Rosemount Inc. 8200 Market Boulevard Chanhassen, MN 55317 USA Attention: Application Examiner Re: Request for confidentiality Applicant: Rosemount, Inc. FCC ID: LW2RM25WM To whom it may concern, Permanent Confidentiality Request is hereby submitted by Rosemount, Inc. to withhold permanently from public review certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept permanently confidential: • Schematics • Detailed Block diagrams • Detailed Operational/Functional Description • Parts list • Internal photos • User Manual This device is a non-consumer device inaccessible to general public and is only accessable by qualified technical personnel in the industrial control industry. Short-term Confidentiality [Complete this section if short-term confidentiality is requested] Request is hereby submitted by Rosemount Inc. to withhold from public review for a period of 45 days from the date of the Grant of Equipment Authorization and prior to marketing, certain portions of the application for equipment certification for the referenced FCC identifiers. This request for confidentiality is made pursuant to 47 CFR 0.457(d) and 0.459 of the FCC Rules. In particular, the following sections of the application are to be kept confidential for a period of 45 days from the date of Authorization: • Test setup photos • External photos Rationale for request for confidentiality: Rosemount Inc. has invested considerable time and materials in research and development to produce the referenced product. Disclosure of the permanently confidential portions of this application to competitors would not only give them significant competitive advantages in developing similar products, but would also disclose successful implementation of unpublished, leading edge technology developed by us.: Disclosure of the short-term confidential portions of this application during the period of importation and/or distribution would reveal key aspects of proprietary technology to competitors and diminish the value of our investment in research and development. . The User Manual is only available to Rosemount business partners who have confidentiality agreements with us. Due to the detailed technical nature of the user manual it is considered confidential for the same reasons listed above. Sincerely, Principal Approvals Engineer Rosemount, Inc.

Rosemount Inc. 8200 Market Boulevard Chanhassen, MN 55317 USA Attention: Application Examiner Re: Justification of Modular Approval Applicant: Rosemount, Inc. FCC ID: LW2RM25WM To whom it may concern, Modular Transmitter Model RM25WM Request is hereby submitted by Rosemount, Inc. to certify the Wireless Hart Radio Module RM25WM as a Single Modular Transmitter under the applicable Industry Canada telecommunication rules. The following list shows compliance with each of the special requirements listed for modular approvals: • The Radio Elements must have the radio frequency circuitry shielded: The radio has a metal enclosure as can be seen in the photos • Buffered modulation/data inputs: The module uses the Linear Model DN2510 radio chip and it has buffered input and outputs • Power supply regulation: The module has DC power supply regulation as seen on the schematic • The module must contain a permanently attached antenna or contain a unique antenna connector: The module contains a MMCX connector that approved antennas can be connected. Since the module must be integrated into another enclosure, this connection is integral to the unit and not accessible to the end user. • Compliance in « Stand alone » configuration : This is demonstrated in the test report. • Permanent labeling : Per the module photos, the IC ID is permanently affixed to the module. • The module must comply with all specific rules applicable to the transmitter : See the test report and the user manual with the integration instructions. • RF exposure limits: See the test report. Sincerely, Principal Approvals Engineer Rosemount, Inc.
