INTRODUCTION

This document describes the steps that the OEM integrator must follow when designing and manufacturing a system utilizing the Open-Q 865 SOM Transmitter Module.
Failing to follow the instructions in this document may invalidate the FCC and IC (Industry Canada) certifications and authorizations of the Module for use in the U.S. and Canada.
The Module certifications described in this document apply only to radio conformance for the Module. The OEM integrator is responsible for all system- level EMI/EMC and Product Safety testing and certifications that apply to the host system in the U.S. and other countries where the system will be marketed or sold.

APPLICABLE MODULE

ADDITIONAL REGULATORY CONFORMANCE TESTING AND/OR SUBMISSIONS REQUIRED BY

THE INTEGRATOR

• The modular certifications apply to the radio conformance for the Module only. The OEM integrator is responsible for additional system-level EMI/EMC and Product Safety testing and certification that applies in the U.S. and other countries to the host system containing the Module. This includes but is not limited to Federal Communications Commission (“FCC”) Part 15 Class B Digital Emissions. These system-level EMC tests are to be done with the Module installed and included in the scope of the submission.
• Some of the countries for which modular certifications are provided require additional submissions, authorizations, or import permission by the system vendor or importer. The integrator is responsible for these additional actions.
• Modular radio certification is not possible in some countries. For such countries, OEM integrators must ensure radio certification for the end system is obtained, before placing the product on the market.

COMPLIANT/ALLOWABLE TX POWER SETTINGS

Any adjustments made to increase transmit power settings will invalidate all radio certifications for this module.

ALLOWABLE ANTENNAS TO USE WITH THE RADIO MODULE

The module is certified for use with certain antennas as described in this section.
Allowed Antenna Types:

1. Dipole antenna

Table 1 Allowed Maximum Gain (dBi) Dipole, Including Cable Loss

The required antenna impedance is 50 ohms.
Use of other antenna types or the same type of antenna but with higher gain than listed above is not allowed without additional testing and appropriate FCC or IC approval.

ANTENNA PLACEMENT AND RF SAFETY

The FCC and other countries’ regulatory bodies impose strict conditions and limitations on the RF exposure levels of end products. Acceptable RF exposure levels for this Module depend on transmit power, the location of the transmitting antenna(s) inside the host system, and the expected separation of the transmitting antennas to the end-user. OEM integrators must take great care to ensure each host system complies with the applicable RF exposure requirements.
The antenna-to-user (bystander) separation distance must be greater than 20 cm and for FCC greater than 21 cm for ISED.
Failure to adhere to these separation/spacing rules will invalidate the FCC and IC certifications for the Module.
This separation is measured between the closest point of each transmitting antenna inside the host device to the point of contact by the user or nearby person outside the host device.

• The transmitting antenna cables shall be positioned away from the antenna elements to conform to the configuration tested for compliance.
• When transmitting antennas are installed in the display section of a device, the display section shall not have metallic components and material that can influence or change the operating and RF exposure characteristics of the antennas.
• The separation between the main and aux antennas must be at least 3 cm. The transmitter module may not be co-located with any other transmitter or antenna.
• SAR evaluation is required if a separation distance of less than or equal to 20cm
  between the user or bystanders and the device, the antenna cannot always be maintained. For ISED, bystander SAR evaluation is always required for antenna installation in laptop screens per RSS-102 (SPR)-001.

Where one or more of the conditions above cannot be met for a particular host system, additional testing is required to secure the necessary certifications for the system.
Note: These restrictions do not apply to the receive-only antennas.

SIMULTANEOUS TRANSMISSION WITH OTHER INTEGRATED OR PLUG-IN RADIOS

The FCC and IC impose conditions and limitations when additional radio(s) are co-located in the same host system as the Module with the capability to transmit simultaneously. Colocating other radios such as an integrated or plug-in Wireless WAN/cellular radio with the Module requires additional evaluation and possibly submission for authorization from the FCC and

Because the rules are highly dependent on the characteristics of the particular radios that are co-located and simultaneously transmitting, the OEM integrator should seek guidance from a knowledgeable test lab or consultant to determine if additional testing and certification is required. In this case, failure to evaluate and follow the required FCC and IC procedures will invalidate the FCC and IC certifications of the Module and end system.

MODULE MAY NOT BE INSTALLED BY END-USERS

FCC and IC rules require this Module to be installed in host systems at the factory by the OEM integrator. Thus, end-users of the system may not install the Module. Therefore, the host product user instructions must not advise the end-user on how to access or remove the Module. Additional FCC authorization/filing is needed to allow end-user installation of the radio modules.
If modules are provided to the end-users for installation in the host, a two- way authentication protocol is required to limit the module to operate only with the authorized host system.

REQUIRED LABELING ON THE OUTSIDE OF THE HOST

FCC Labeling Requirements on the Outside of the Host

The FCC requires a label on the outside of the host system visible to the end- user. Example wording is:
Contains: FCC ID: R68OQ865S IC: 3867A-OQ865S
The FCC requires a logo signifying emission compliance on the outside of the host system. The OEM integrator is responsible to perform FCC Part 15 Class B digital emissions testing on the end system with the radio Module installed. The FCC logo below should not be affixed unless the OEM integrator has obtained the necessary Part 15 approval, e.g., self-declaration of conformity.
If the host system is approved to FCC Class B digital emissions limits under a grant of certification issued by a TCB, the FCC ID number shown on the grant should be used on the label instead of the FCC logo below.

Also see https://www.fcc.gov/logos. A certified modular has the option to use a permanently affixed label, or an electronic label (Refer to FCC KDB 784748 D02 e labeling for e-labeling guidance). All modules without an integrated display on the module must be labeled with a module’s FCC ID – Section 2.926.

Industry Canada Labeling Requirements on the Outside of the Host

End Product Labeling The final end product must be labeled in a visible area with the following for the Open-Q 865 SOM: Contains IC: 3867A-OQ865S.
