6. FCC, ISED Statement

FCC Part 15.19

This device complies with part 15 of the FCC Rules.

Operation is subject to the following two conditions: (1) This device may not cause harmful interference,

and (2) this device must accept any interference received, including interference that may cause undesired operation.

FCC Part 15.21

Any changes or modifications (including the antennas) to this device that are not expressly approved

by the manufacturer may void the user's authority to operate the equipment.

Please notice that if the FCC identification 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 FCC ID:BEJ-PWFSA3” any similar wording that expresses the same meaning may be used.

Manual Information to the End User

The module is limited to OEM installation ONLY.

The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module.

The module is limited to installation in fixed application;

A separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and difference antenna configurations.

There is requirement that the grantee provide guidance to the host manufacturer for compliance with Part 15B requirements.

FCC RF Radiation Exposure Statement: This equipment complies with FCC RF Radiation exposure limits set forth for an uncontrolled environment.

This device and its antenna 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 cm between the radiator and your body.

Please notice that if the IC identification 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:2703N-PWFSA3” any similar wording that expresses the same meaning may be used.

L’étiquette d’homologation d’un module d’Innovation, Sciences et Développement économique Canada devra être posée sur le produit hôte à un endroit bien en vue, en tout temps.

En l’absence d’étiquette, le produit hôte doit porter une étiquette sur laquelle figure le numéro d’homologation du module d’Innovation, Sciences et Développement économique Canada,

précédé du mot « contient », ou d’une formulation similaire allant dans le même sens et qui va comme suit :

Contient IC : 2703N-PWFSA3 est le numéro d’homologation du module

Intergration instruction

The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this

module. The end user manual shall include all required regulatory information/warning as shown in this manual.

For mobile and fixed operation configurations the antenna gain, including cable loss will be registered under the following identifiers:

FCC Identifier: BEJ-PWFSA3
