Federal Communication Commission Interference Statement

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.

This equipment has been tested and found to comply with the limits for a Class B digital device,

pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable

protection against harmful interference in a residential installation. This equipment generates,

uses and can radiate radio frequency energy and, if not installed and used in accordance with

the instructions, may cause harmful interference to radio communications. However, there is

no guarantee that interference will not occur in a particular installation. If this equipment does

cause harmful interference to radio or television reception, which can be determined by turning

the equipment off and on, the user is encouraged to try to correct the interference by one of the

following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

Consult the dealer or an experienced radio/TV technician for help.

FCC Caution: Any changes or modifications not expressly approved by the party responsible for

compliance could void the user's authority to operate this equipment.

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

transmitter.

This device meets all the other requirements specified in Part 15E, Section 15.407 of the FCC Rules.

Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled

environment. This equipment should be installed and operated with minimum distance 20cm

between the radiator & your body.

This module is intended for OEM integrators only. Per FCC KDB 996369 D03 OEM Manual

v01 guidance, the following conditions must be strictly followed when using this certified

module:

KDB 996369 D03 OEM Manual v01 rule sections:

2.2

List of applicable FCC rules

This module has been tested for compliance to FCC Part 15 Subpart C (15.247) and Subpart E

(15.407).

2.3

Summarize the specific operational use conditions

The module is tested for standalone mobile RF exposure use condition. Any other usage

conditions such as co-location with other transmitter(s) will need a separate reassessment

through a class II permissive change application or new certification.

This module is authorized for Low Power Indoor Client applications only; final host product must

be for indoor operations only.

Further operation restrictions on the host product include:

*Prohibited for control of or Communications with unmanned aircraft systems.

2.4

Limited module procedures

Not applicable.

2.5

Trace antenna designs

Not applicable.

2.6

RF exposure considerations

This equipment complies with FCC mobile radiation exposure limits set forth for an

uncontrolled environment. This equipment should be installed and operated with a minimum

distance of 20cm between the radiator & your body. A separate SAR/Power Density

evaluation is required to confirm compliance with relevant FCC portable RF exposure rules.

This device was tested for typical body-worn operations. To comply with RF exposure

requirements, a minimum separation distance of 5 mm must be maintained between the user’s

body and the handset, including the antenna. Third-party belt-clips, holsters, and similar

accessories used by this device should not contain any metallic components. Body-worn

accessories that do not meet these requirements may not comply with RF exposure

requirements and should be avoided.

Additional testing, Part 15 Subpart B disclaimer

This transmitter module is tested as a subsystem and its certification does not cover the FCC

Part 15 Subpart B (unintentional radiator) rule requirement applicable to the final host. The final

host will still need to be reassessed for compliance to this portion of rule requirements if

applicable.

As long as all conditions above are met, further transmitter test will not be required. However,

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

requirements required with this module installed.

IMPORTANT NOTE: In the event that these conditions can not be met (for example certain

laptop configurations or co-location with another transmitter), then the FCC authorization is no

longer considered valid and the FCC ID can not be used on the final product. In these

circumstances, the OEM integrator will be responsible for re-evaluating the end product

(including the transmitter) and obtaining a separate FCC authorization.

Manual Information To the End User

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 show in this

manual.

OEM/Host manufacturer responsibilities

OEM/Host manufacturers are ultimately responsible for the compliance of the Host and Module.

The final product must be reassessed against all the essential requirements of the FCC rule

such as FCC Part 15 Subpart B before it can be placed on the US market. This includes

reassessing the transmitter module for compliance with the Radio and EMF essential

requirements of the FCC rules. This module must not be incorporated into any other device or

system without retesting for compliance as multi-radio and combined equipment.

Modules: extended to host manufacturers by integration instructions.

This equipment should be installed and operated with greater than 20cm between the radiator & your

body.

Déclaration d'exposition aux radiations:

Cet équipement est conforme aux limites d'exposition aux rayonnements ISED établies pour un

environnement non contrôlé. Cet équipement doit être installé et utilisé à plus de 20 cm entre le

radiateur et votre corps.

This device is intended only for OEM integrators under the following conditions: (For module

device use)

The antenna must be installed and operated with greater than 20cm between the antenna and

users, and

The transmitter module may not be co-located with any other transmitter or antenna.

As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM

integrator is still responsible for testing their end-product for any additional compliance requirements

required with this module installed.

Cet appareil est conçu uniquement pour les intégrateurs OEM dans les conditions suivantes:

(Pour utilisation de dispositif module)

L'antenne doit être installé et exploité avec plus de 20 cm entre l'antenne et les utilisateurs, et

Page 11 of 14

Tant que les 2 conditions ci-dessus sont remplies, des essais supplémentaires sur l'émetteur ne seront

pas nécessaires. Toutefois, l'intégrateur OEM est toujours responsable des essais sur son produit final

pour toutes exigences de conformité supplémentaires requis pour ce module installé.

IMPORTANT NOTE:

In the event that these conditions can not be met (for example certain laptop configurations or co-

location with another transmitter), then the Canada authorization is no longer considered valid and the

IC ID can not be used on the final product. In these circumstances, the OEM integrator will be

responsible for re-evaluating the end product (including the transmitter) and obtaining a separate

Canada authorization.

IMPORTANTENOTE

Dans le cas où ces conditions ne peuvent être satisfaites (par exemple pour certaines configurations

d'ordinateur portable ou de certaines co-localisation avec un autre émetteur), l'autorisation du Canada

n'est plus considéré comme valide et l'ID IC ne peut pas être utilisé sur le produit final. Dans ces

circonstances, l'intégrateur OEM sera chargé de réévaluer le produit final (y compris l'émetteur) et

l'obtention d'une autorisation distincte au Canada.

End Product Labeling

This transmitter module is authorized only for use in device where the antenna may be installed and

operated with greater than 20cm between the antenna and users. The final end product must be labeled

in a visible area with the following: “Contains IC:7542A-MT7922A22M”.

Plaque signalétique du produit final
