 GHz to reduce the

potential for harmful interference to co-channel Mobile Satellite

systems.

High power radars are allocated as primary users of the 5.25 GHz to

5.35 GHz and 5.65 GHz to 5.85 GHz bands. These radar stations can

cause interference with and/or damage this device.

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.

Veuillez noter que les utilisateurs de radars de haute puissance sont

désignés utilisateurs principaux (c.-à-d., qu’ils ont la priorité) pour les

bandes 5250-5350 MHz et 5650-5850 MHz et que ces radars

pourraient causer du brouillage et/ou des dommages aux dispositifs

LAN-EL.

The above caution applies to products that operate with an 802.11a/n/ac/ax

radio device.

La mise en garde ci-dessus ne s’applique qu’aux appareils ayant un

transmetteur opérant en mode 802.11a/n/ac/ax.
