Sincerely, John Becker Principal Electrical Engineer Fortell Research Inc. [email protected]

Fortell Research Inc. +1 (833) 445-1455 379 W Broadway New York, NY 10012 October 06, 2025 Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Subject: Justification for Alternate FCC ID Labeling FCC ID: 2BRSV-FR1RICRA To Whom It May Concern: Fortell Research Inc. respectfully submits this letter to justify the placement of the FCC ID label for the above- referenced device. Our Hearing Aids have physical dimensions too small to apply a permanent, legible label with the required FCC ID information in a 4-point font or larger. The critical dimensions and limited surface area available on the product's exterior make it impractical to meet standard on-device labeling requirements. Therefore, in accordance with FCC regulations, specifically KDB Publication 784748 D01 and 47 CFR 2.925(f), we will use the following alternative labeling method: 1. FCC ID in User Manual: The FCC Identifier will be clearly and prominently included in the device's user manual. 2. FCC ID on Packaging: The full FCC ID will be printed on the device's retail packaging. • 2. 3. Mobile App: The full FCC ID will be listed in the mobile app device information. • Account > Device Information: • The FCC ID will be easily accessible to the user through the provided manual, mobile app, and the product packaging, ensuring that all regulatory requirements are met. Thank you for your consideration of this request. Sincerely, John Becker Principal Electrical Engineer Fortell Research Inc. [email protected]

Report No. CHRM0004.56/10 RF EXPOSURE CONDITION 2018-07-17 The following RF Exposure conditions were used for the assessment documented in this report: Intended Use Portable Location on Body (if applicable) Head/Torso How is the Device Used Hearing aid is worn on the ear at a distance less than 20 cm from the user Radios Contained in the Same Host Device Bluetooth Low Energy Simultaneous Transmitting Radios None Body Worn Accessories n/a Environment General Population/Uncontrolled Exposure Report No. CHRM0004.57/10 SAR TEST EXCLUSION EXRPT.2025.06.10.0 OVERVIEW Human exposure to RF emissions from portable devices (47 CFR §2.1093) used with the radiating antenna closer than 20 cm to the user requires Specific Absorption Rate (SAR) to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation. COMPLIANCE WITH FCC REQUIREMENTS IN 47 CFR §2.1093 The EUT will be used with a separation distance of less than 20 centimeters between the radiating antenna and the body of the user or nearby persons and must therefore be considered a portable transmitter per 47 CFR 2.1093(b). 47 CFR §2.1093 “(b) For purposes of this section, the definitions in §1.1307(b)(2) of this chapter shall apply. A portable device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that the RF source's radiating structure(s) is/are within 20 centimeters of the body of the user.” COMPLIANCE WITH FCC KDB 447498 D01 GENERAL RF EXPOSURE GUIDANCE V06 “KDB 447498 D01 General RF Exposure Guidance v06” provides the procedures, requirements, and authorizat…

The frequency ranges investigated (scanned), are also noted in this report. The EUT was placed on a low dielectric constant support structure (Phi Axis Positioner) in the 3D center of the measurement zone using a laser alignment system. The test begins with a measurement path configured (via ETS-Lindgren EMQuest Data Acquisition and Analysis Software) such that an electrical path is present from the Theta polarization element of the -165° detector antenna, to the measurement port of a spectrum analyzer. The EUT is commanded to transmit at the desired frequency and an absolute power measurement is obtained at the spectrum analyzer. The measurement path is then reconfigured (again via EMQuest) such that an electrical path is present from the Phi polarization element of the - 165° detector antenna, to the measurement port of the spectrum analyzer. Another absolute power measurement is obtained at the spectrum analyzer. This process is repeated at each of the 23 detector antennas in turn. This process is repeated for every rotation of the Phi Axis Positioner up to 180° - Phi Axis Resolution. When this process is complete, EMQuest applies factors from a Range Calibration and Normalization to produce a final data set with 1D/2D/3D patterns and tabular values such as antenna efficiency, Equivalent Isotropic Radiated Power (EIRP), Total Radiated Power (TRP), etc. A measurement uncertainty estimation has been performed for this testing. When a measurement is made, the result will be different from the true or theoretically correct value. The difference is the result of tolerances in the measurement system that cannot be completely eliminated. To the extent that technology allows us, it has been our aim to minimize this error. Measurement uncertainty is a statistical expression of measurement error qualified by a probability distribution. The expanded measurement uncertainty, 95% confidence level (K=2), for Maximum Gain / Efficiency for 2400-2483.5 MHz on active measurements is +/-1.08 dB. The expanded measurement uncertainty, 95% confidence level (K=2), for Maximum Gain / Efficiency for 2400-2483.5 MHz on passive measurements is +/-1.29. The calculations for estimating measurement uncertainty are available upon request. Procedures for the Range Calibration and Normalization can be found in Element Materials Technology document: WP Antenna Pattern Measurements (3D) Chamber - …
