FCC Part 15.211 Certification Reutech Mining Test Report SUBSURFACE PROFILER (SSP) December 2018 2.5 MEASUREMENT UNCERTAINTY All results reported herein relate only to the equipment tested. The basis for uncertainty calculation uses ANSI/NCSL Z540-2-1997 (R2002) with a type B evaluation of the standard uncertainty. Elements contributing to the standard uncertainty are combined using the method described in Equation 1 to arrive at the total standard uncertainty. The standard uncertainty is multiplied by the coverage factor to determine the expanded uncertainty which is generally accepted for use in commercial, industrial, and regulatory applications and when health and safety are concerned (see Equation 2). A coverage factor was selected to yield a 95% confidence in the uncertainty estimation. Equation 1: Standard Uncertainty a2 b2 c2 uc = ± 2 + 2 + 2 + ....... diva divb divc Where uc = standard uncertainty a, b, c,.. = individual uncertainty elements Diva, b, c = the individual uncertainty element divisor based on the probability distribution Divisor = 1.732 for rectangular distribution Divisor = 2 for normal distribution Divisor = 1.414 for trapezoid distribution Equation 2: Expanded Uncertainty U = ku c Where U = expanded uncertainty k = coverage factor k ≤ 2 for 95% coverage (ANSI/NCSL Z540-2 Annex G) uc = standard uncertainty The measurement uncertainty complies with the maximum allowed uncertainty from CISPR 16-4-2. Measurement uncertainty is not used to adjust the measurements to determine compliance. The expanded uncertainty values for the various scopes in the WLL accreditation are provided in Table 3 below.

FCC Part 15.211 Certification Reutech Mining Test Report SUBSURFACE PROFILER (SSP) December 2018 4 TEST RESULTS The plots below show the results of testing for compliance with a Tunnel Radio System in accordance with FCC Part 15.211 (9/2018). 4.1 RADIATED EMISSIONS: (FCC PART §15.211) Emissions must meet the general radiated emissions of 15.209. Per guidance received from the FCC, restricted band frequencies do not apply to 15.211 4.1.1 Test Procedure Pre-scans were performed at a distance of 3m to determine worst-case orientation of the device, which was with the roller long dimension perpendicular to the tunnel opening as shown in the test setup photo. The procedure was to monitor the emissions at the tunnel entrance until the quasi-peak levels dropped below the 15.209 limit. This distance was found to be 1193 feet or 364 meters. The measurement antenna was set up at the same location during the pre-scan and the final data measurement. WLL Report 15412-01 REV 2 Page-12 of 23-

FCC Part 15.211 Certification Reutech Mining Test Report SUBSURFACE PROFILER (SSP) December 2018 Figure 6. 3m Pre scan Maximum EUT orientation Vertical (Peak) The EUT was placed 364 meters inside the tunnel and oriented for maximum emissions that were determined at a 3m scanning distance. Receiving antennas were mounted on a tripod. The height of the antenna was set to 2 meters. The height of the antenna was scanned, but the emissions did not noticeably vary. Both the horizontal and vertical field components were measured. WLL Report 15412-01 REV 2 Page-14 of 23-

FCC Part 15.211 Certification Reutech Mining Test Report SUBSURFACE PROFILER (SSP) December 2018 The emissions were measured using the following resolution bandwidths: Table 5: Spectrum Analyzer Settings Frequency Range Resolution Bandwidth Video Bandwidth 30MHz-1000 MHz 120kHz >100 kHz >1000 MHz 1 MHz 1MHz (Peak) Cable correction, pre-amplifier and antenna factors were input into the spectrum analyzer. The spectrum analyzer readings in dBuV represent the actual field strength in dBuV/m. Peak readings are shown in the following figure. The peak-to quasi-peak difference was determined to be approximately 6.2 dB. The maximum level of emissions was found at 293.5 MHz with a quasi-peak value of 41.2 dBuV/m. The remaining marker represent the Peaks in the remainder of the transmit band. Regrettably the display table was not ‘turned off’ when the scan was saved, however, the market table shows the peak emissions. WLL Report 15412-01 REV 2 Page-15 of 23-
