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, under part 15 of the FCC Rules. These limits are designed to protect reasonably against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used per the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. Suppose this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on. In that case, 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.
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)
LG Electronics USA 111 Sylvan Avenue North Building, Englewood Cliffs, New Jersey, United States
Regulatory Statement (FCC)
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 that are the same type and have equal or less gain than 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 by 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 Pattern Antenna
- Max. peak Antenna gain
- Ant: 0.95 dBi (2405 – 2480 MHz)
Any new antenna type, with a higher gain than the listed antenna should be the requirements of FCC rules 15.203 and 2.1043 as procedure.
Label and compliance information
End Product Labeling
The module is labeled with sown FCC ID and IC certification number. If the FCC ID and IC CertificationNumberarenotvisiblewhen 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 be labeled in the visible following:
- Contains FCC ID: BEJ-MTMB01
- Contains IC: 2703N-MTMB01
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

Regulatory Statement (ISED)
RSS-GEN, Sec. 7.1.3–(licence-exempt radio apparatus)
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions:
- this device may not cause interference, and
- this device must accept any interference, including interference that may cause undesired operation of the device.
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.
