Regulatory Statement (FCC)
• 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.
• Responsible Party Information (Supplier's Declaration of Conformity)

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, E(15.247, 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 in this instruction manual.
RF exposure considerations
The module has been certified for integration into products only by OEM integrators under
the following condition:
Regulatory Statement (FCC)
- 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.
Regulatory Statement (FCC)
Antennas list
This module is certified with the following integrated antenna.
- Type: PCB type
- Max. peak Antenna gain
BT 2400-2485 MHz (1.18 dBi)
WIFI
2400 - 2485MHz ( 1.18 dBi )
5150 - 5500MHz ( 0.74 dBi )
5500 - 5850 MHz ( 1.40 dBi )
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.
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: Label and compliance information
Label and compliance information
•Contains FCC ID: BEJ-LAMWBD1
•Contains IC: 2703N-LAMWBD1
• 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.
Note EMI Considerations
Note that a host manufacture is recommended to use D04 Module Integration Guide
recommending as "best practice" RF design engineering testing and evaluation in case non-
linear interactions generate additional non-compliant limits due to module placement to host
components or properties
For standalone mode, reference the guidance in D04 Module Integration Guide and for
simultaneous mode; see D02 Module Q&A Question 12, which permits the host manufacturer to
confirm compliance.
How to make changes
Since only Grantees are permitted to make permissive changes, when the module will be used
differently than granted, please contact the module manufacture.
Regulatory Statement (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
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 LAMWBD1 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-LAMWBD1
Contient module émetteur IC : 2703N-LAMWBD1
"The 5150-5250 MHz band is restricted to indoor use only"
