Any person involved in installation or service of the DAS should understand and follow these safety guidelines.

- Obey all general and regional 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.

- 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.

- When working with units outdoors, make sure to securely fasten the door or cover in an open position to prevent the door from slamming shut in windy conditions.

- Use this unit only for the purpose specified by the manufacturer. Do not modify or fit any spare parts that 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 300cm 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.

- 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.

- Round terminals located on the side of a 1 mm2 (16 AWG) or more wires Using permanently connected to earth.(green/yellow color)

- The following notice: "The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device."

-

Part 27.50 Antennas must be installed in accordance with FCC 27.50 and SRSP 518. With 17dBi gain antennas the height of the antenna above average terrain (HAAT) must not exceed 737m. For different gain antennas refer to the relevant rules.

- Prior to equipment use the service must be registered with the FCC. This can be done through the FCCs website at https://signalboosters.fcc.gov/signal-boosters/.

- 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 Confidential & Proprietary 7/39

- 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.

As a distributed antenna system, it provides analog and digital phone systems that are served in multiple bands through one antenna. The system covers general public institutions and private facilities. Shopping malls Hotels Campus areas Airports Clinics Multi-use stadiums, convention centers, etc. Subways The system helps improve in-building radio environments in poor condition and make better poor RSSI and Ec/Io. By providing communication services at every corner of buildings, the system enables users to make a call at any site of buildings. The system uses both analog (AMPS) and digital (TDMA, CDMA and WCDMA) methods. The HERCULES system supports communication standards and public interface protocols in worldwide use. Frequencies: 700MHz , 700MHz_MIMO , 850MHz , 1900MHz , 2100MHz , 2100MHz_MIMO etc. Voice protocols: AMPS,TDMA, CDMA,GSM,IDEN, etc. Data protocols: EDGE,GPRS,WCDMA,CDMA2000,Paging, LTE etc. HERCULES is in modular structure per frequency. To provide desired frequency in a building, all you need to do is to insert a corresponding frequency module into each unit. As it delivers multiple signals with one optical cable, the system, in one-body type, does not require additional facilities whenever new frequency is added. The system is featured with the following:

Support fiber-optic ports up to 60 Flexibility & Scalability Clustering multiple-buildings (campus) as one coverage Modular structures Modular frequency upgrade Plug-in type module Multi-Band, Multi Operator Confidential & Proprietary 10/39 Signals with a plurality of service provider transmit simultaneously Support multi-operator in a band Low OPEX / CAPEX Compact design Upgradable design Easy installation and maintenance 2.2 HERCULES Hercules is one of series of Alliance DAS and has 5W composite output power every band. RDU that is integrated on package with Duplexer, Power amplifier and RF unit can be mounted up to 6 in the enclosure. Hercules transports signals that multiple operators and multiple technologies are moved at a same time from Base station to a remote location over the same fiber. It is available in single and multi-band configuration supporting 700M, 700M MIMO , 850M , 800I , 900I , 700P , 800P , 1700/2100M, 1700/2100MHz MIMO , 1900M in parallel. It has been specifically tested under a various air interfaces such as iDEN, GSM, CDMA2000, EV-DO, WCDMA, LTE , ect. Furthermore, there is reserved RDU slot to support 2500LTE in the future And RDU slot is also possible to replace the desired frequency Band.

We have made a change to our User Manual for the following FCC IDs:

W6UHM80I85C W6UHM700L W6UHM700LM W6UHM850C W6UHM1900P W6UHMAWS1 W6UHMAWS1M The following verbiage was removed:

"The Manufacturer's rated output power of this equipment is for single carrier operations. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. This verbiage was removed due to translation error from Korean to English. The statement is incorrect. No replacement verbiage is required.
