Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the Federal Communication Commission (FCC) rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment causes harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by doing one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help.

Product R-Series Ground Conductivity Meter Standard(s) FCC KDB 447498:2015 Page 2 of 5 Report Issued: 7/6/2021 Report File #: 7169009616RF-000 © TÜV SÜD Canada Inc. This test report shall not be reproduced except in full, without written approval of TÜV SÜD Canada Inc. RF Exposure – FCC The device is a mobile device intended to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structure and the body of the user or nearby persons. The EUT contains a 9kHz transmitter and a modularly certified 2400 – 2483.5 MHz DTS transmitter. For the 9kHz transmitter, an inquiry was submitted to FCC and the limits for both E-field and H-field in KDB publication 680106 may be used to show compliance for the EUT. Radiofrequency Radiation Exposure Evaluation: Mobile Devices Mobile devices shall be evaluated for RF radiation exposure according to the provisions of FCC §2.1091 and the MPE guidelines identified in FCC §1.1310. As per FCC §1.1310 Table 1(B), the limit for Maximum Permissible Exposure (MPE) to radiofrequency electromagnetic fields for General Population/Uncontrolled Exposure in the frequency range of 300 MHz to 1.5 GHz is f/1500 mW/cm 2 and in the frequency range of 1.5GHz to 100GHz is 1.0 mW/cm 2 . Where f = frequency in MHz. The power density formula is given by: P d = (P out *G) / (4*pi*R 2 ) Where, P d = Power density in mW/cm 2 P out = Conducted output power to antenna in mW G = Numeric Antenna Gain Pi = 3.1416 R = Separation distance in cm Max power densities (Pd), for the Wi-Fi Module is shown below, as per the FCC approval grant.

This test report shall not be reproduced except in full, without written approval of TÜV SÜD Canada Inc. Supplementary Procedure for Assessing Compliance with Nerve Stimulation Exposure Limits Purpose Evaluation of RF Exposure test data for determining compliance of systems operating at frequencies below 100 kHz is provided on a case-by-case basis following an FCC KDB inquiry. An inquiry was submitted and the limits for both E-field and H-field in KDB publication 680106 may be used to show compliance for the EUT (R-Series Ground Conductivity Meter) Limit(s) and Method The limits applied are as per KDB 680106 Section 3 and as defined in SPR-002 Table 2. Whole Body/Torso/Head limits for general public exposure were applied as worst case. The method used is the Direct Measurement as detailed in SPR-002 section: 6.6.1.1 and KDB 680106 Section 3.a)(2). The minimum distance an operator will be from the EUT during normal operation would be more than 20cm. The measurements were maximized and done with the field probe 20cm away from the transmitter. Results The EUT passed the requirements. The EUT was checked along the roll angle to find the worst-case emission. The E- and H-field were measured with a field probe 20cm away from the transmitter at position 1 and 2 as shown in the diagram below and worst-case results were obtained at position 2. The results are indicated in the table below. Measured Field Limit Results Electric Field (V/m) 10.40 V/m peak 83.0 V/m r.m.s Pass Magnetic Field (A/m) 28.59 A/m peak 90.0 A/m r.m.s Pass Field Probe Position Diagram EUT 1 2 Tx 20cm Client Geosensors, Inc.
