OEM Responsibilities to comply with FCC Regulations
This module has been tested for compliance to FCC Part 15. It has been tested
as a subsystem, and its certification does not cover the FCC Part 15 Subpart B
(unintentional radiator) rule requirement.
OEM integrators are responsible for testing their end-product for any
additional compliance requirements needed with this module installed (e.g
radiated emissions).
nd Product Labeling
§ 15.19 Labelling requirements shall be complied on the end user device.
Labelling rules for special devices, please refer to §2.925, § 15.19 (a)(5)
and relevant KDB publications.
For E-label, please refer to §2.935.
Information on test modes and additional testing requirements
The OEM integrator is responsible for ensuring that the end-user has no manual
instruction to remove or install the module. The module is limited to
installation in mobile applications, a separate approval is required for all
other operating configurations, including portable configurations with respect
to §2.1093 and different antenna configurations.
Test software to access different test modes: p2radio
Testing item, frequencies, transmit power, modulation type can be selected
following the test script instructions.
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: 2AFXO-EUREKA”
- “Contains Transmitter Module FCC ID: 2AFXO-EUREKA”
The OEM integrator is responsible for ensuring that no information is provided
to the end user regarding how to install or remove the module or how to change
RF related parameters.
Class B Device Notice – Part 15B Compliance Requirements for Host product

the statement set out in §15.105 Information to the user or such similar
statement and place it in a prominent location in the text of the host product
manual. Original texts as following:
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.
