FCC 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

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(15.407)
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 below.
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 betweenthe 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 transmitterexcept 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: Metal antenna (Internal Antenna)
-Max. peak Antenna gain
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 informationEnd 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: BEJ-WL1SB21”
“Contains IC: 2703H-WL1SB21 ”
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.

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 device may not cause interference, and
(2) this device must accept any interference, including interference that may cause
undesiredoperation 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
lebrouillage 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.
Caution: Any changes or modifications to this device not explicitly approved by manufacturer
could void your authority to operate this equipment. Attention: Les changements ou modifications
de cet appareil non expressément approuvé par le fabricant peuvent annuler votre droit à utiliser
cet équipement.
Étiquetage du produit final (IC) Le module WL1NB6V2 est étiqueté avec sa propre
identification ISED et son propre numéro de certification IC. Si l’identification ISED 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 IC : 2703H-WL1SB21 »
“The 5155-5245 MHz band is restricted to indoor use only.”
