All sales for these devices must be under a NDA restricting the disclosure of the propriety information. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of 180 days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify TUV Rheinland in the event information regarding the product or the product is made available to the public. TUV Rheinland will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705. Sincerely, By: Hideki Kato (Signature/Title) (Print name)

Applicant/GranteeTAIYO YUDEN CO., LTD. FCC ID:RYYEYSSSN Section 15.212 Modular Transmitters / X Request for Modular Approval RequestforLimitedModularApproval Requirements Device Conditions Comply (Y/N) SingleModularApproval Requirements 1 The radio elements must have the radio frequency circuitry must be shielded. Physical/discrete and tuning capacitors may be located external to the shield, but must be on the module assembly. The module has its own RF shielding.” Shield Can is employed on the board structure, please see exhibition External Photo, the emission measurement was conducted without further shielding added. Y 2 The module shall have buffered modulation/data input(s) (if such inputs are provided) to ensure that the module will comply with the requirements set out in the applicable RSS standard under conditions of excessive data rates or over-modulation. All modulation and data input(s) are buffered.” The EUT has buffered data inputs, it is integrated on the RF chip Y 3 The module shall have its own power supply regulation on the module. This is to ensure that the module will comply with the requirements set out in the applicable standard regardless of the design of the power supplying circuitry in the host device which houses the module. Requirements set out in the applicable standard regardless of the design of the power supplying circuitry in the host device which houses the module. Output power is controlled by the RF Chip and de-coupled from supply voltage variations. Frequencies are determined by Crystal Y 4 The module shall comply with the provisions for external power amplifiers and antennas detailed in this standard. The Equipment certification submission shall contain a detailed description of the configuration of all antennas that will be used with the module. The antenna is part of the module Y 5 The module shall be tested for compliance with the applicable standard in a stand- alone configuration, i.e. the module must not be inside another device during testing. The modular transmitter was tested in a stand-alone configuration via a UART Interface. Y 6 The module shall comply with the Category I equipment labelling requirements. In the exhibition OEM manual, there are Instructions given to the OEM on how to label the end product. Y 7 The modular transmitter complies with all specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer will provide adequate instructions along with the module to explain any such requirements. A copy of these instructions is included in this application for equipment authorization: Instructions in User Manual Y 8a Address compliance with the Commission's RF exposure limits in Sections 1.1310 and 2.1093. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF exposure compliance in accordance with Section 15.247(b)(4). Please refer the Maximum Permissible Exposure Information. Y A limited modular approval may be granted for single or split modular transmitters that do not comply with all of the above requirements, e.g., shielding, minimum signaling amplitude, buffered modulation/data inputs, or power supply regulation, if the manufacturer can demonstrate by alternative means in the application for equipment authorization that the modular transmitter meets all the applicable Part 15 requirements under the operating conditions in which the transmitter will be used. Limited modular approval also may be granted in those instances where compliance with RF exposure rules is demonstrated only for particular product configurations. The applicant for certification must state how control of the end product into which the module will be installed will be maintained such that full compliance of the end product is always ensured.

HD-AD- Description of laser Markingunit:mm 1) Model (upper 6 digits): EYSSSN 2) User-Code 3) Manufacturer : TAIYO YUDEN 4) 1pin mark 5) Product Lot number: Four digits (Refer to [Instruction for Lot Number]) It is impossible to put a label on this very small shielding part. Therefore the marking of model number and user code is written by LASER marker. It needs to consider about alignment accuracy as well. The traceability requirement in quality control under ISO standard is secured by the Lot number, the Model number and user code marking on each product. The marking can be not removed by our company regulation for product management. Putting on this together, marking of ID number on this shielding part with 3.25mm width is impossible. It's describe on a user's manual because it isn't possible to indicated " FCC:RYYEYSSSN ". TAIYO YUDEN CO.,LTD.
