Page 8 of 30 Report No. : OT-18N-RWD-040 5. SYSTEM TEST CONFIGURATION 5.1 Justification This device was configured for testing in a typical way as a normal customer is supposed to be used. During the test, the following components were installed inside of the EUT. DEVICE TYPE MANUFACTURER MODEL/PART NUMBER FCC ID MAIN BOARD LG Innotek Co., Ltd. ESL TAG 3.7E Rev0.2 N/A BATTERY N/A N/A N/A 5.2 Peripheral equipment Defined as equipment needed for correct operation of the EUT, but not considered as tested: None 5.3 Mode of operation during the test -. For the testing, software used to control the EUT for staying in continuous transmitting is programmed. For final testing, the EUT was set at 2 405 MHz, 2 440 MHz, and 2 480 MHz to get a maximum emission levels from the EUT. The EUT was moved throughout the XY, XZ, and YZ planes and the worst case is “XZ” axis, but the worst data was recorded in this report. -. Equipment with two diversity antennas operating in switched diversity mode by which at any moment in time only one antenna is used and the worst case is Antenna 0 the worst data was recorded in this report. It should not be reproduced except in full, without the written approval of ONETECH Corp.

Page 9 of 30 Report No. : OT-18N-RWD-040 5.4 Configuration of Test System Line Conducted Test: It is not need to test this requirement, because the EUT shall be operated by DC battery. Radiated Emission Test: Preliminary radiated emissions test were conducted using the procedure in ANSI C63.10: 2013 to determine the worse operating conditions. Final radiated emission tests were conducted at 3 meter Semi Anechoic Chamber. The turntable was rotated through 360 degrees and the EUT was tested by positioned three orthogonal planes to obtain the highest reading on the field strength meter. Once maximum reading was determined, the search antenna was raised and lowered in both vertical and horizontal polarization. 5.5 Antenna Requirement For intentional device, according to section 15.203, an intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. Antenna Construction: The antenna of the EUT is a PCB Antenna on the main board in the EUT, so no consideration of replacement by the user.

EUT Spectrum analyzer 9.3 Test set-up for radiated measurement The radiated emissions measurements were performed on the 3 m semi anechoic chamber. The EUT was placed on turntable approximately 1.5 m above the ground plane. The frequency spectrum from 30 MHz to 26.5 GHz was scanned and maximum emission levels at each frequency recorded. The system was rotated 360°, and the antenna was varied in the height between 1.0 m and 4.0 m in order to determine the maximum emission levels.

RADIATED EMISSION TEST 11.1 Operating environment Temperature : 24.3 °C Relative humidity : 43.9 % R.H. 11.2 Test set-up The radiated emissions measurements were on the 3 m semi anechoic chamber. The EUT and other support equipment were placed on a non-conductive turntable above the ground plane. The interconnecting cables from outside test site were inserted into ferrite clamps at the point where the cables reach the turntable. The frequency spectrum from 30 MHz to 26.5 GHz was scanned and emission levels maximized at each frequency recorded. The system was rotated 360°, and the antenna was varied in height between 1.0 m and 4.0 m in order to determine the maximum emission levels. This procedure was performed for both horizontal and vertical polarization of the receiving antenna. 11.3 Test equipment used Model Number Manufacturer Description Serial Number Last Cal. - FSV40 Rohde & Schwarz Signal Analyzer 101009 Mar. 14, 2018 (1Y) - ESU Rohde & Schwarz EMI Test Receiver 100261 Mar. 29, 2018 (1Y) - 310N Sonoma Instrument Pre-Amplifier 312544 Mar. 28, 2018 (1Y) - BBV9718 Schwarzbeck Amplifier 310 Mar. 30, 2018 (1Y) - DT3000-3t Innco System Turn Table DT3000/093 N/A - MA-4000XPET Innco System Antenna Master MA4000/509 N/A - VULB9163 Schwarzbeck TRILOG Broadband Antenna 9163-419 Aug. 09, 2018 (2Y) - BBHA9120D Schwarzbeck Horn Antenna BBHA9120D295 Aug. 16, 2017 (2Y) - BBHA9170 Schwarzbeck Horn Antenna BBHA9170179 Jul. 28, 2017 (2Y) All test equipment used is calibrated on a regular basis.
