This module has been assessed against the following FCC rule parts: CFR 47 FCC Part 15 C (15.247, 

DTS) and CFR 47 FCC Part 15 E (NII). It is applicable to the modular transmitter. 

 

Canada Statement   

This device complies with Industry Canada’s licence

-exempt RSSs. 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. 

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;

 

(2) 

l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage 

est susceptible d’en compromettre le fonctionnement.

 

 

Please notice that if the ISED certification number is not visible when the module is installed inside 

another device, then the outside of the device into which the module is installed must also display a 

label referring to the enclosed module. This exterior label can use wording such as the following:   

Contains IC: 10256A-

LA02303B” any similar wording that expresses the same meaning may be 

used. l'appareil hôte doit porter une étiquette donnant le numéro de certification du module 

d'Industrie Canada, précédé des mots « Contient un module d'émission », du mot « IC: 10256A-

LA02303B» ou d'une formulation similaire exprimant le même sens, comme suit. 

 

The device meets the exemption from the routine evaluation limits in section 2.5 of RSS 102 and 

compliance with RSS-102 RF exposure, users can obtain Canadian information on RF exposure and 

compliance.   

Le dispositif rencontre l'exemption des limites courantes d'évaluation dans la section 2.5 de RSS 102 

etla conformité à l'exposition de RSS-102 RF, utilisateurs peut obtenir l'information canadienne 

surl'exposition et la conformité de rf.   

 

This transmitter must not be co-located or operating in conjunction with any other antenna or 

transmitter. This equipment should be installed and operated with a minimum distance of 20 

centimeters between the radiator and your body.     

Cet émetteur ne doit pas être Co-placé ou ne fonctionnant en même temps qu'aucune autre antenne 

ouémetteur. Cet équipement devrait être installé et actionné avec une distance minimum de 20 

centimètres
