INTRODUCTION
1.1 Overview
LCB-003 is a small size and low power module for Bluetooth with PCB antenna. LCB-003 use the
nRF52810 solution(Nordic), and it can be applied to air solution etc.
Nordic nRF52810 is a highly integrated single-chip low power Bluetooth network controller. It
combines an ARM-Cortex M4 MCU, Bluetooth, and RF in a single chip. It also provides a bunch of
configurableGPIOs which are configuredas digital peripherals for different applications and control
usage.
nRF52810 integrates internal memoriesfor complete Bluetooth functions. The embeddedmemory
configurationalso provides simple application developments.

FCCCERTIFICATION
5.1 FCC Notice
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 the receiver.
-
Connect the equipment to 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.
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 of the device.
Any changes or modifications in construction of this device which are not expressly
approved by the party responsible for compliance could void the user’s authority to
operate the equipment.

ICCERTIFICATION
6.1 Industry Canada Statement
This device contains licence-exempt transmitter(s)/receiver(s) that comply with Innovation,
Science and Economic Development Canada’s licence-exempt RSS(s). Operation is subject
to the following two conditions:
(1)
This device may not cause interference.
(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.
Please notice that if the IC identification number is 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. This exterior label can use wording such
as the following: “Contains IC : 2703N-LCB003” any similar wording that expresses
the same meaning may be used.
L’étiquette d’homologation d’un module d’Innovation, Sciences et Développement
économique Canada devra être posée sur le produit hôte à un endroit bien en vue, en tout
temps. En l’absence d’étiquette, le produit hôte doit porter une étiquette sur laquelle figure le
numéro d’homologation du module d’Innovation, Sciences et Développement économique
Canada, précédé du mot « contient », ou d’une formulation similaire allant dans le même sens
et qui va comme suit : Contient IC : 2703N-LCB003 est le numéro d’homologation du mo

9. Module Integration Guide
1. Applicable FCC Rules
a. CFR 47 Part 15.247
2. Operational Condition
The module is limited to OEM installation ONLY. The OEM integrator is responsible for
ensuring that the end-user has no manual instruction to remove or install module. A
separate approval is required for all other operating configurations, including portable
configurations with respect to Part 2.1093, Part 15 Subpart B, and difference antenna
configurations.
3. Limited Module Procedure: N/A
4. Trace antenna designs: N/A
5. RF Exposure consideration
This modular complies FCC/ISED RF exposure requirement at 15 mm distance. Any host
equipment that has separation distance less than 15 mm shall require additional RF
exposure assessment.
6. Antennas
This modular has PCB pattern antenna.
Any changes of antenna designs might require additional assessment.
Antenna type shall be same type and antenna gain shall be less or equal to certified
antenna.
7. Label and compliance information
The end user manual shall include all required regulatory information/warning as shown
in this manual. If the FCC identification number is 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.
This exterior label can use wording such as the following:
“Contains FCC ID : BEJ-LCB003” any similar wording that expresses the same meaning
may be used.
8. Information on test modes and additional testing requirements
This modular was tested in standalone configuration. Integration of this modular into a
host equipment would require additional testing.

9. Module Integration Guide
9. Additional testing, Part 15 Subpart B disclaimer
The grantee should include a statement that the modular transmitter is only FCC authorized for the
specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product
manufacturer is responsible for compliance to any other FCC rules that apply to the host not
covered by the modular transmitter grant of certification. If the grantee markets their product as
being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity),
then the grantee shall provide a notice stating that the final host product still requires Part 15
Subpart B compliance testing with the modular transmitter installed.
