15.203 and 2.1043 as permissive change procedure.

7. Regulation Statement

Label and compliance information

•End Product Labeling

The module is labeled with it sown FCC ID and IC Certification Number. If the FCC ID and IC Certification

Number are 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. In that case,

the final end product must be labeled in a visible area with the following:

- Contains FCC ID:BEJ-LAIWB3

- Contains IC:2703N-LAIWB3

•Information on test modes and additional testing requirements

OEM integrator is still responsible for testing their end-product for any additional Compliance

requirements required with this module installed(for example, digital device emissions, PC peripheral

requirements, additional transmitter in the host, etc.).

•Additional testing, Part 15 Subpart B disclaimer

The final host product also requires Part 15 subpart B compliance testing with the modular transmitter

installed to be properly authorized for operation as a Part 15 digital device.

7. Regulation Statement

7.2 ISED

•RSS-GEN, Sec. 7.1.3–(licence-exempt radio apparatus)

This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the

following two conditions:

(1) This devicemay 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 doitpas 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.

•RF Exposure

The antenna (or antennas) must be installed so as to maintain at all times a distance minimum of at least

20 cm between the radiation source (antenna) and any individual. This device may not be installed or

used in conjunction with any other antenna or transmitter.

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.

•É tiquetage du produit final (IC)

Le module LAIWB3 est étiqueté avec sa propre identification FCC et son propre numéro de certification

IC.Si l’identification FCC et le numéro de certification IC ne sont pas visibles lorsque le module est

installé à l’intérieur d’un autre dispositif, la partie externe du dispositif dans lequel le module est installé

devra également présenter une étiquette faisant référence au module inclus. Dans ce cas, le produit

final devra être étiqueté sur une zone visible avec les informations suivantes :

- Contient module émetteur identification FCC ID:BEJ-LAIWB3

- Contient module émetteur IC :2703N-LAIWB3
