General Information This report is prepared as a means of presenting test data to be used by a Telecom Certification Body in determination of whether this product is permitted for unlicensed dissemination to the general public according to the Innovation, Science, and Economic Development Canada and FCC Rules and Regulations for RF Devices Intentional Radiators. 1.1 Product Description The Equipment under Test (EUT) is the Radio Systems Corporation Yard Trainer 100 (YT-100) Model SDT54-16682 Transmitter. The EUT is a handheld transmitter used with a training collar that is designed to be lower cost entry point SportDog product. The design uses a 433.9MHz radio and can achieve distances of 100 meters 1.2 Characterization of Test Sample The sample used for testing was received by US Tech on July 13, 2018 in good operating condition. 1.3 Related Submittal(s)/Grant(s) The EUT is subject to the following FCC Equipment Authorizations: a) Certification of the transmitter. b) Verification as a class B digital device. 2. Tests and Measurements 2.1 Configuration of Tested System The Test sample was tested per ANSI C63.10:2013, American National Standard of Procedures for Compliance Testing of Unlicensed Wireless Devices to show compliance to CFR 47, Part 15.231. All measurements are peak unless stated otherwise. The video filter associated with the spectrum analyzer was set to 3 times the resolution bandwidth or off throughout the evaluation process. There were no interconnecting cables to manipulate in an attempt to maximize emissions; however, the physical position of the EUT was varied through the three mutually exclusive orthogonal planes in an attempt to maximize the emissions. The worse case position is the position used for final measurements and is gathered in this test report. A block diagram of the tested system is shown in Figure 1. Page 3 of 17

The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section. The Radio Systems Corporation, Model SDT54-16682incorporates the antennas detailed in Table 3. Table 3. Antenna Description REPORT TYPE OF TYPE OF MANUFACTURER MODEL REFERENCE ANTENNA CONNECTOR Permanently Radio Systems None monopole N/A attached and Corporation soldered 2.5 Modifications to Equipment No modifications were needed to bring the EUT into compliance with the FCC Part or IC RSS requirements. 2.6 Test Procedure The EUT was configured as shown in the following block diagram(s) and photograph(s). The sample was tested per ANSI C63.10:2013. Conducted and radiated emissions data were taken with the test receiver or spectrum analyzer's resolution bandwidth adjusted to 9 kHz and 120 kHz depending on the frequency range of testing, 150 kHz-30 MHz or 30 MHz to 1000 MHz, respectively. All measurements are peak unless stated otherwise. The video filter on the spectrum analyzer was OFF throughout the evaluation process. Interconnecting cables were manipulated as necessary to maximize emissions. The EUT was rotated 360 degrees with the turntable to maximize emissions. The physical position of the EUT was varied through the three mutually exclusive orthogonal planes in an attempt to maximize the emissions. The final setup description is found in the test section of this report. Page 6 of 17

Except as shown in paragraph (e) of this section, the intentional radiator is restricted to the transmission of a control signal such as those used with alarm systems, door openers, remote switches, etc. Continuous transmissions, voice, video and the radio control of toys are not permitted. Data is permitted to be sent with a control signal. The following conditions shall be met to comply with the provisions for this periodic operation: (1) A manually operated transmitter shall employ a switch that will automatically deactivate the transmitter within not more than 5 seconds of being released. The transmitter is not a manually operated transmitter. (2) A transmitter activated automatically shall cease transmission within 5 seconds after activation. The transmitter is classified as an automatically activated transmitter and the transmitter does comply with transmissions ceasing after 5 seconds. See Figure 2 below. (3) Periodic transmissions at regular predetermined intervals are not permitted. However, polling or supervision transmissions, including data, to determine system integrity of transmitters used in security or safety applications are allowed if the total duration of transmissions does not exceed more than two seconds per hour for each transmitter. There is no limit on the number of individual transmissions, provided the total transmission time does not exceed two seconds per hour. This does not apply; the transmitter does not have periodic transmissions at pre- determined intervals, and does not have polling or supervision transmissions to determine system integrity. Transmissions from the Clear Connect transmitter in this product are always initiated by a user initiated event, such as a button press on a product in the system or a user interaction in a smart-phone app to adjust the position of the light dimmer or window shade. (4) Intentional radiators which are employed for radio control purposes during emergencies involving fire, security, and safety of life, when activated to signal an alarm, may operate during the pendency of the alarm condition. This does not apply; the transmitter is not employed for radio control purposes during emergencies. (5) Transmission of set-up information for security systems may exceed the transmission duration limits in paragraphs (a)(1) and (a)(2) of this section, provided such transmissions are under the control of a professional installer and do not exceed ten seconds after a manually operated switch is released or a transmitter is activated automatically. Such set-up information may include data. This does not apply; the transmitter is not used for security systems. Page 8 of 17

The EUT emissions measurement was started by setting up the Antenna in the vertical orientation at a distance of 3 meters from the EUT and at a height of 1.0 meters above the ground. The EUT’s major axis was set normal to the direction of the measuring antenna. The Spectrum Analyzer (SA) displays were set to: Channel A free-running, Channel B to Max-Hold. Choose a frequency or frequency range and scan it at a coupled rate. When a signal is detected, raise and lower the antenna to maximize the signal. When the signal has been maximized, the antenna height is fixed the turn-table is rotated through 360 degrees to further maximize the signal. When all signals have been maximized for antenna height and direction, the EUT case is carefully maneuvered in each of the three mutually exclusive orthogonal planes while observing the same Max-hold/free-running SA display indication. When the EUT position is found that further maximizes the signal, record the antenna height, rotation orientation, EUT orthogonal position and signal strength on the data sheet for that particular frequency. Next, the measurement antenna is re-oriented to a Horizontal polarization at 1 meter height and the process described above is repeated. All signals within 6 dB of the limit are recorded. Finally, the collected data is input into the calculation spread sheet. The spread sheet is designed to calculate for the true value that is collected. The spread sheet takes into account the SA reading, the antenna correction factor, cable losses and duty cycle factors. See the data tables herein. Page 10 of 17

If average emissions measurements are employed, the provisions in 15.35 for averaging pulsed emissions and for limiting peak emissions were applied. Spurious and harmonics signals meet the requirements of the above table or the requirements of 15.209, whichever requirement permits higher field strength. Page 11 of 17

US Tech Test Report: FCC Part 15/IC RSS-210 Certification FCC ID: KE3-3003359 IC: 2721A-3003359 Test Report Number: 18-0186 Issue Date: August 23, 2018 Customer: Radio Systems Corporation Model: SDT54-16682 2.12 Bandwidth of Fundamental (CFR15.231(c), RSS-210, A.1.3) The bandwidth of the emission shall be no wider than 0.25% of the center frequency for devices operating above 70 MHz and below 900 MHz. Bandwidth is determined by those frequencies that are at least 20 dB down on either side of the center frequency of the pulse and as the 99% bandwidth. Bandwidth of Fundamental= 0.0025 x 433,920,000.00 = 1.0848 MHz The WORST CASE measured bandwidth is 159.295 kHz, well within the limit. See the figure below. Figure 3.
