Regulation Notice
2. 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 Pattern Antenna
-Max. peak Antenna gain
Frequency Antenna gain
BT LE 2402 ~ 2480 MHz 1.5 dBi
Wi-Fi 2412 ~ 2462 MHz 1.5 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.
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: BEJ-LCWB001
Contains IC: 2703N-LCWB001
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) 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.
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
