These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. FCC Part 15.21 statement Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. Home/ personal use are prohibited Use of unauthorized antennas, cables, and/or coupling devices not conforming with ERP/EIRP and/or indooronly restrictions is prohibited 2018 GS Instech Co., Ltd. All rights reserved. 9 Version 0.1 Date May 11, 2018 Page 10/ 42 Title USER MANUAL RF Radiation Exposure Prepared by Reviewed by Approved by This equipment complies with RF radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. RF exposure will be addressed at time of installation and the use of higher gain antennas may require larger separation distances. Antenna installation Antennas must be installed in accordance with FCC 27.50, 24. The height of the antenna above average terrain (HAAT) must not exceed limit in the following table.

User may select frequency band according to the site peculiarities. After receiving a weak signal from Donor antenna or BTS directly, the EZD-LICPA23 sends downlink signal to EZS-

LICPA30 using DOU (Donor Optic Unit). DOU supports the translation of RF signal to Optic signal for connecting EZS-LICPA30 through the fiber optic cable. And then Uplink Signal that received from EZS-LICPA30 amplify, is send to the Base station via Donor Antenna or is connected to BTS directly.

This transmitter operates as a remote unit as part of a system along with base station interface unit as described in this filing, and excluding any other devices connected to the (uplink) transmit output terminal of the base station interface unit. This application covers only the system configuration with base interface unit connected to a base station RF port in the uplink transmit path; operations of this remote unit if any in a system with base interface unit connected to antenna or amplifier for uplink transmissions require separate equipment authorization. This device is authorized to operate only as part of a distributed-antenna booster system installed in buildings. This filing has compliance demonstration information and test data only for SISO (single-input single-output) booster system configurations; additional equipment authorization is required to allow this device to be used in MIMO (multiple-input multiple-output) industrial booster systems. Users and installers must be provided with appropriate antenna installation instructions and transmitter operating conditions, including antenna co-location requirements of Sec. 1.1307(b)(3), for satisfying RF exposure compliance. RF exposure will be addressed at time of installation and the use of higher gain antennas may require larger separation distances.
