It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Prior to handling, shipping, and servicing equipment, always put on a conductive wrist strap connected to a grounding device to discharge any accumulated static charges. All RFN FRUs ship with a disposable anti-static wrist strap. 10 CONFIDENTIAL AND PROPRIETARY TRADE SECRET INFORMATION RadioFrame Networks, Inc. MC-Series High-Power System 998--01 Rev X1 Introduction Warning!

Use extreme caution when wearing a conductive wrist strap near sources of high voltage. The low impedance provided by the wrist strap also increases the danger of lethal shock should accidental contact with high voltage sources occur. Place FRUs only on an anti-static mat when removed from the system. The conductive surface must be connected to ground through 100 k. Do not use non-conductive material for packaging FRUs for shipment or storage. Wrap all FRUs with anti-static (conductive) material. Replacement FRUs shipped from the factory are packaged in a conductive material. If possible, retain all original packing material for future use. 1.2.2 Safety Warnings Warning!

The MC-Series High Power system is a 14 CONFIDENTIAL AND PROPRIETARY TRADE SECRET INFORMATION RadioFrame Networks, Inc. MC-Series High-Power System 998--01 Rev X1 System Definition stand-alone microcell base transceiver station (BTS) in the integrated Dispatch Enhanced Network (iDEN) that simultaneously supports the 800E and 900 MHz bands with the necessary Tx amplification to achieve +36 dBm per carrier. The three-sector configuration supplies twelve full-duplex iDEN carriers per sector, or the equivalent of up to 36 Base Radios (BRs) per site. The MC-Series High Power system supports two-branch receive diversity. The system interfaces with the Mobile Switching Office (MSO) via a standard T1 interface, which also provides the Operations and Maintenance Center (OMC) with alarm information and enables the OMC to remotely control and configure system operations via a standard site datafill. Operation of an MC-Series High Power system requires the use of Multi-channel RadioBlade (MCRB) transceivers. The MCRB duplicates the RF functions of up to 6 simultaneously operational iDEN radio transceivers, supporting six corresponding Transmit (Tx) Receive (Rx) channel pairs with full-duplex operation. In the case of MCRBs used for diversity, the transmitter is not utilized. The MC-Series high power system is shipped ready to install and configure. The system is enclosed in a single 19 equipment cabinet containing all RadioFrame Networks equipment as well as the two required iSC3s and the required EAS. The customer provides the required CSU and is responsible for T1 connectivity, datafill (network provisioning), antenna system, GPS (as required by iSC), electrical supply, any needed additional environmental cooling, and the necessary permitting.

The MCRB can operate in either the 800E or the 900 MHz band as configured by system software. RadioFrame Networks, Inc. CONFIDENTIAL AND PROPRIETARY 25 System Definition MC-Series High-Power System 998--01 Rev X1 Figure 18 MCRB Label Position 2.2.4.3 Combined RadioBlade Transceivers in an RBS The MCRB allows up to 6 BRs to be assigned to a single physical RadioBlade transceiver with a requirement applied that all carriers need to be within the same 1.25 MHz band. Because of this requirement, all frequencies need to be known prior to the programming of the MCRB. To accommodate this, all BRs set up in the iDEN configuration page will register with the network to get assigned frequencies. Once the frequencies are known, and the available HW resources are known, the carriers are assigned to the MCRBs and single-channel RadioBlade transceivers by the following rules:

1) Any 900 MHz BRs will be assigned to an MCRB. 2) The largest group of carriers which fall within the 1.25 MHz band is assigned to the MCRB if one is available. (Note: This process repeats until there are no remaining unassigned MCRBs.) 3) Any carriers that remain unassigned are assigned to single-channel RadioBlade transceivers. 4) 5) If any carriers are still unassigned, an alarm is sent to the OMC. If any MCRBs or single-channel RadioBlade transceivers are unassigned, they become standby blades. 2.2.5 High Power Dual-Band RF Shelf The MC-Series system provides one RF shelf per sector. The RF shelf contains amplifiers, filters, combiners, redundant DC-DC converters and fans to provide cooling to the power amplifiers (PAs). The transmit chain includes a software-controlled variable attenuator for adjusting the Tx power output at the top of the cabinet, a multi-channel linear power amplifier (PA), a band 26 CONFIDENTIAL AND PROPRIETARY TRADE SECRET INFORMATION RadioFrame Networks, Inc. MC-Series High-Power System 998--01 Rev X1 System Definition pass filter and a sampling port. The Tx sampling port provides approximately top of the rack (TOR) minus 20 dB output power. The Tx power output at the top of the rack can be varied by changing the datafill. The PA is sized to allow sufficient linearity and gain such that a minimum of +29 dBm per carrier (up to 12 carriers) can be achieved at the top of the rack. The sampling port signal is brought out to the front of the RF shelf to provide monitoring and testing of the transmit path. The receive path contains a band pass filter, low noise amplifier (LNA) and a sampling port. As with the Tx sampling port, the Rx sampling port is brought out to the front panel of the RF shelf. The Rx sampling port provides approximately top of the rack (TOR) minus 20 dB output power.

MC-Series High-Power System 998--01 Rev X1 ManagementDatafill, Configuration and Optimization 6 ManagementDatafill, Configuration and Optimization This section describes configuration techniques that affect the behavior of the MC-Series High-Power system. Section 6.1 covers the datafill parameters as they differ from the Motorola EBTS. Section 6.2 covers configuration options using System Manager, with sections 6.2.1 and 6.2.2 introducing basic operations and 6.2.3 presenting optimization procedures. 6.1 Datafill The MC-Series High-Power system is designed for compatibility with the Motorola EBRC and QUAD Base Radios (BRs). However, due to architecture differences between the two systems, not all datafill parameters apply equally to the MC-Series High-Power system. This section describes only those datafill parameters that need to be taken into consideration when used with the MC-Series High-Power system. Any datafill parameter not described here can be assumed to behave identically to the Motorola EBTS. This section includes:

6.1.1 Parameters that RFN does not support 6.1.2 Parameters that have no effect on the MC-Series High-Power system 6.1.3 Parameters that RFN supports, but which need to be setup differently from the typical setup for a Motorola BR 6.1.1 Unsupported Datafill Parameters The following datafill parameters are currently not supported. 6.1.1.1 steThresholdMode The Slot Timing Error Threshold Mode parameter has three different purposes:

Setting to zero allows the EBTS to automatically determine the STE threshold based on history of inbound transmissions. Setting to maximum value of 250 essentially disables the use of STE filtering. A manual override exists by setting the parameter in the range of 1 to 249. The default value is set to 250. This datafill parameter will be supported in the MC-Series High-Power system starting with 15.0 releases of System Manager software. 6.1.1.2 brPwrReducModeAcg The BR Power Reduction parameter is used to enable/disable the Power Reduction feature on a per-BR basis. The default value is set to 'ON' and it is on-line changeable. This feature will be supported in the MC-Series High-Power system starting with 15.0 releases of System Manager software. 6.1.2 Parameters that Do Not Apply to the MC-Series High-Power System The following parameters have no effect on the MC-Series High-Power system. There is no functional equivalent in the MC-Series High-Power system, and as such the parameters can be ignored. RadioFrame Networks, Inc. CONFIDENTIAL AND PROPRIETARY 57 ManagementDatafill, Configuration and Optimization MC-Series High-Power System 998--01 Rev X1 6.1.2.1 combinerType This parameter specifies the type of combiner used to connect the cells Base Radios to the antenna. The options are hybrid and cavity. The MC-Series High-Power system is similar to a cavity type combiner physically but it does not have the same frequency limitations as the cavity combiner that this parameter is used for. 6.1.3 Recommended Datafill Parameters 6.1.3.1 6.1.3.2 6.1.4 6.1.4.1 The following parameters need to be set differently than what is currently set with Motorola BR. These settings are not required but recommended for best operation. PCC The power control constant is broadcast on the BCCH and is used by the MS to calculate a target value for its transmit power. For Indoor Pico and Micro-Cell applications this value will vary depending upon the RF environment (i.e., if used outdoors the value will be quite different from an indoor scenario). For the MC-Series High-Power system, the setting of this parameter depends on what is connected between the MC-Series High-

Power system and the antenna. The default value should be calculated in accordance with Motorola guidance detailed in the Datafill Parameter Guide. It should be noted that in cases in which the Mobile subscribers are near the antenna source (downlink limited), the handsets could transmit at a much lower level than is the case with a Macro site. Lowering this parameter forces the mobile to operate at fairly low Tx level thus conserving battery life. In cases where the MC-Series High-Power system is connected to a DAS, the gains and losses of the paths should be taken into consideration. Additionally the level of uplink interference should be considered when determining this value. Pto (transmit power) The Cells outbound transmit power referenced at the output of the RF Distribution System Antenna Port. It is used as a reference point value when computing the link budget of the system. RFN recommends that the value of this parameter be set appropriate to the TOR output power, which is determined by the defaultTxPower parameter (see below). rxTxGain = 0 This parameter is the difference in gain between the receiver and transmit antenna paths expressed in dB. The MC-Series High-Power system does not use this parameter directly. defaultTxPower Note: Refer to release notes for range information. This is the average output power of the PA, measured at the RF connector of the BR. For the MC-Series High-Power system, this parameter can be used to adjust the output power of the system. The gain at the shelf is fixed and cannot be altered as was the case with the 800-only RF Shelf. The MC-Series High-Power system has a different range of output levels than a standard Motorola EBTS, and as such, these values will map to a different set of actual Tx output power levels. (The correspondence is shown in Table 16 in section 2.5.8.3 .) The nominal maximum Tx power at the top of the rack with a maximum variation of 2 dB is +29 dBm. The dynamic range is 11 dB. 58 CONFIDENTIAL AND PROPRIETARY TRADE SECRET INFORMATION RadioFrame Networks, Inc.

Depending on the severity, alarms are sent to the OMC via the iSC-3. The Alarms/Events Reference Guide, included on the MC-Series CD and available on the RadioFrame Networks website, lists the alarms by ID code. All alarms passed to the OMC use the Sprint Nextel Alarm Code 35009, which uses the event description Unable to key BR. 7.5.1 Viewing System Manager Alarms 1 Select the Alarms tab in System Manager to display the Active Alarm Manager. The Alarm Log displays active (un-cleared) alarms listed by date and time, and the Alarm Details window displays information about a single selected alarm (see Figure 50). A summary at the top of the page lists the current number of Critical, Major, Minor, and Warning alarms. Alarms that are no longer active are moved to the Alarm History Manager. Note:

Non-alarm events are displayed in the Events Log. The initial Events Log lists all the alarms generated by RFS components. You can view a smaller list by selecting one of the Show links at the bottom of the page. Clicking the first link with a value of 20 in the box displays the first 20 alarms.

TS/BR 7.5.3 System Manager Alarms The document Alarms/Events Reference Guide lists MC-Series system alarms numerically by alarm ID (0x01, 0x02, etc.). MC-Series alarms are based on the X.733 conventions for telecommunications equipment. The alarms are grouped by service: either asp for platform faults or iden for iden application faults. The cause field contains the X.733 cause type. System reaction describes the action taken by the system as a result of this alarm, and repair actions provides details on what corrective action should be taken as a result of this alarm. The Alarm details on the active alarm manager page of System Manager provides additional information with respect to the board, slot number, MAC address and equipment type. 7.6 RadioBlade Transceiver Alarm Handling The iDEN RadioBlade transceivers track various faults and reports to the RadioBlade controller. These faults are monitored, and if the rate at which these faults occur surpasses a threshold, the RadioBlade transceiver (blade) is locked. The blade will generate these faults as the result of normal actions such as re-syncing the blade, locking and unlocking the blade and locking and unlocking the BR. For these reasons, only if the blade continues to generate these faults under normal operating circumstances is an alarm generated. The RadioBlade transceiver tracks the faults listed in Table 28. Table 28 Faults Tracked by the Transceiver Fault PLL1 Errors PLL2 Errors PLL3 Errors Tx Underrun Description The Phase Lock Loop #1 went out of lock. The Phase Lock Loop #2 went out of lock. The Phase Lock Loop #3 went out of lock. RadioBlade transceiver did not receive a packet in time to transmit. RadioFrame Networks, Inc.

Sample buffer overflowed. Tx Overflow Rx OverFlow Slot mismatch Received packets were not consecutive. CRC errors Received Ethernet packets had CRC errors. If a RadioBlade transceiver generates enough errors such that it crosses the Bounce and Duration threshold for that particular error, an alarm will be generated. This alarm will also cause the RadioBlade Locking Policy to lock that RadioBlade transceiver. Table 29 lists the fault count and fault period for an alarm to be generated. Table 29 RadioBlade Transceiver Fault Thresholds for Alarm Generation Alarm Bounce Threshold

(counts) Duration Threshold

(minutes) PLL 1 PLL 2 PLL 3 Tx Underrun Tx Overflow Rx Overflow Slot Mismatch CRC Errors Packet Size Errors 75 75 50 40 40 40 40 20 20 12 12 12 12 12 12 12 12 12 In addition to the above-mentioned errors, if the system loses communication with a RadioBlade transceiver or is unable to read the EEPROM from the blade, then that blade is put into an error state and if a standby blade is available it will switch over automatically. 7.6.1 RadioBlade Locking Policy The RadioBlade locking policy defines the actions taken by the system when a determination is made that a RadioBlade transceiver should no longer be allowed to remain active. This could be the result of an alarm, insertion, removal or intervention (the user specifically locking the RadioBlade transceiver). In general, the policy is that if a blade is taken out of service and a standby RadioBlade transceiver is available, then the standby RadioBlade transceiver will go into service. If no standby RadioBlade transceiver is available then the associated BR(s) will be locked.

(For the Multi-Channel RadioBlade transceiver, the locking event locks all carriers.) The RadioBlade locking policy is enabled by default and in effect at all times. 7.6.1.1 Standby Blade A Standby Blade is an extra RadioBlade transceiver that is installed in the system but does not have a configured BR with which to register. To setup Standby Blades, make sure that there are more RadioBlade transceivers for each RBS Group than Base Radios configured in the iDEN configuration page. 82 CONFIDENTIAL AND PROPRIETARY TRADE SECRET INFORMATION RadioFrame Networks, Inc. MC-Series High-Power System 998--01 Rev X1 Scheduled and Unscheduled Maintenance 7.6.1.2 In all the conditions described below, if RadioBlade transceivers are present in the system that are in the hot-standby state, then locking the RadioBlade transceiver (due to alarms, removal of a RadioBlade transceiver or administratively locking RadioBlade transceivers) will result in the hot Standby Blade transceiver being assigned to the BR that de-registered the locked RadioBlade transceiver. Locking Policy for RadioBlade Transceiver with Errors If the RadioBlade transceiver generates enough faults such that it crosses the Bounce and Duration threshold for that particular error, an alarm will be generated. The RadioBlade controller then notifies the associated BR, which then locks the RadioBlade transceiver. This will result in disabling the BR. If there is a faulty RadioBlade transceiver in the system (generating error alarms), it is prevented from coming up after a commanded reset/system reset, but the operator could manually unlock the RadioBlade transceiver, at which point the RadioBlade transceiver would be assigned to a BR. (This would not prevent the system from locking it again if an excessive error condition recurs). 7.6.1.3 Removal of RadioBlade Transceiver When a RadioBlade transceiver is physically removed, an event is generated in the System Manager Event Log notifying the user about the RadioBlade transceiver removal. The RadioBlade controller will then de-register the RadioBlade transceiver from the BR(s), which will result in locking the BR(s). A RadioBlade transceiver Insert event is generated when the RadioBlade transceiver is inserted into the system. 7.6.1.4 Administrative Locking of a RadioBlade Transceiver By definition, administrative locking of a RadioBlade transceiver is in effect if the RadioBlade transceiver lock icon on the RadioBlade Transceiver Status page is changed to locked. The Multi-Channel RadioBlade transceiver is treated as a unit (single RBID) with respect to administrative locking. The following rules apply to locking a RadioBlade transceiver. The BR(s) associated with the administratively locked RadioBlade transceiver will go into a Disabled state. Only that RadioBlade transceiver will lock, and its icon will change to locked. If an administratively locked RadioBlade transceiver is replaced, the new RadioBlade transceiver will be considered unlocked upon insertion. (Administrative locking applies to a particular RadioBlade transceiver and not to a particular RBS Slot). Upon unlocking an administratively locked RadioBlade transceiver, the BR that was previously disabled due to the locked state will go into the enabled state. The lock policy will be preserved through a system reset. Locking of the RadioBlade transceiver will also be preserved through a system reset. Locking of RadioBlade transceivers in the disabled state will not be preserved through a system reset. However, after a system reset, those blades that were originally in the disabled state due to the RadioFrame Networks, Inc. CONFIDENTIAL AND PROPRIETARY 83 Scheduled and Unscheduled Maintenance MC-Series High-Power System 998--01 Rev X1 effects of a) the locked RadioBlade transceiver and b) the locking policy will likely return to the disabled state. The RadioBlade Control page of System Manager has a Lock All / Unlock All feature. Refer to Figure 51. Selecting the padlock icon for a two-port RadioBlade (RBD2) transceiver locks the blade. With an MCRB, locking the top padlock as shown on the RadioBlade Control page will lock all carriers for that MCRB while selecting the padlock on the individual carrier will lock only that carrier.

MC-Series High-Power System 998--01 Rev X1 System Configuration Changes Appendix F. BER Test Procedure The Bit Error Rate (BER) Diagnostic Test is used to execute BER tests of the MC-Series system. The Diagnostic Test supports multi-channel RadioBlade (MCRB) transceivers in both the 900 MHz band and the 800 MHz bands and also two-port, 800-band RadioBlade (RBD2) transceivers. BER testing gives a pass/fail determination for each blade and should be performed on all blades in the RadioBlade shelf (RBS). The most common testing scenario involves acceptance-test plan (ATP) execution during incoming inspection and commissioning. The MC-Series system can be taken out of service for testing during a maintenance window. The RadioBlade transceivers can be locked as a group and then unlocked one-by-one for the BER tests. F.1 Prerequisites for Testing These procedures presume that the MC-Series system is in place at its site of service and operational. Therefore, the prerequisites for operation will already have been satisfied:

The T1 is live and has been tested. The datafill has been completed, including BR cabinet and position assignments, and conforms to the recommended datafill. All site cabling and installation work has been completed and all punchlist items corrected. The system is powered and operational. The software is at least Revision 14.x.xxx. In addition, the following conditions are required for BER testing:

The BER test requires that the RadioBlade Shelf be connected to an ISC. The RadioBlade transceiver under test must be in the active state and unlocked (UEA). F.2 Test Tool Signal generator (sig gen) A Motorola R2660 Communications Analyzer can be used as the source of the test signal for the MC-Series system during the BER test. F.3 Testing Strategy In the MC-Series system as in the Motorola Enhanced Base Transceiver Station (EBTS), BRs are identified by cabinet and position, with frequencies assigned in the datafill. BRs in the MC-Series are logical instances that map to physical RadioBlade transceivers. RBD2 and the MCRB transceivers can be mixed in a system (on a single RBS), and both the RBD2 and the MCRB can operate in a Quad BR configuration. Like the EBTS, the MC-Series system can be organized as a single sector (Omni), or as two or three sector site. The basic BER testing strategy is to record the Base Radio (BR) and corresponding RadioBlade configuration of the MC-Series system, and then test each blade across the power spectrum in its assigned range(s) of frequency. RadioFrame Networks, Inc. CONFIDENTIAL AND PROPRIETARY 119 System Configuration Changes MC-Series High-Power System 998--01 Rev X1 BER Test on an MCRB Because the MCRB supports up to six carriers, the BR to RadioBlade transceiver ratio can range from one-to-one up to six-to-one. BER testing confirms the functionality of the blade hardware itself at selected frequencies and sensitivity levels, allowing you to check functionality specifically in the assigned ranges. The MCRB can be viewed as a broadband RadioBlade transceiver in which up to six iDEN carriers are set up in a 1.25 MHz band centered at an optimal frequency. When testing an MCRB transceiver, the BER test start page allows an optional center carrier to be entered. By default, if only a carrier (no center carrier) is specified for the BER test, the test will be done at that specified carrier, with the band centered on the specified carrier. Entering both a carrier and a center carrier allows BER testing to be done at non-center carriers. The procedures in this guide cover BER testing of the full complement of RadioBlade transceivers. The BER testing methodology proceeds from sector to sector, testing each cabinet shelf and position in succession. Figure 80 summarizes the process. Figure 80 BER Test Flow F.4 Equipment Connection/Setup Set up the equipment to measure Rx BER as follows:

1 Connect a laptop to port 8 of the BIC CRIC using an Ethernet (CAT-5) cable. 2 Boot the laptop, start System Manager and log in. 3 Launch a browser session and then enter the MC-Series system IP address

MC-Series High-Power System 998--01 Rev X1 System Configuration Changes Motorola R2660 On the R2660, set the 10 MHz STD toggle switch to INT and power it up. Connect the TOR Rx port that is being tested (e.g., 900 Rx1 to test 900 MHz) to the RF IN/OUT or GEN OUT port on the R2660, depending on the desired test signal level. Note: Attenuate as required. F.5 BER Test Procedure Commonly, the BER test is performed during the process of commissioning an MC-Series system, and the system has not yet been brought online. If the test is to be performed on a production system, the system must be taken out of service during a maintenance window. For your notes during the BER tests, there is a test notes master form, Table 43, from which you can make copies. This form is useful both to organize your testing strategy and preserve the record of test results. RadioBlade Transceiver Pre-Test This section covers preparation for testing: determining the status of the RadioBlade transceivers in the system, taking the system out of service and preparing the blades and Sig Gen to run the tests. These steps presume that you are logged in to System Manager on the monitor laptop and that the Sig Gen is connected (Equipment Connection/Setup), F.4. 1 Display the RadioBlade Control page (Figure 81). (To navigate to this page from the System Manager home page, click the Performance Monitoring tab and then click the RadioBlade Control link at the top of the iDEN Performance Monitoring page.)

CONFIDENTIAL AND PROPRIETARY 121 System Configuration Changes MC-Series High-Power System 998--01 Rev X1 Figure 81 RadioBlade Control Page RadioBlade transceivers are listed on the RadioBlade Control page by slot number

(1 through 24). If a RadioBlade transceiver is administratively locked, the icon in the Locked/Unlocked column is closed. If the RadioBlade transceiver is unlocked, the lock is open. 2 For reference in restoring the original system configuration, record in your notes which RadioBlade transceivers are administratively locked. 3 Lock any unlocked RadioBlade transceivers so that none of them is transmitting. To lock a RadioBlade transceiver, select its open lock icon, and, when prompted, select Accept. Or you can use the lock all hot link to administratively lock all blades with one command. 122 CONFIDENTIAL AND PROPRIETARY TRADE SECRET INFORMATION RadioFrame Networks, Inc. MC-Series High-Power System 998--01 Rev X1 System Configuration Changes RadioBlade Transceiver BER Test This section covers the method to use to measure receiver BER and determine whether each RadioBlade transceiver passes. Testing is organized by sector to minimize the need to move the Sig Gen leads. Because you are testing an MC-Series system that is not in service, you can simply leave the leads connected to the sector Rx port at TOR for the duration of the tests on that sector. The testing method follows a nested loop

(summarized in F.3, Testing Strategy) until all blades either pass or fail. Once testing on a given RadioBlade transceiver has been completed (step 7), you repeat the test steps for the next transceiver. Once a given sector is completely tested, you move the leads to the next sector input port and repeat the test for each blade in the next sector. 1 Set the Motorola R2660 to generate an in-bound 1 x 6 test signal at the desired frequency and signal level into the Rx port that corresponds to the RadioBlade transceiver to be tested. 2 Determine the receive sensitivity threshold. Start at 120 dBm, and then increase in 2 dB increments until the BER drops below 2%. The receive sensitivity value should be less than 106 dBm at 2% BER. 3 Determine the max. level threshold. Start at 48 dBm and increase in 2 dB increments until the BER goes above 2%. The maximum input power should be greater than 40 dBm at 2% BER. 4 If either of the values called for in steps 2 and 3 is not attained, the RadioBlade transceiver has failed specifications and should be replaced. 5 Display the RadioBlade Control page (Figure 81), and make sure the RadioBlade transceiver that is to be tested is not locked. If it is locked, unlock it. If you are unlocking the blade, refresh the page every 30 seconds until the State of the RadioBlade transceiver has changed to UEA, approximately 3 minutes. 6 Select the Diagnostics tab (Figure 82), and then select Bit Error Rate Test.

If the warning Test Signal Timing Out of Lock appears, cycle power to the R2660 and set it up again to generate an in-bound 1x6 test signal at the desired frequency and signal level into the Rx port. It may take a few minutes for the R2660 test signal to stabilize. If the only BER measurements reported are 50%, NO DATA, or both, verify that all procedure steps have been completed. If no problems are found, cycle power to the R2660 and set it up again to generate an in-bound 1x6 test signal at the desired frequency and signal level into the Rx port. It may take a few minutes for the R2660 test signal to stabilize. If there's still no change after cycling power to the R2660, select the Stop Test button. Note:

11 When the BER test is complete, lock the RadioBlade transceiver that was under test. 12 Display the RadioBlade Control page, and lock the RadioBlade transceiver by selecting its lock icon so that it is closed (locked). Refresh the page every 30 seconds until the State of the RadioBlade transceiver has changed to 2. 13 Repeat Steps 1 through 11 for each RadioBlade transceiver to be tested on this Rx port. 14 Move the test leads to the next sector at TOR when all desired blades in the current sector have been tested and repeat the procedure.

Dangerous RF Emissions Precautions The MC-Series system has been approved for antennas up to +20 dBi. At energy levels within the approved range, operation may present hazards to life and health. Warning!

RF emission level is a function of the installation. Accordingly, it is the responsibility of the equipment owner, and not RadioFrame Networks, Inc., to apply signage to the site if it is required under 47 CFR 1.1310. Please carefully read and observe the following warnings!

This equipment is designed to generate and radiate radio frequency (RF) energy by means of an external antenna. When terminated into a non-radiating RF load, the base station equipment is certified to comply with Federal Communications Commission (FCC) regulations pertaining to human exposure to RF radiation in accordance with the FCC Rules Part 1 section 1.1310 as published in title 47 code of federal regulations and procedures established in TIA/EIA TSB92, Report on EME Evaluation for RF Cabinet Emissions Under FCC MPE Guidelines, Compliance to FCC regulations of the final installation should be assessed and take into account site specific characteristics such as type and location of antennas, as well as site accessibility of occupational personnel

(controlled environment) and the general public (uncontrolled environment). This equipment should only be installed and maintained by trained technicians. Licensees of the FCC using this equipment are responsible for insuring that its installation and operation comply with FCC regulations Part 1 section 1.1310 as published in title 47 code of federal regulations. Whether a given installation meets FCC limits for human exposure to radio frequency radiation may depend not only on this equipment but also on whether the environments being assessed are being affected by radio frequency fields from other equipment, the effects of which may add to the level of exposure. Accordingly, the overall exposure may be affected by radio frequency generating facilities that exist at the time the licensees equipment is being installed or even by equipment installed later. Therefore, the effects of any such facilities must be considered in site selection and in determining whether a particular installation meets the FCC requirements. FCC OET Bulletin 65 provides materials to assist in making determinations if a given facility is compliant with the human exposure to RF radiation limits. Determining the compliance of transmitter sites of various complexities may be accomplished by means of computational methods. For more complex sites direct measurement of power density may be more expedient. Persons responsible for installation of this equipment are urged to consult the listed reference material to assist in determining whether a given installation complies with the applicable limits. In general the following guidelines should be observed when working in or around radio transmitter sites:
