The transmitter is a Base Station where access is controlled and only available to trained personnel. Please note that the internal photos are being asked to be confidential under the FCC guidelines that this is a non-consumer device (Base Station) and is inaccessible to the general public due to the location of the device and it is only serviceable by the licensee or his designated technicians. The user manual is being requested to be confidential under the FCC guidelines that the manual is very technical and is not provided to the general public. The user manual contains proprietary information required for trained installers to commission the base station. The user manual will be used by the licensee or his designated technicians only. Having the subject information easily available to competitors would negate the advantage we have achieved by developing this product. As a condition of sale Samsung(Grantee) requires an agreement with the buyer that internal photos and users manuals are proprietary material and held confidential. Samsung (Grantee) acknowledges that the requested internal photos and users manual(s) were filled as non-

confidential in the original application and understands that internal photos and users manual(s) were public records from the date of grant (grant date per FCC ID) to a date that the requested documents are made confidential. Samsung understands that the FCC has no obligation to remove internal photos and users manual(s) being provided publicly by any third-party organizations not affiliated with the FCC that obtained the information during the period that it was publicly available on the FCC Web Site.

Procedure to Connect System Cable Grounding Ground Cable Connection Power Cabling Hybrid(Power) Cable Connection Hybrid(Optical) Cable Connection External Interface Connection RET Cable Connection RF Cable Connection RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 38 Chapter 3 Connecting Cables Guidelines for Cable Connections The procedure for cable connections is as follows:

Figure 31. Cable Connection Procedure Cable Path Inspection Cable Cutting Cable Installation Connector Attachment When assembling the connector at the site Connector Assembly Cable Binding Identification Tag Attachment When cutting the cable after installation, make sure that the connector is disconnected. Installation of the cable with the connector connected to the system may cause contact failure or damage to the connector assembled to the system and the cable due to cable tension or the operators mistakes. The sequence of cable cutting and installation of the cable workflow can be changed depending on the field situation such as cutting after installing or installing after cutting. Cable Path Inspection When installing a cable that connects between the rectifier, Main Ground Bar

(MGB), and backhaul device, and so on within the system, the cable path, length and the cable installation method, and so on must be inspected. Follow these guidelines when inspecting the cabling path. A minimum cable length must be selected provided that it does not affect the cable installation and maintenance. RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 39 Chapter 3 Connecting Cables The cable must be placed in a location where it will not be damaged by external factors (power line, flooding, footpaths, and so on). In areas where the cable may be damaged by external factors, ensure that measures are taken to prevent damage to the cable (cable tray, ducts, flexible pipe, and so on). Cable Cutting Measure the exact distance, carefully checking the route, and cut the cable using a cutting tool. Follow these guidelines when cutting the cable. Cut the cable to the length determined in the Cable Path Inspection step. Use a dedicated cable cutting tool. Cut the cable at right angles. Be careful to keep the cable away from any moisture, iron, lead, dust, or other foreign material when cutting. Remove any foreign material attached to the cable using solvent and a brush. Cable Installation Cable installation involves running the cable along the cabling path to the target connector of the system or an auxiliary device after cable path inspection and cable cutting have been completed. Follow these guidelines when installing a cable:

Be careful not to damage the cable. If the cable is damaged, cut out the damaged section before installing, or replace the cable. Run the cable so that it is not tangled. In particular, when installing a cable from a horizontal section to a vertical section, be careful not to reverse the upper and lower lines of the cable. Always use the maximum curvature radius possible, and make sure that the minimum curvature radius specification is complied with. If the cable needs to be protected, use for example, a PVC channel, spiral sleeve, flexible pipe, cable rack, and so on. Install the DC power cable and data transmission cable away from the AC power cable to prevent electromagnetic induction. RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 40 Chapter 3 Connecting Cables Table 16. Recommended Minimum Allowed Cable bend Radius No Type Allowed Cable Bend Radius 1 2 Ground/Power Cable 8 times of the cable external diameter Optical Cable (indoor) Unloaded Condition (Installed)

Feeder Line (Flexible) 4.92 in.(125 mm) If the allowed cable bend radius is specified by the manufacturer, comply with the bend radius specified. Cable Binding Cable binding involves fixing and arranging an installed cable using binding thread, cable ties, binding wire, and ram clamps, and so on. Follow these guidelines when binding a cable. Be careful not to damage the cable during binding. Use appropriate cable binding tools according to the target location (indoor or outdoor, and so on) and the type of the cable (power supply cable, optical cable, feeder line, and so on). Do not let the cutting section of a cable tie and binding line, and so on be exposed to the outside. This may cause damage to cables or personal injury. Make sure that the cutting sections of cable ties and binding lines, and so on are not exposed to the outside. Cut off the remainder of the cable thread by leaving about 50 mm of extra length to prevent the knot from easily getting untied. If there is a danger that contact failure may occur in a connector connection due to tension, bind the cable at the closest location to the connector. Connector Attachment Connector attachment involves assembling a connector to an installed cable or to a device on the site. Follow these guidelines when attaching a connector. Make sure operator is fully aware of the connector assembly method before assembling a connector. Assemble the connector in accordance with its pin map. Each connector has a hook to prevent its core positions from being changed. RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 41 Chapter 3 Connecting Cables Check the corresponding grooves before connecting a connector to another connector. Use a heat shrink tube at a connector connection for cables that are installed outdoor, such as feeder lines, to prevent water leakage and corrosion from occurring at the part exposed to the outside. Connect each cable of the connector assembly in a straight line. Be careful when connecting a cable so that contact failure does not occur at a connector connection due to tension. Identification Tag Attachment Identification tag attachment involves attaching a marker cable tie, nameplate, and label, and so on to the both ends of a cable (connections to a connector) to identify its use and cabling path. Follow these guidelines when attaching an identification tag. When installing a cable outdoor, use relief engraving and coated labels, and so on to prevent the markings from being erased. Since the form and attachment method for identification tags are different for each provider, consult with the provider before attaching them. When connecting the cables, always connect the ground cable first. If worker contacts the equipment, connect a cable or perform maintenance without connecting the ground cable, the system can be damaged or a worker may be injured due to static electricity and short circuit. When performing cable work for the system, proceed with the ground work before any other work to prevent errors occurring due to static electricity and other reasons. When installing, take care not to overlap or tangle the cables; also, consider future expansion. Install the DC power cable and data transmission cable away from the AC power cable to prevent electromagnetic induction. Make sure the work is done by personnel properly trained for the cabling job.

- The Cable: Hybrid(Power) Cable, Hybrid(Optical) Cable RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 44 Chapter 3 Connecting Cables Grounding Grounding is the process of operating an electronic system (for example. power supplying system, communication system, and control system) stably from a lightning, transient-current, transient-voltage and electric noise and of preventing injury from electric shock. Ground equipment minimizes the electrical potential of the electronic device to that of the ground, which is zero electrical potential, so that it can prevent the device from occurring electrification. Connect the ground cable first. In cabling, the connection of cables without the connection to the ground cable may cause damage of the equipment or bodily injury to personnel. The purposes of the ground construction are as follows:

To prevent human life and the system from over-current, over-voltage, and lightning To provide a discharge path for surge voltage generated by lightning and power switch To protect the system from static electricity To eliminate or minimize the high-frequency potential in the system housing To provide a conductor for the balance and stability of high-frequency current To stabilize the potential of the circuit against the ground RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 45 Chapter 3 Connecting Cables Ground Cable Connection To connect the ground cable 1 Make sure that operator has the following items:

Figure 35. Power Equipment Elements Commercial Power AC Distributor Rectifier System AC DC Since power is applied to the system where the power cable is connected by manipulating the circuit breaker of the rectifier, be sure to check the rectifiers breaker is turned off (open) before connecting the power cable to the power connector. If the system is installed while the circuit breaker is on, the worker may be critically injured as soon as the cable is connected in the wrong way. Handling the power cable incorrectly may damage the rack or cause an electric short-circuit through the cable. Ensure the power switch on the rectifier or the system is turned off before handling the power. The fasteners for power cable must be tightly secured to prevent electrical accidents. The heat-resistant temperature of the power cable should be 90C or more. Install the power cable to the power port of the system by considering the radius of curvature of its cable specification and then cut the cable. If operator installs the cable after cutting, there may be length difference among the core wires at the end of the cable because of cable curvature. This may result in poor contact after the cable is connected to the power port. Install a circuit breaker to a rectifier (or power distributor) for the stable power. The capacity of circuit breaker is 20 A or 25A. (Use UL Listed circuit breakers.)

Connection Part of System External Interface Connector Antenna Measure all cables of section ~. The measured VSWR should be the specification value or less. If the VSWR exceeds the specification value, disassemble the connector and measure each section separately. If the VSWR value for minimum cable bend radius and length of RF cable is not applied, system may not work properly because RF signals cannot transmit or receive smoothly. So, the VSWR value for minimum cable bend radius and length of RF cable must be checked and applied. When measuring VSWR, if operator opens the antenna port when the transmission output is not completely off, a spike signal may flow into the reception path, which may cause damage to LNA. Make sure the transmission output is completely off when measuring VSWR. When RF cable connection integrated RET signal and DC power is applied using ANT0 port of RRU, RET cable should be installed separated from RF cable to RF Antenna. Depending on the supplier or manufacturer of antenna/arrestor the connector type may be different. Also, the detail specifications of a connector may be different depending on cable type even for the same connector type. Therefore, check the detail specifications of a connector before preparing parts. Ex) DIN Type-Male: for 1/2 in. Feeder line, for 7/8 in.

Bringing in Items Bring in items, taking care of the followings:

When carrying a system, fasten the system firmly to the transport vehicle or carrier to prevent a damage to the system for a vibration or shock. When carrying system, use a lift to prevent accidents. However, if the system must be carried by people, enough people are required to carry the system. Before moving the system, check the storage place for the system and remove obstacles in advance. While moving system, the system should not be shocked physically and damaged caused by dust, moisture, and static electricity. Unpacking Items The procedure to unpack items is as follows:

The packing items must be packed until they reach the installation place. The items are classified in accordance with each job specification and stored on a place that does not interfere with working. Unpacked systems must be installed immediately. If not installed immediately, the systems must be stored in the installation place temporarily. Unpack only external packing, leaving the internal packing in unpacked status. Unpack the inner packaging after each system is placed on its installation location. Scrap by-products (packaging waste) in accordance with the rule. Do not recycle the by-products. RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 12 Chapter 2 Installing System RRU Handling When transporting an RRU, hold a handle at the top of the RRU.

Procedure to Connect System Cable Grounding Ground Cable Connection Power Cabling Hybrid(Power) Cable Connection Hybrid(Optical) Cable Connection External Interface Connection RET Cable Connection RF Cable Connection RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 38 Chapter 3 Connecting Cables Guidelines for Cable Connections The procedure for cable connections is as follows:

Figure 31. Cable Connection Procedure Cable Path Inspection Cable Cutting Cable Installation Connector Attachment When assembling the connector at the site Connector Assembly Cable Binding Identification Tag Attachment When cutting the cable after installation, make sure that the connector is disconnected. Installation of the cable with the connector connected to the system may cause contact failure or damage to the connector assembled to the system and the cable due to cable tension or the operators mistakes. The sequence of cable cutting and installation of the cable workflow can be changed depending on the field situation such as cutting after installing or installing after cutting. Cable Path Inspection When installing a cable that connects between the rectifier, Main Ground Bar

(MGB), and backhaul device, and so on within the system, the cable path, length and the cable installation method, and so on must be inspected. Follow these guidelines when inspecting the cabling path. A minimum cable length must be selected provided that it does not affect the cable installation and maintenance. RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 39 Chapter 3 Connecting Cables The cable must be placed in a location where it will not be damaged by external factors (power line, flooding, footpaths, and so on). In areas where the cable may be damaged by external factors, ensure that measures are taken to prevent damage to the cable (cable tray, ducts, flexible pipe, and so on). Cable Cutting Measure the exact distance, carefully checking the route, and cut the cable using a cutting tool. Follow these guidelines when cutting the cable. Cut the cable to the length determined in the Cable Path Inspection step. Use a dedicated cable cutting tool. Cut the cable at right angles. Be careful to keep the cable away from any moisture, iron, lead, dust, or other foreign material when cutting. Remove any foreign material attached to the cable using solvent and a brush. Cable Installation Cable installation involves running the cable along the cabling path to the target connector of the system or an auxiliary device after cable path inspection and cable cutting have been completed. Follow these guidelines when installing a cable:

Be careful not to damage the cable. If the cable is damaged, cut out the damaged section before installing, or replace the cable. Run the cable so that it is not tangled. In particular, when installing a cable from a horizontal section to a vertical section, be careful not to reverse the upper and lower lines of the cable. Always use the maximum curvature radius possible, and make sure that the minimum curvature radius specification is complied with. If the cable needs to be protected, use for example, a PVC channel, spiral sleeve, flexible pipe, cable rack, and so on. Install the DC power cable and data transmission cable away from the AC power cable to prevent electromagnetic induction. RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 40 Chapter 3 Connecting Cables Table 16.

Feeder Line (Flexible) 4.92 in.(125 mm) If the allowed cable bend radius is specified by the manufacturer, comply with the bend radius specified. Cable Binding Cable binding involves fixing and arranging an installed cable using binding thread, cable ties, binding wire, and ram clamps, and so on. Follow these guidelines when binding a cable. Be careful not to damage the cable during binding. Use appropriate cable binding tools according to the target location (indoor or outdoor, and so on) and the type of the cable (power supply cable, optical cable, feeder line, and so on). Do not let the cutting section of a cable tie and binding line, and so on be exposed to the outside. This may cause damage to cables or personal injury. Make sure that the cutting sections of cable ties and binding lines, and so on are not exposed to the outside. Cut off the remainder of the cable thread by leaving about 50 mm of extra length to prevent the knot from easily getting untied. If there is a danger that contact failure may occur in a connector connection due to tension, bind the cable at the closest location to the connector. Connector Attachment Connector attachment involves assembling a connector to an installed cable or to a device on the site. Follow these guidelines when attaching a connector. Make sure operator is fully aware of the connector assembly method before assembling a connector. Assemble the connector in accordance with its pin map. Each connector has a hook to prevent its core positions from being changed. RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 41 Chapter 3 Connecting Cables Check the corresponding grooves before connecting a connector to another connector. Use a heat shrink tube at a connector connection for cables that are installed outdoor, such as feeder lines, to prevent water leakage and corrosion from occurring at the part exposed to the outside. Connect each cable of the connector assembly in a straight line. Be careful when connecting a cable so that contact failure does not occur at a connector connection due to tension. Identification Tag Attachment Identification tag attachment involves attaching a marker cable tie, nameplate, and label, and so on to the both ends of a cable (connections to a connector) to identify its use and cabling path. Follow these guidelines when attaching an identification tag. When installing a cable outdoor, use relief engraving and coated labels, and so on to prevent the markings from being erased. Since the form and attachment method for identification tags are different for each provider, consult with the provider before attaching them. When connecting the cables, always connect the ground cable first. If worker contacts the equipment, connect a cable or perform maintenance without connecting the ground cable, the system can be damaged or a worker may be injured due to static electricity and short circuit. When performing cable work for the system, proceed with the ground work before any other work to prevent errors occurring due to static electricity and other reasons. When installing, take care not to overlap or tangle the cables; also, consider future expansion. Install the DC power cable and data transmission cable away from the AC power cable to prevent electromagnetic induction. Make sure the work is done by personnel properly trained for the cabling job.

Ground equipment minimizes the electrical potential of the electronic device to that of the ground, which is zero electrical potential, so that it can prevent the device from occurring electrification. Connect the ground cable first. In cabling, the connection of cables without the connection to the ground cable may cause damage of the equipment or bodily injury to personnel. The purposes of the ground construction are as follows:

To prevent human life and the system from over-current, over-voltage, and lightning To provide a discharge path for surge voltage generated by lightning and power switch To protect the system from static electricity To eliminate or minimize the high-frequency potential in the system housing To provide a conductor for the balance and stability of high-frequency current To stabilize the potential of the circuit against the ground RFD01F Series Installation Manual v1.0 Samsung Proprietary and Confidential 45 Chapter 3 Connecting Cables Ground Cable Connection To connect the ground cable 1 Make sure that operator has the following items:

If the system is installed while the circuit breaker is on, the worker may be critically injured as soon as the cable is connected in the wrong way. Handling the power cable incorrectly may damage the rack or cause an electric short-circuit through the cable. Ensure the power switch on the rectifier or the system is turned off before handling the power. The fasteners for power cable must be tightly secured to prevent electrical accidents. The heat-resistant temperature of the power cable should be 90C or more. Install the power cable to the power port of the system by considering the radius of curvature of its cable specification and then cut the cable. If operator installs the cable after cutting, there may be length difference among the core wires at the end of the cable because of cable curvature. This may result in poor contact after the cable is connected to the power port. Install a circuit breaker to a rectifier (or power distributor) for the stable power. The capacity of circuit breaker is 20 A or 25A. (Use UL Listed circuit breakers.)

Connection Part of System External Interface Connector Antenna Measure all cables of section ~. The measured VSWR should be the specification value or less. If the VSWR exceeds the specification value, disassemble the connector and measure each section separately. If the VSWR value for minimum cable bend radius and length of RF cable is not applied, system may not work properly because RF signals cannot transmit or receive smoothly. So, the VSWR value for minimum cable bend radius and length of RF cable must be checked and applied. When measuring VSWR, if operator opens the antenna port when the transmission output is not completely off, a spike signal may flow into the reception path, which may cause damage to LNA. Make sure the transmission output is completely off when measuring VSWR. When RF cable connection integrated RET signal and DC power is applied using ANT0 port of RRU, RET cable should be installed separated from RF cable to RF Antenna. Depending on the supplier or manufacturer of antenna/arrestor the connector type may be different. Also, the detail specifications of a connector may be different depending on cable type even for the same connector type. Therefore, check the detail specifications of a connector before preparing parts. Ex) DIN Type-Male: for 1/2 in. Feeder line, for 7/8 in.
