FCC Notice;

This module is intended for OEM integrators only. Per FCC KDB 996369 D03 OEM Manual v01 guidance, the following conditions must be strictly followed when using this certified module:

KDB 996369 D03 OEM Manual v01 rule sections:

1. List of applicable FCC rules
   This module has been tested for compliance to FCC Part 15 Subpart C

2. Summarize the specific operational use conditions
   This module designed for mounting inside of the end product by end product manufacturer professionally. Therefore, it complies with the antenna and transmission system requirements of §15.203.

3. Limited module procedures
   This module is certified as limited modular approval as it does not have its own power supply regulator, therefore regulated 3.3V/5.0V must be supplied by a host device using voltage regulator, e.g. NCV1117STAT3G or equivalent. The antenna must be installed inside the host device by a professional installer. Also, the antenna connector must be installed in such a way that it cannot be touched by the general public.

4. Trace antenna designs
   Not applicable.

5. RF exposure considerations
   This transmitter must not be co-located or operated in conjunction with any other antenna or transmitter except for SX-SDMAX（FCC ID: N6C-SDMAX）.
   The following statements must be described on the user manual of the host device of this module;
   This equipment complies with FCC mobile radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator & your body. If the module is installed in a portable host, a separate SAR evaluation is required to confirm compliance with relevant FCC portable RF exposure rules.

6. Antennas
   The following antennas have been certified for use with this module; antennas of the same type with equal or lower gain may also be used with this module. The antenna must be installed such that 20 cm can be maintained between the antenna and users. Antenna Type| Antenna Gain
   ---|---
   Rod| +3.4dBi

The antenna must be installed inside the host device by a professional installer. Also, the antenna connector must be installed in such a way that it cannot be touched by the general public.

7. Label and compliance information
   The final end product must be labeled in a visible area with the following: “Contains FCC ID: N6C-SDMAH”. The grantee’s FCC ID can be used only when all FCC compliance requirements are met.
   FCC CAUTION
   Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

8. This device may not cause harmful interference, and

9. this device must accept any interference received, including interference that may cause undesired operation.

10. Information on test modes and additional testing requirements
    This transmitter is tested in a standalone mobile RF exposure condition and any co-located or simultaneous transmission with other transmitter(s) not allowed or portable use will require a separate class II permissive change re- evaluation or new certification.

11. Additional testing, Part 15 Subpart B disclaimer
    This transmitter module is tested as a subsystem and its certification does not cover the FCC Part 15 Subpart B (unintentional radiator) rule requirement applicable to the final host. The final host will still need to be reassessed for compliance to this portion of rule requirements if applicable.

12. Note EMI Considerations
    We recommend to use “best practice” RF design engineering testing and evaluation in case non-linear interactions generate additional non-compliant limits due to module placement to host components or properties. The host manufacturer is responsible for ensuring compliance with the applicable FCC rules for the transmitters operating individually and simultaneously. This includes compliance for the summation of all emissions from all outputs occupying the same or overlapping frequency ranges, as defined by the applicable rules.

13. How to make changes
    Only the grantee is permitted to make permissive changes. Please contact us at Silex Technology, Inc.

As long as all conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed.

IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.

Manual Information To the End User

The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.

OEM/Host manufacturer responsibilities

OEM/Host manufacturers are ultimately responsible for the compliance of the Host and Module. The final product must be reassessed against all the essential requirements of the FCC rule such as FCC Part 15 Subpart B before it can be placed on the US market. This includes reassessing the transmitter module for compliance with the Radio and EMF essential requirements of the FCC rules. This module must not be incorporated into any other device or system without retesting for compliance as multi-radio and combined equipment.

Prohibited for control of or communications with unmanned aircraft systems, including drones.

Data transmission

Data transmission is always initiated by software, which is the passed down through the MAC, through the digital and analog baseband, and finally to the RF chip. Several special packets are initiated by the MAC. These are the only ways the digital baseband portion will turn on the RF transmitter, which it then turns off at the end of the packet.

Therefore, the transmitter will be on only while one of the aforementioned packets is being transmitted. In other words, this device automatically discontinue transmission in case of either absence of information to transmit or operational failure.

RF exposure considerations

The following statements must be described on the user manual of the host device of this module;
This equipment complies with ISED radiation exposure limits set forth for an uncontrolled environment and meets RSS-102 of the ISED radio frequency (RF) Exposure rules. This equipment should be installed and operated keeping the radiator at least 20cm or more away from person’s body.
