FCC Statement

This Module complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
(1) this module may not cause harmful interference, and (2) this module must accept any interference received, including interference that may cause undesired operation. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
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.  his 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 important announcement
Radiation Exposure Statement
The module has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.
Important Note:
In the event that these conditions cannot 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 cannot 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.
End Product Labeling
The final end product must be labeled in a visible area with the following” Contains FCC ID: SMQSD6-MAIN “.
Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01r01
List of applicable FCC rules
CFR 47 FCC PART 15 SUBPART C has been investigated. It is applicable to the modular transmitter.
Specific operational use conditions
This module is stand-alone modular. If the end product will involve the Multiple simultaneously transmitting condition or different operational conditions for a stand-alone modular transmitter in a host, host manufacturer have to consult with module manufacturer for the installation method in end system.
Limited module procedures
This module will only use in Edan Instruments, Inc’s host device only. We will retain control over the final installation of the modular such that compliance of the end product is assured. In such cases, an operating condition on the limit modular approval for the module must be only approved for use when installed in devices produced by a specific manufacturer. If any hardware modify or RF control software modify will be made by host manufacturer, C2PC or new certificate should be applied to get approval, if those change and modification made by host manufacturer not expressly approved by the party responsible for compliance, then it is illegal.
Trace antenna designs
Please refer to the chart below for main board PCB layout design.
The trace between module PIN30 and antenna must be 50 ohm impedance. At the same time, the antenna and module’s PIN30 are reserved for a PI type matching network, which is used for the matching and debugging of the antenna. The series of devices in the PI network can be used for 0 ohm, and parallel devices can not be used, If the device don’t need to tune the antenna.

RF exposure considerations
The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.
Antennas
This radio transmitter has been approved by Federal Communications Commission to operate with the antenna types listed below, with the maximum permissible gain indicated. Antenna types not included in this list that have a gain greater than the maximum gain indicated for any type listed are strictly prohibited for use with this device.

Label and compliance information
The final end product must be labeled in a visible area with the following “Contains FCC ID:SMQSD6-MAIN “.

Information on test modes and additional testing requirements
When install this modular with limit modular approval, Edan Instruments, Inc will perform the test of radiated emission and spurious emission according to FCC part 15C:15.247 and 15.209 requirement, only if the test result comply with FCC part 15.247 and 15.209 requirement, then the host can be sold legally.
Additional testing, Part 15 Subpart B disclaimer
Edan Instruments, Inc is responsible for compliance of the host system with module installed with all other applicable requirements for the system such as Part 15 B.
Note EMI Considerations
When integrating the module to the host device. Edan Instruments, Inc will use D04 Module Integration Guide recommending as “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 For standalone mode, reference the guidance in D04 Module Integration Guide and for simultaneous mode; see D02 Module Q&A Question 12
How to make changes
This module will only use in Edan Instruments, Inc’s host device only.
