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, 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.

• 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)

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 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 in accordance with 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.

  • Type: PCB Trace Antenna
  • Max. peak Antenna gain
    BT Ant: 2.90 dBi (2402 – 2480 MHz)

Any new antenna type, higher gain than listed antenna should be met the requirements of FCC rule 15.203 and 2.1043 as permissive change procedure.

• Label and compliance information

• 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 final end product must be labeled in a visible area with the following:
  • Contains FCC ID: BEJ-MB3021
  •  BEContains IC: 2703H-MB3021

• 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.

RSS-GEN, Sec. 7.1.3–(licence-exempt radio apparatus)
This device complies with Industry Canada licence-exempt RSS standard(s). Operation
is subject to the following two conditions:

1. this device may not cause interference, and
2. this device must accept any interference, including interference that may cause undesired operation of the device.

CE Statement
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
