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.

- 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 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 500 cm minimum clearance from the antenna while the system is operating.

- Antennas must be installed in accordance with FCC 27.50 and SRSP 517. For different gain antennas refer to the relevant rules and the local licensing authorities.

- 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. Confidential & Proprietary 7/47 If powered directly from the mains distribution system, it shall be used additional protection, such as 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

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

- Use of unauthorized antennas, cables, and/or coupling devices not conforming with ERP/EIRP Confidential & Proprietary 8/47 and/or indoor-only restrictions is prohibited.

- Home/ personal use are prohibited. UL/CUL: This equipment complies with UL and CUL 1950-1 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

- IC Booster warning label message should include WARNING: This is NOT a CONSUMER device. It is designed for installation by an installer approved by an ISED licensee. You MUST have an ISED LICENCE or the express consent of an ISED licensee to operate this device. Confidential & Proprietary 9/47 Section2 System configuration and Functions Confidential & Proprietary 10/47 2.1 HROU (High power Remote Optic Unit) HROU consists of two unit, one is HMRU(High power Main Remote Unit) and the other is HARU(High power Add-on Remote Unit). The biggest difference between HMRU and HARU is whether R-OPTIC module exist or not in the enclosure. HMRU receives TX optical signals from ODU and converts them into RF signals. The converted RF signals are amplified through High Power Amp in a corresponding HRDU band combined with UDCU, PAU and Cavity duplexer, and then radiated to the antenna port. When receiving RX signals through the antenna port, this unit filters out-of-band signals in a corresponding HRDU and sends the results to R-OPTIC to make electronic-optical conversion of them. After converted, the signals are sent to a upper device of ODU. HMRU can be equipped with up to four HRDUs (High Remote Drive Unit) and the module supports single band only. HARU receives TX RF signal from HMRU and amplifies through High Power Amp in a corresponding HRDU combined with UDCU, PAU and Cavity duplexer, and then radiated to the CU(Combining Unit) When receiving RX signals through the antenna port, HRDU filters out-of band signal in a corresponding HRDU and sends the results to MHRU through RF cable.

"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."
