‐Consult the dealer or an experienced radio/TV technician for help.
For radio equipment operates in 5150-5850MHz
High power radars are allocated as primary users of the 5.25 to 5.35 GHz and 5.65 to 5.85
GHz bands. These radar stations can cause interference with and/or damage to LE LAN
(Licence-Exempt Local Area Network) devices. No configuration controls are provided for
this wireless equipment allowing any change in the frequency of operations outside the
FCC grant of authorization for US operation according to Part 15.407 of the FCC rules.
The device for operation in the band 5150-5250 MHz is only for indoor use to reduce the
potential for harmful interference to co-channel mobile satellite systems; for devices with
detachable antenna(s), the maximum antenna gain permitted for devices in the bands
5250-5350 MHz and 5470-5725 MHz shall be such that the equipment still complies with
the e.i.r.p. limit; for devices with detachable antenna(s), the maximum antenna gain

permitted for devices in the band 5725-5850 MHz shall be such that the equipment still
complies with the e.i.r.p. limits specified for point-to-point and non-point-to-point operation
as appropriate.
Transmitters in the 5.925-7.125 GHz band are prohibited from operating to control or
communicate with unmanned aircraft systems.
Énoncé d’exposition aux rayonnements FCC/IC
L’équipement est conforme aux limites d’exposition aux rayonnements FCC/IC RSS-102
établies pour un environnement non contrôlé. L’équipement doit être installé et utilisé avec
une distance minimale de 20cm entre le radiateur et votre corps.
L’émetteur/récepteur exempt de licence contenu dans le présent appareil est conforme
aux CNR d’Innovation, Sciences et Développement économique 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.
Les radars de puissance élevée sont attribués comme utilisateurs principaux des
fréquences de 5,25 à 5,35 GHz et Bandes de 5,65 à 5,85 GHz. Ces stations radar peuvent
causer des interférences avec Et/ou dommages aux périphériques LE LAN (réseau Local
exempté de licence). Non non Des contrôles de configuration sont fournis pour cet
équipement sans fil permettant toute Modification de la fréquence des opérations en
dehors du FCC octroi d’autorisation Pour les opérations américaines conformément à la
partie 15.407 des règles de la FCC.
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; le gain maximal d’antenne
permis pour les dispositifs utilisant les bandes 5250-5350 MHz et 5470-5725 MHz doit se
conformer à la limite de p.i.r.e.; le gain maximal d’antenne permis (pour les dispositifs
utilisant la bande 5725-5850 MHz) doit se conformer à la limite de p.i.r.e. spécifiée pour
l’exploitation point à point et non point à point, selon le cas.
Il est interdit d’utiliser les émetteurs de la bande de 5,925 à 7,125 GHz pour contrôler les
systèmes d’aéronef sans pilote ou communiquer avec eux.
