• Part 15.19 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.

• Part 15.105 Statement (Class B)

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 or more 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.

• Part 15.21 Statement

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

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

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

transmitter.

Regulatory Statement (FCC)

Regulatory notice to host manufacturer according to KDB 996369 D03 OEM

Manual v01

List of applicable FCC rules

This module has been granted modular approval as below listed FCC rule parts.

- FCC Rule parts 15C(15.247)

Summarize the specific operational use conditions

The OEM integrator should use equivalent antennas which is the same type and equal

or less gain then an antenna listed in this instruction manual.

RF exposure considerations

The module has been certified for integration into products only by OEM integrators

under the following condition:

-The antenna(s) must be installed such that a minimum separation distance of at least

20 cm is maintained between the radiator (antenna) and all persons at all times.

-The transmitter module must not be co-located or operating in conjunction with any

other antenna or transmitter except in accordance with FCC multi-transmitter product

procedures.

-Mobile use

As long as the three conditions above are met, further transmitter testing will not be

required.

OEM integrators should provide the minimum separation distance to end users in their

end-product manuals.

•Antennas list

This module is certified with the following integrated antenna.

-Type: PCB Trace Antenna

-Max. peak Antenna gain

BT Ant: 2.90 dBi (2402 - 2480 MHz)

Any new antenna type, higher gain than listed antenna should be met the requirements

of FCC rule 15.203 and 2.1043 as permissive change procedure.

•Label and compliance information

End Product Labeling

The module is labeled with its own 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: BE-0%

Contains IC: 2703H-0%

•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.

Regulatory Statement (FCC)

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 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, 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 MB3021 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-MB3021

Contient module émetteur IC : 2703H-MB3021
