FCC Statement

FCC Part 15.19 Statements:| This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

this device may not cause harmful interference,
this device must accept any interference received, including interference that may cause undesired operation.

---|---
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, under 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 by 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 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.

FCC 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.

Modular Approval Statement| Regulatory notice to host manufacturer according to KDB 996369 D03 OEM Manual

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 that are the same type and have equal or less gain than an antenna listed below this instruction manual.

RF exposure considerations

-The module has been certified for integration into products only by OEM integrators under the following conditions:

-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 under 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.

-. Max. Antenna gain: 3.52 dBi / Ant. Type: FPC Antenna

Any new antenna type, with a higher gain than the listed antenna should meet the requirements of FCC rules 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 end product must be labeled in a visible area with the following:

“Contains FCC ID: BEJ-LCWB005EA “Contains IC: 2703N-LCWB005EA

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.

ISED Statement
