OPERATION & MAINTENANCE OF THE MRC-565-15 GNSS PACKET DATA RADIO Rev.

Warranty-covered equipment that fails during the warranty period will be promptly repaired at MRC’s facility in Kent, Washington. International customers are required to pay shipping costs to the MRC facility, with Seattle as the point of U.S. entry. MRC will pay incoming U.S. duty fees. MRC will pay shipping costs to return the equipment to the customer, with the customer paying all return duty fees. This warranty is contingent upon proper use of the equipment and does not cover equipment that has been modified in any way without MRC’s approval or has been subjected to unusual physical or electrical stress, or on which the original identification marks have been removed or altered. Page 3 MRC-565 Packet Data Radio Operations & Maintenance EXPOSURE TO RF RADIATION The FCC guidelines limit the maximum permitted exposure to RF radiation for Occupational/ Controlled Exposure to 1 mw/sq. cm for frequency ranges of 30-300 MHz. This limit and the following equation for calculating field strength (obtained from OET Bulletin 65) is used to calculate the minimum separation between humans and the transmit antenna based on MPE S= P*G* DC/(4*π*R*R) P = Transmit power in milliwatts = 100,000 G = Antenna gain referenced to an isotropic radiator = 1.68 (2.2dbi) mobile quarter wave dipole mounted to fender/roof of automobile = 10.0 (10.0 dbi) fixed 5 element Yagi mounted to top of fixed antenna tower = 3.3 (5.2 dbi) fixed half wave dipole mounted to fixed antenna tower leg R = separation required cm DC = Maximum duty cycle of transmitter = 10 % S = Power density = 1 milliwatt/square cm This equation is accurate for the far field of an antenna, but will over-predict power density in the near field. Thus, the near field MPE distances calculated here are “worst case” or conservative. Antenna separation for mobile applications: The typical antenna used in mobile application has a maximum antenna gain of less than 2.2 dBi (¼ wave dipole or ½ wave dipole). To ensure safe operation the antenna must be mounted such that the separation between the antenna and any human occupants of the vehicle exceeds 0.90 meters (36”). The best location for antenna mounting is the center of the vehicle roof. This will provide additional RF shielding between the antenna and the human occupants that reduces the RF exposure to levels well below that specified in FCC OET Bulletin 65. When working on the antenna and or co-ax cable always disable the transmitter by turning its power off. Antenna separation for fixed applications: For fixed applications, antenna gains and mounting techniques can vary depending on the application. For Yagi antennas whose gain does not exceed 10 dBi, that antenna must be mounted a minimum of 2.2 meters from any humans occupants. Lower gain antennas, such as side mount dipoles, exhibit lower gain (5.2 dBi) allow closer separations (1.3 meters for 5.2 dBi antennas). This will provide RF shielding between the antenna and the human occupants that reduce the RF exposure to levels below that specified in FCC OET Bulletin 65. When working on the antenna and or co-ax cable always disable the transmitter by turning its power off.

A summary of these differences is given below: • Number of circuit boards MRC-565 has 2 MCC 545 has 3 • MRC-565 is a software defined radio with no adjustments on CMU board • The MRC-565 has a wideband (40-46 MHZ) FET-PA with adjustable power levels (10,25,50,100 watts) controlled by CMU commands. • No battery backed up RAM. No PWR FAIL RESTORE message • New LPM modes • Ethernet Port with TCP/IP • M8 Ethernet Port – connection to GNSS Daughter Board hosted on main processor board • USB Device Port for connecting to PC USB port. Requires Driver For the most part the MRC-565 operator commands are the same as the MCC 545B commands.

-11 RADIO FREQUENCY EXPOSURE REPORT FOR THE MRC565 Packet Data Radio Model: MRC565-15 Report No.: 104972-11 Date of issue: November 30, 2021 PREPARED FOR: Maiden Rock Communications Peter Donich 586 Double Arrow Road Seeley Lake, MT 59868 PREPARED BY: Matt Harrison 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 10 Report No: 104972-11 Purpose: To demonstrate compliance with United States, Canada, Australia and/or European Union 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. Test Procedure: This equipment is evaluated in accordance with the guidelines set forth in KDB 447498 & ANSI C95.1 for the US, Health Canada Safety Code 6 & RSS 102 for Canada, ARPANSA RPS3 for AU and EN 62479 or EN 62311 for EU. Other Considerations: Report considers stand-alone configurations only. RF Exposure limits are calculated at the mid-point of each operating band. Multi-transmitter devices are assumed to permit simultaneous transmission, unless indicated otherwise. Simultaneous transmissions aggregated providing a worst case assessment. Referenced Test Reports: The following test reports were referenced in conjunction with this assessment: 104972-4 Page 3 of 10 Report No: 104972-11 RF Exposure Power Density Assessment (Single Transmitter, Stand Alone) MPE Calculation: 푃표푤푒푟 퐷푒푛푠푖푡푦 ( 푆 ) = 퐸퐼푅푃 4휋 푑 2 Given: EIRP in mW or W and d in cm or m US MPE Assessment Power Reported is: ☒ Peak ☐ Average Limit Used is: ☒ General Population ☐ Occupational Exposure Operating Band MHz Power dBm Ant Type/Gain dBi EIRP dBm Distance cm MPE mW/cm 2 Limit mW/cm 2 Comments 40-46 40.3 Dipole / 2.2 dBi 42.2 90 0.17 0.20 Power utilizing 10% duty cycle. 40-46 40.3 Dipole / 5.2 dBi 45.7 130 0.17 0.20 Power utilizing 10% duty cycle. 40-46 40.3 Yagi / 10 dBi 50.3 220 0.18 0.20 Power utilizing 10% duty cycle. Page 4 of 10 Report No: 104972-11 Summary: Exemptions: Equipment demonstrating compliance by portable RF exposure exemption have been evaluated, without further testing, for use under either portable or mobile RF exposure configurations. 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 product such that proper separation distances can be maintained.
