Information

Integration Instructions
Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01
2.2 List of applicable FCC rules
FCC Part 15.247
2.3 Specific operational use conditions
This transmitter/module and its antenna must not be co-located or operating in conjunction with any transmitter. This information also extends to the host manufacturer’s instruction manual.
2.4 Limited module procedures
Not applicable.
2.5 Trace antenna designs
Not applicable.
2.6 RF exposure considerations
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This compliance to FCC radiation exposure limits for an  uncontrolled environment, and minimum of 5mm separation between antenna and body.
The host product manufacturer would provide the above information to end users in their end-product manuals.
2.7 Antennas
Integral Antenna: 1.15 dBi, 2.4 GHz~2.5 GHz
2.8 Label and compliance information
The end product must carry a physical label or shall use e-labelling followed KDB784748D01 and KDB 784748 stating “Contains Transmitter Module FCC ID: 2ABRU-BLEM203D”.
2.9 Information on test modes and additional testing requirements
For more information on testing, please contact the manufacturer.
2.10 Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) 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. The final host product still requires Part 15 Subpart B  compliance testing with the modular transmitter installed when contains digital circuitry.

FCC Statement

Integrator is reminded to assure that these installation instructions will not be made available to the end user of the final host device.
The final host device, into which this RF Module is integrated has to be labelled with an auxiliary label stating the FCC ID of the RF Module, such as “Contains FCC ID: 2ABRU-BLEM203D”.
“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.”

NOTE: 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.

Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
(OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module.
For 15 B (§15.107 and if applicable §15.107) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating.
Furthermore the module should be transmitting and the evaluation should confirm that the module’s intentional emissions (15C) are compliant (fundamental / out-of-band).  Finally the integrator has to apply the appropriate equipment authorization (e.g. Verification) for the new host device per definition in §15.101.

Module statement
The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of § 15.212(a)(1) as summarized below.

  1. The radio elements have the radio frequency circuitry shielded.
  2. The module has buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal.
  3. The module contains power supply regulation on the module.
  4. The module contains a permanently attached antenna.
  5. The module demonstrates compliance in a stand-alone configuration.
  6. The module is labeled with its permanently affixed FCC ID label.
  7. The module complies with all specific rules applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee.
  8. The module complies with RF exposure requirements.

This transmitter/module must not be collocated or operating in conjunction with any other antenna or transmitter.
