Modular Approval Statement
Regulatory notice to host manufacturer according to KDB 996369 D03 OEM Manual

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 below this instruction manual.

Limited module Procedures This module is certified as limited modular approval because of lack of both conditions of SMA type connector antenna and power supply regulation, so the host manufacturer needs to be followed the installation guidance explained below.

1. Antenna Installation Guidance

1. The host device equipped with this transmitter module must be installed by a professional installer who is trained regarding the antenna installation conditions as outlined below:.
2. The antenna used must be used in the specified antenna type and maximum antenna gain as listed below: -. Antenna type: Half Wave dipole -. Max. peak Antenna gain: 2.1 dBi
   If a different type or higher gain antenna is used, additional authorization is required.
3. The OEM manufacturer, responsible for installing this module into the host device, must ensure that end-users do not have access to the antenna and connector, in compliance with FCC Section 15.203.
4. the antenna connector must not be accessible to the end-user when installed into the host device and the host device must ensure the module and antenna are installed in accordance with the installation guidance.

2. Installation guidance for power supply regulation This module does not have its own power supply regulation. Therefore, Host product in which this module is installed must be followed module manufacturers installation guidance to provide the correct input voltages (2.7-3.6 Vdc) to this module from host devices power supply regulation circuitry. Verification testing shall be performed according to the provided test guidance in this documents. This is to ensure that the module, when installed and operated under the host products operating conditions and voltage regulation range, remains compliant with FCC requirements.
Host Product Test Guidance
: The radiated signal level of the fundamental frequency and radiated spurious emissions measurements shall be performed while varying the hosts supply voltage between 85% and 115% of the nominal rated supply voltage. For battery operated equipment, the equipment tests shall be performed using a new battery. At low battery voltage levels, the

module input level may drop to 0V, otherwise shall be maintained within the operating voltage range. The verification testing results while varying the host operating voltages must be meet the following criteria: – The radiated signal level of fundamental frequency bands (920.1375MHz~922.6625 MHz) must be lower than 26.1 dBm EIRP (Conducted power 24 dBm + peak Antenna gain 2.1 dBi). – Radiated spurious emissions measurements must be lower than module`s highest value in the harmonic frequencies of fundamental frequency bands.

Trace antenna designs – This module is using Trace Antenna Design. Module integration guidelines must be closely followed. Compliance of host integrations of the module is limited to hosts adaptation designs which are identical to SJIT’s reference designs explained in this documents. Host integrations with adaption designs deviating from SJIT`s reference design require either class 2 permissive change to this modular approval or a separate host approval with different FCC ID.
Antennas list The antenna certified with this module is listed following.
-. Antenna type: Half Wave dipole (Model name: INNO-EL9SWS-149)
-. Max. peak Antenna gain: 2.1 dBi
A host manufacturer must not use the other types of antenna and an antenna with a gain that exceeds the values listed below
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.
End Product Labeling The module is labeled with its own FCC ID. If the FCC ID 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: 2BEK7SFM10R4 Contains IC: 32019-SFM10R4
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.
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 or change RF related parameters in the user manual of the end product.
Note EMI Considerations Note that a host manufacture is recommended to use D04 Module Integration Guide recommending as “best practice” RF design engineering testing and evaluation in case non-linear interactions generate additional noncompliant 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, which permits the host manufacturer to confirm compliance. How to make changes Since only Grantees are permitted to make permissive changes, when the module will be used differently than granted, please contact the module manufacture on below contact information. -. Contact information: wskim@seongji.co.kr/ +82-31-223-7048
l’exposition aux RF L’antenne (ou les antennes) doit être installée de façon à maintenir à tout instant une distance minimum de au moins 20 cm entre la source de radiation (l’antenne) et toute personne physique.
Étiquetage du produit final Le module SFM10R4 est étiqueté avec sa propre identification ISED et son propre numéro de certification IC. Si l’identification ISED et le numéro de certification ISED ne sont pas visibles lorsque le module est installé à l’intérieur d’un autre dispositif, la partie externe du dispositive dans lequel le module est installé devra également présenter une étiquette faisant référence au module inclus. Dans ce cas, le produit final devra être étiqueté sur une zone visible avec les informations suivantes : « Contient module émetteur IC : 32019-SFM10R4

1. Layout of trace design, parts, antenna, connectors, and isolation requirements; All RF trace must be 50 ohm line. Connectors must be SMA Type connector. And Antenna also
   must be dipole antenna manufactured by Inno-Link. Co., Ltd listed below. If difference type of connector other than SMA type or antenna other than the antenna listed below is used, additional authorization through either Class II Permissive change or new authorization procedure is required. The OEM manufacturer, responsible for installing this module into the host device, must ensure that end-users do not have access to the antenna and connector, in compliance with FCC Section 15.203.
2. Boundary limits of size, thickness, length, width, shape(s), dielectric constant, and impedance must be clearly described for each type of antenna; Antenna can be used only SMA type antenna manufactured by Inno-Link Co., Ltd.. Different antenna type is not acceptable.
3. Different antenna length and shapes affect radiated emissions, and each design shall be considered a different type; e.g., antenna length in multiple(s) of frequency wavelength and antenna shape (traces in phase) can affect antenna gain and must be considered; Different antenna is unacceptable.
