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:

  1. This device may not cause harmful interference, and
  2. 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, 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.

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.

<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 below this instruction manual.
Limited module procedures (N/A) Single Module
Trace antenna designs (N/A)
If trace antenna designs are applicable, full-detail design specifications are required per D02 Module Q&A Question 11.
For a modular transmitter with trace antenna designs, see the guidance in Question 11 of KDB Publication 996369 D02 FAQ –Modules for Micro-Strip Antennas and traces. The integration information shall include for the TCB review the integration instructions for the following aspects: layout of trace design, parts list (BOM), antenna, connectors, and isolation requirements.
  • Information that includes permitted variances (e.g., trace boundary limits, thickness, length, width, shape(s), dielectric constant, and impedance as applicable for each type of antenna);
  • Each design shall be considered a different type (e.g., antenna length in multiple(s) of frequency, the wavelength, and antenna shape (traces in phase) can affect antenna gain and must be considered);
  • The parameters shall be provided in a manner permitting host manufacturers to design the printed circuit (PC) board layout;
  • Appropriate parts by manufacturer and specifications;
  • Test procedures for design verification; and
  • Production test procedures for ensuring compliance.

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 40mm 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.
  • portable 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.
  • This module is exclusively for LG Electronics’ finished products.
  • If the host device equipped with this module does not meet the 40mm separation distance requirement, additional certification will be conducted.

* Host device examples: washing machines, air conditioners, refrigerators, ovens, vacuum cleaners, etc.

Antennas
This module is certified with the following integrated antenna.

  • Ant. Type: PCB Pattern Antenna (Max. Antenna gain: 1.67 dBi )
    Any new antenna type, higher gain than listed antennas should be met the requirements of FCC rule 15.203 and 2.1043 as permissive change procedure

Label and compliance information

End Product Labeling (FCC)
The module is labeled with its own FCC ID. If the FCC ID 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. In that case, the final end product must be labeled in a visible area with the following:

* Contains FCC ID: BEJ-LCWB008
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 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.

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 on below contact information.
