September 20, 2024 Nemko North America, Inc. 303 River Road, Ottawa, Ontario, Canada K1V 1H2 Attn: Director of Certification Request for Confidentiality – FCC FCC ID: W6UER17192325N Pursuant to FCC 47 CFR 0.457(d)(1)(ii) and 0.459 and FCC guidance published in KDB 726920, we hereby request confidential treatment of information accompanying this application as outlined below. We request the exhibits selected below as long term confidential (LTC) be withheld from public view permanently: Selection of exhibits for LTC - general Exhibit name ☒ Permanent (Long Term) Block Diagrams ☒ Permanent (Long Term) Operation Description / Theory of Operation ☒ Permanent (Long Term) Parts List & Placement / BOM ☒ Permanent (Long Term) Schematics ☒ Permanent (Long Term) Tune-Up Procedure Selection of exhibits for LTC (with NDA) 1 Exhibit name ☒ Permanent (Long Term) User’s Manual ☒ Permanent (Long Term) Internal Photos Justification for Long-Term Confidentiality for User manual and Internal photos: 1. Limited Accessibility: The device in question is not accessible to the general public. It is designed to be serviced exclusively by professional, designated technicians who are bound by a Non- Disclosure Agreement (NDA) and who are trained and certified in the use and commissioning of this equipment. 2. Competitive Advantage: The user manual is being requested to be confidential under the FCC guidelines that the manual is very technical and is not provided to the general public. The user manual contains proprietary information required for trained installers to commission the DAS. The user manual will be used by the licensee or his designated technicians only. Having the subject information easily available to competitors would negate the advantage we have achieved by developing this product. 1 - These items require further information to be provided to TCB before permanent confidentiality will be extended to these exhibits. Please refer to FCC KDB 726920 and review section II, 3) regarding specific information (NDA) that must accompany these requests. We also request the exhibits selected below as short term confidential (STC) be withheld from public view for a period of 180 days 2 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: Selection of exhibits for STC 3 Exhibit name ☒ Short Term External Photos ☒ Short Term Test Setup Photos Our company has spent a substantial effort in developing this product and it is one of the first of its kind in the industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. When the device is marketed before the requested number of days listed above, the grantee will inform the TCB to release the Short-Term Confidentiality information withheld on the FCC equipment authorization website. The above information contains trade secrets and proprietary information not customarily released to the public. The public disclosure of this information might be harmful to the applicant and provide unjustified benefits to its competitors. The Applicant understands that pursuant to Rule 0.457(d)(1)(ii), disclosure of this Application and all accompanying materials will not be made before the date of the Grant for this Application.

This MNDA is effective for both preliminary discussions between the Parties prior to the development of a contractual relationship, and shall also govern the subsequent exchange of any and all confidential and/or proprietary information between the Parties during any such relationship, if any. In entering into this MNDA, the Parties acknowledge that neither would disclose such information to the other unless the other agreed to maintain such information in confidence. NOW, THEREFORE, in reliance upon and in consideration of the following undertakings and the mutual benefits to be derived therefrom, the Parties agree as follows: 1.

Use of Confidential Information Each Party agrees to use Confidential Information received from the other only for purposes of determining whether to enter into a mutual business relationship concerning certain products or services, in fulfillment of any other written agreement between the Parties, or for any other purpose specifically identified in writing and mutually agreed upon by the Parties. The Parties agree not to reveal each other's Confidential Information to any third party, or to reveal the contents of this MNDA to any third party, without the other's prior written consent. As a condition of granting such consent, the other Party may require the third party to execute an agreement in substantially the same form as this MNDA. Unless prior written consent is obtained, the Parties agree to disclose Confidential Information received from one another only to representatives, officers, employees or agents of the receiving Party who have a “need to know” such Confidential Information for the purposes set forth above. 3. Copying Confidential Information Except for internal distribution on a “need to know” basis as set forth above, the Parties agree not to copy or otherwise reproduce any written Confidential Information without the express prior written consent of -2- the disclosing Party. In any event, all such Confidential Information and copies thereof shall remain the sole property of the disclosing Party, and all copies (including internal copies) shall be promptly returned to the disclosing Party when: (a) the receiving Party's need for it has expired, or (b) upon the disclosing Party's request. 4. Compliance with Laws The Parties shall comply, and do all things necessary to enable the other to comply, with all applicable Federal, State and local laws, regulations and ordinances, including but not limited to, the Regulations of the United States Department of Commerce relating to the Export of Technical Data, insofar as they may relate to the activities to be performed by the parties. The Parties agree to obtain any and all required government documents and approvals prior to the exportation of any Confidential Information, which includes such technical data disclosed by the other. 5. Care of Confidential Information All Parties shall provide the same type and degree of care to prevent disclosure or unauthorized use of the other Party's Confidential Information, as they would provide to protect their own confidential information. As a minimum requirement, the Parties shall retain each other's Confidential Information in one or more secure places with access limited only to their respective representatives, officers, employees or agents who have a “need to know” such Confidential Information for the purposes set forth above. 6. Exceptions to Confidential Information Notwithstanding the definition contained in Section 1 herein, the term “Confidential Information” does not include information which: A. has been published by the disclosing Party or is otherwise in the public domain through no fault of the receiving Party; B. is properly within the legitimate possession of the receiving Party prior to its disclosure hereunder and without any obligation of confidence; C. after disclosure by the disclosing Party, is lawfully received by the receiving Party from a third party having rights in such Confidential Information and such third party was not restricted from disclosing the information to the receiving Party her…
