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 50 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 5/19 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 shall be taken; and

- Access is through the use of a TOOL or lock and key, or other means of security, and is on trolled by the authority responsible for the location.

- Notice! Be careful not to touch the Heat-sink part due to high temperature.

- Signal booster warning label message should include as follows:

Confidential & Proprietary 6/19

- Certification FCC: This equipment complies with the applicable sections of Title 47 CFR Parts 15,22,24,27 and 90

- Use of unauthorized antennas, cables, and/or coupling devices not conforming with ERP/EIRP and/or indooronly restrictions is prohibited.

- Home/ personal use are prohibited. UL/CUL: This equipment complies with UL and CUL 62368-1 Standard for safety for information technology equipment,including electrical business equipment FDA/CDRH: This equipment uses a Class 1 LASER according to FDA/CDRH Rules.This product conforms to all applicable standards of 21 CFR Chapter 1, Subchaper J, Part 1040 FCC Part 15.105 statement This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. 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. RF Exposure Statement The antenna(s) must be installed such that a minimum separation distance of at least 35 cm is maintained between the radiator (antenna) and all persons at all times. This device must not be co-located or operating in conjunction with any other antenna or transmitter. Confidential & Proprietary 7/19 Section2 System configuration and Functions 2.1 eROU (edge Remote Optic Unit) eROU receives TX optical signals from eHUB and converts them into RF signals. The converted RF signal is radiated to the antenna port via the AMP and Multiplexer. When receiving RX signals through the antenna port, this unit filters out-of-band signals in a corresponding Multiplexer and sends the results to OPTIC to make electronic-optical conversion of them. After converted, the signals are sent to a upper device of eHUB. The eROU supports up to 4 bands. In addition, if band extension is required, another eROU can be added up to three using optical splitters and RF ports. However, the band expansion equipment will be developed in the future. And eROU is divided into an Internal product with an antenna and an External product without an antenna.. eROU cROU CASCADE_KIT External PSU aROU aROU External PSU Figure 1. eROU Configuration Diagram Confidential & Proprietary 8/19
