Any person involved in installation or service of the DAS should understand and follow these safety guidelines.” - Obey all general and regional installation and safety regulations relating to work on high voltage installations, as well as regulations covering correct use of tools and personal protective equipment. - The power supply unit in repeaters contains dangerous voltage level, which can cause electric shock. Switch the mains off prior to any work in such a repeater. Any local regulations are to be followed when servicing repeaters. - eROU equipment is exclusive to the indoor. - Use this unit only for the purpose specified by the manufacturer. Do not carry out any modifications or fit any spare parts which are not sold or recommended by the manufacturer. This could cause fires, electric shock or other injuries. - Any DAS system or Fiber BDA will generate radio (RF) signals and continuously emit RF energy. Avoid prolonged exposure to the antennas. SOLiD recommends maintaining a 70 cm minimum clearance from the antenna while the system is operating. - Do not operate this unit on or close to flammable materials, as the unit may reach high temperatures due to power dissipation. - Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives on the DAS equipment. Alcohol may be used to clean fiber optic cabling ends and connectors. - To prevent electrical shock, switch the main power supply off prior to working with the DAS System or Fiber BDA. Never install or use electrical equipment in a wet location or during a lightning storm. - Do not look into the ends of any optical fiber or directly into the optical transceiver of any digital unit. Use an optical spectrum analyzer to verify active fibers. Place a protective cap over any radiating transceiver or optical fiber connector to avoid the potential of radiation exposure. - Allow sufficient fiber length to permit routing without severe bends. - For pluggable equipment, make sure to install the socket outlet near the equipment so that it is easily accessible. - A readily accessible disconnect device shall be incorporated external to the equipment. - This power of this system shall be supplied through wiring installed in a normal building. If powered directly from the mains distribution system, it shall be used additional protection, such as Confidential & Proprietary 6/17 overvoltage protection device - Only 50 ohm rated antennas, cables and passive equipment shall be used with this remote. Any equipment attached to this device not meeting this standard may cause degradation and unwanted signals in the bi-directional system. All components connected to this device must operate in the frequency range of this device. - Only 50 ohm rated antennas, cables and passive components operating from 150 - 3 GHz shall be used with this device. - The head end unit must always be connected to the Base Station using a direct cabled connection. This system has not been approved for use with a wireless connection via server antenna to the base station. - Access can only be gained by SERVICE PERSONS or by USERS who have been instructed about the reasons for the restrictions applied to the location and about any precautions that shal…

TEST INFORMATION FCC Rule Parts Part 2, Part 22, Part 27, Part 90 Measurement Standards KDB 935210 D05 v01r04, ANSI C63.26-2015 Test Location HCT CO., LTD. 74, Seoicheon-ro 578beon-gil, Majang-myeon, Icheon-si, Gyeonggi-do, 17383, Rep. of KOREA Report No. HCT-RF-2102-FC008 F-TP22-03 (Rev. 03) Page 6 of 171 2. FACILITIES AND ACCREDITATIONS 2.1. FACILITIES The SAC(Semi-Anechoic Chamber) and conducted measurement facility used to collect the radiated data are located at the 74, Seoicheon-ro 578beon-gil, Majang-myeon, Icheon-si, Gyeonggi-do, 17383, Rep. of KOREA. The site is constructed in conformance with the requirements of ANSI C63.4 (Version: 2014) and CISPR Publication 22. Detailed description of test facility was submitted to the Commission and accepted dated April 02, 2018 (Registration Number: KR0032). 2.2. EQUIPMENT Radiated emissions are measured with one or more of the following types of linearly polarized antennas: tuned dipole, bi-conical, log periodic, bi-log, and/or ridged waveguide, horn. Spectrum analyzers with pre-selectors and quasi-peak detectors are used to perform radiated measurements. Calibrated wideband preamplifiers, coaxial cables, and coaxial attenuators are also used for making measurements. All receiving equipment conforms to CISPR Publication 16-1, ᄲRadio Interference Measuring Apparatus and Measurement Methods.ᄶ Report No. HCT-RF-2102-FC008 F-TP22-03 (Rev. 03) Page 7 of 171 3. TEST SPECIFICATIONS 3.1. STANDARDS The following tests were conducted on a sample of the equipment for the purpose of demonstrating compliance with FCC Part 2, Part 22, Part 27, Part 90. Description Reference Results AGC threshold KDB 935210 D05 v01r04 3.2 Compliant Out-of-band rejection KDB 935210 D05 v01r04 3.3 Compliant Input-versus-output signal comparison §2.1049 Compliant Input/output power and amplifier/booster gain §2.1046, §22.913, §27.50(b), (c), §90.542, §90.635 Compliant Out-of-band/out-of-block emissions and spurious emissions §2.1051, §22.917, §27.53(c), (f), (g), §90.543 §90.691 Compliant Spurious emissions radiated §2.1053 Compliant Report No. HCT-RF-2102-FC008 F-TP22-03 (Rev. 03) Page 8 of 171 3.2. ADDITIONAL DESCRIPTIONS ABOUT TEST Except for the following cases, EUT was tested under normal operating conditions. : Out-of-band rejection test requires maximum gain condition without AGC. The test was generally based on the method of KDB 935210 D05 v01r04 and only followed ANSI C63.26-2015 if there was no test method in KDB standard. EUT was tested with following modulated signals provide by applicant.
