Yamamoto CKC Laboratories, Inc. 5046 Sierra Pines Drive Mariposa, CA 95338 The test data contained in this report documents the observed testing parameters pertaining to and are relevant for only the sample equipment tested in the agreed upon operational mode(s) and configuration(s) as identified herein. Compliance assessment remains the client’s responsibility. This report may not be used to claim product endorsement by A2LA or any government agencies. This test report has been authorized for release under quality control from CKC Laboratories, Inc. Steve Behm Director of Quality Assurance & Engineering Services CKC Laboratories, Inc. Page 2 of 6 Report No: 107284-9 Purpose: To demonstrate compliance with United States RF Exposure requirements for Portable equipment (devices used ≤20cm from the body) with power output below exemption levels or Mobile equipment (devices used >20cm from the body) where Maximum Permissible Exposure (MPE) Calculations apply. Device and Antenna Operating Configuration: Device operating at maximum output power with continuous transmission of modulated data. Method: This equipment is evaluated in accordance with the guidelines set forth in 47 CFR 1.1310, KDB 447498 & ANSI C95.1 for the US. Other Considerations: Report considers stand-alone equipment configurations only. RF Exposure limits are calculated at the mid-point of each operating band. Referenced Test Reports: The following test reports were referenced in conjunction with this assessment: 107284-4 Decision Rule: Outcome of RF exposure assessment is listed in the comment section(s) below as a binary statement for simple acceptance rule according to ILAC-G8 (2019).

Additional configurations including collocation or simultaneous transmission with other transmitters (including necessary separation distances) are subject to further assessment. Certain exemption criteria may define specific separation distances. It is assumed that the manufacturer shall design the equipment such that these minimum separation distance is met. MPE Calculation Results: Equipment demonstrating compliance with MPE calculations have been evaluated, without further testing, for use under mobile RF exposure configurations as identified herein. Additional configurations including collocation or simultaneous transmission with other transmitters (including necessary separation distances) are subject to further assessment. It is assumed that the manufacturer shall design the equipment such that the minimum separation distance of 20cm (or greater, as listed above) is met or that the manufacturer provides a protection guide (e.g. installation instructions) to the end user such that the antenna(s) may be installed in accordance with the manufacturer’s instructions in such a manor to maintain the minimum separation distance. General Comments: The absorption and distribution of Electromagnetic energy in the body is a very complex phenomena that depends on the mass, shape and physiological condition of the body; the orientation of the body with respect to the fields; and, the electrical properties of the body and the environment. Variables that may play a substantial role in possible biological effects are those that characterize the environment (including but not limited to: ambient temperature, air velocity, relative humidity and body insulation); and those that characterize the individual (including but not limited to: age, gender, activity level and existing debilitation or disease). Because innumerable factors may interact to determine specific biological effects of exposure to electromagnetic fields, any protection guide should consider both intended and unintended operational environments and provide guidance for installation and use of the equipment such that proper separation distances can be maintained.
