FCC 15.203 Declaration Letter to Clarify the connector type Product: Modular Radio (Marketing name: TW-135, HVIN: ASY0750130) FCC ID: 2A6X2-135 Attestation Date: May 5, 2026 1. Applicability of Section 15.203 This device employs a standard female TNC connector that is externally accessible. Under normal consumer operation, Section 15.203 prohibits such user-accessible standard connectors. However, the professional-installation exemption in KDB 353028 D01 §II.A.2.c is invoked because: • The equipment is sold exclusively to trained personnel, military or authorized agencies, not to the general public. • Installation, calibration, and antenna attachment must be performed by trained professionals contracted by the licensee. • Users are explicitly prohibited from changing the antenna; the connector is only accessible by trained service personnel. 2. Professional Installation Justification Per KDB 353028 D01 guidance, justify as follows: 1. Controlled distribution o The radio module is not sold via retail or mail-order; it is issued exclusively through authorised channels to military or trained agency personnel. 2. Sophisticated installation requirements o Installation includes verifying field strength, configuring power levels, applying antenna- specific calibration, and ensuring RF exposure compliance in mission-specific configurations—tasks that require technical training and are not performed by end users. 3. Connector access limitation o Although externally located, the connector is ruggedized and access for user swap-out is prohibited by the user manual and physical design to prevent unauthorized antenna attachment. 3. Compliance Measures To meet KDB 353028 and §15.203: • Exhibit list of approved antennas including part numbers, vendor, type, maximum gain, feed-line specs, and matching cable length (only these antennas may be used). • Manual statement: “This device must be professionally installed. Unauthorized antenna attachment or connector access by end users is strictly prohibited.” 4. Grant Condition Statement (FCC Label/User Manual) The following verbiage is stated in the user manual: “This device must be professionally installed. Only approved antennas listed in this manual are permitted. End-users must not disconnect or replace the antenna connector.” Summary Table Requirement Compliance via Declaration FCC §15.203 standard connector Exempted via professional-installation justification KDB 353028 D01 guidance Met through controlled distribution, training requirements, connector access limitations Approved Antenna Listing required Exhibit included listing allowed antennas User/manual statement required Included clear prohibition on end-user antenna change Sincerely, Dated: May 5, 2026 Signed by: Print name: Mike Rudeen Mike Rudeen Title: Project Engineer Phone: (858) 753-1600 On behalf of: Company name: TrellisWare Technologies Inc.

Executive Summary This report presents the Maximum Permissible Exposure (MPE) analysis to demonstrate compliance with FCC RF exposure requirements. The evaluation considers both single transmitter operation and simultaneous multi-transmitter scenarios where applicable. 2. Key Findings Compliance status Complies Critical separation distances 67 cm Special conditions or limitations N/A MPE calculation report Product info: FCC ID: 2A6X2-135 Model: TW-135 Page 4 of 6 MPE calculations for stand-alone transmission Device Classification Requirements Portable Device Definition (§2.1093) Devices designed for use by a person where the radiating structure is within 20 cm of the user's body require SAR evaluation rather than MPE calculation. Mobile Device Definition Devices installed in vehicles or with permanently installed antennas may use MPE calculations if minimum separation distances can be established. Fixed/Base Station Definition Stationary transmitters with controlled access to antenna locations may use MPE calculations for both occupational and general population exposure scenarios. 3. References, definitions and limits for FCC FCC §2.1091(d) (2) For operations within the frequency range of 300 kHz and 6 GHz (inclusive), the limits for maximum permissible exposure (MPE), derived from whole-body SAR limits and listed in Table 1 in paragraph (e)(1) of this section, may be used instead of whole-body SAR limits as set forth in paragraphs (a) through (c) of this section to evaluate the environmental impact of human exposure to RF radiation as specified in §1.1307(b) of this part, except for portable devices as defined in §2.1093 of this chapter as these evaluations shall be performed according to the SAR provisions in §2.1093.

Power density calculation formula The fundamental equation (from page 18 of OET Bulletin 65, Edition 97-01) for calculating power density at a specified distance from an RF source is derived from the far-field assumption: 푆= 푃퐺 4휋푅 2 where: • S = Power density (mW/cm² or W/m²) • P = Power input to antenna (mW or W) • G = Antenna gain (linear ratio, not dB) • R = Distance from radiation center (cm or m) This equation assumes: • Far-field conditions (R > 2D²/λ, where D is largest antenna dimension) are assumed at the evaluation distance of 20 cm • Isotropic power distribution (conservative approach) • Free-space propagation conditions • Worst-case antenna orientation Multiple Transmitter Analysis (if applicable) Total Exposure Ratio (TER) Calculation: TER = Σ(Si/Li) ≤ 1.0 Where: • Si = Power density from transmitter i • Li = Applicable limit for transmitter i 5.…
