MM-018337-001 6 1 REGULATORY AND SAFETY INFORMATION 1.1 SAFETY SYMBOL CONVENTIONS The following conventions are used in this manual to alert the user to general safety precautions that must be observed during all phases of operation, service, and repair of this product. Failure to comply with these precautions or with specific warnings elsewhere violates safety standards of design, manufacture, and intended use of the product. Harris assumes no liability for the customer's failure to comply with these standards. The WARNING symbol calls attention to a procedure, practice, or the like, which, if not correctly performed or adhered to, could result in personal injury. Do not proceed beyond a WARNING symbol until the conditions identified are fully understood or met. CAUTION The CAUTION symbol calls attention to an operating procedure, practice, or the like, which, if not performed correctly or adhered to, could result in damage to the equipment or severely degrade equipment performance. The NOTE symbol calls attention to supplemental information, which may improve system performance or clarify a process or procedure. 1.2 RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION FOR FCC OCCUPATIONAL USE REQUIREMENTS Before using the mobile two-way radio, read this important RF energy awareness and control information to ensure compliance with RF exposure guidelines. This radio is intended for use in occupational/controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to remain below RF exposure limits. This radio is NOT authorized for general population, consumer, or any other use. CAUTION Changes or modifications not expressly approved by Harris could void the user's authority to operate the equipment. This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. It uses RF energy or radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high levels of x-rays, for example, can damage tissues and genetic material. Experts in science, engineering, medicine, health, and industry work with organizations to develop standards for exposure to RF energy. These standards provide recommended levels of RF exposure for both workers and the general public. These recommended RF exposure levels include substantial margins of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
MM-018337-001 7 ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of two-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Please refer to the following websites for more information on what RF energy exposure is and how to control exposure to assure compliance with established RF exposure limits: http://www.fcc.gov/oet/rfsafety/rf-faqs.html http://www.osha.gov./SLTC/radiofrequencyradiation/index.html 1.2.1 Federal Communications Commission Regulations Before it was marketed in the United States, the VRS7010 was tested to ensure compliance with FCC RF energy exposure limits for mobile two-way radios. When two-way radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a label directing users to specific user awareness information. The radio has an RF exposure product label. Also, this Installation and Product Safety Manual and the applicable Operator’s Manual include information and operating instructions required to control RF exposure and to satisfy compliance requirements. 1.3 COMPLIANCE WITH RF EXPOSURE STANDARDS The VRS7010 is designed and tested to comply with a number of national and international standards and guidelines regarding human exposure to RF electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment at duty-cycle times of up to 50% (50% transmit, 50% receive), and it is authorized by the FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure guidelines, the radio’s antenna radiates measurable RF energy only while it is transmitting (talking), not when it is receiving (listening), or in standby mode. The VRS7010 complies with the following RF energy exposure standards and guidelines:  United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR § 2 sub-part J.  American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE) C95.1-2005.  Institute of Electrical and Electronic Engineers (IEEE) C95.1-2005.  IC Standard RSS-102, Issue 2, 2005: Spectrum Management and Telecommunications Radio Standards Specification. Radiofrequency Exposure Compliance of Radiocommunication Apparatus (All Frequency Bands). CAUTION Table 1-1 and Table 1-2 list the recommended minimum safe lateral distances for a controlled environment and for unaware bystanders in an uncontrolled environment, from transmitting antennas (i.e., monopoles over a ground plane, or dipoles). This data is based upon the mobile radio installed in a motor vehicle with the radio transmitting at its rated RF power level. Transmit only when unaware bystanders are at least the uncontrolled recommended minimum safe lateral distance away from the mobile radio’s transmitting antenna.

Refer to Figure 7-1 on page 36 for applicable antenna part numbers. Installation guidelines presented in Section 7 are limited to metal-body motor vehicles or vehicles with appropriate ground planes. Use only the Harris-approved/supplied antenna(s) or an approved replacement antenna. Unauthorized antennas, modifications, or attachments can cause the FCC RF exposure limits to be exceeded. 1.3.2 Approved Accessories The radio has been tested and meets FCC RF guidelines when used with accessories supplied or designated for use with it. Use of other accessories may not ensure compliance with the FCC’s RF exposure guidelines, and may violate FCC regulations. For a list of approved accessories refer to Section 4 in this manual (begins on page 20) and/or the Products and Services Catalog. 1.3.3 Contact Information For additional information on RF exposure and other information, contact Harris using one of the contact links listed in Section 3.7 on page 19. 1.4 OCCUPATIONAL SAFETY GUIDELINES AND SAFETY TRAINING INFORMATION To ensure bodily exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use. Always adhere to the following basic guidelines:  The push-to-talk button should only be depressed when intending to send a voice message.  The radio should only be used for necessary work-related communications.  The radio should only be used by authorized and trained personnel. It should never be operated by children.
MM-018337-001 10  Do not attempt any unauthorized modification to the radio. Changes or modifications to the radio may cause harmful interference and/or cause it to exceed FCC RF exposure limits. Only qualified personnel should service the radio.  Always use only Harris-authorized accessories (antennas, control heads, speakers/mics, etc.). Use of unauthorized accessories can cause the FCC RF exposure compliance requirements to be exceeded. The information listed above provides the user with information needed to make him or her aware of a RF exposure, and what to do to assure that this radio operates within the FCC exposure limits of this radio. 1.5 COMMON HAZARDS The operator of any mobile radio should be aware of certain hazards common to the operation of vehicular radio transmissions. Possible hazards include but are not limited to:  Explosive Atmospheres — Just as it is dangerous to fuel a vehicle with its engine running, be sure to turn the radio OFF while fuelling the vehicle. If the radio is mounted in the trunk of the vehicle, DO NOT carry containers of fuel in the trunk. Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn the radio OFF when in any area with a potentially explosive atmosphere. It is rare, but not impossible that the radio or its accessories could generate sparks.  Interference To Vehicular Electronic Systems — Electronic fuel injection systems, electronic anti-skid braking systems, electronic cruise control systems, etc., are typical of the types of electronic devices that can malfunction due to the lack of protection from radio frequency (RF) energy present when transmitting. If the vehicle contains such equipment, consult the dealer for the make of vehicle and enlist his aid in determining if such electronic circuits perform normally when the radio is transmitting.  Electric Blasting Caps — To prevent accidental detonation of electric blasting caps, DO NOT use two-way radios within 1000 feet (305 meters) of blasting operations. Always obey the “Turn Off Two-Way Radios” (or equivalent) signs posted where electric blasting caps are being used. (OSHA Standard: 1926.900).  Radio Frequency Energy — To prevent burns or related physical injury from radio frequency energy, do not operate the transmitter when anyone outside of the vehicle is within the minimum safe distance from the antenna as specified in Table 1-1 and Table 1-2. Refer to Section 1.2 for additional information.  Vehicles Powered By Liquefied Petroleum (LP) Gas — Radio installation in vehicles powered by liquefied petroleum gas, where the LP gas container is located in the trunk or other sealed-off space within the interior of the vehicle, must conform to the National Fire Protection Association standard NFPA 58. This requires:  The space containing the radio equipment must be isolated and sealed from the space containing the LP gas container and its fittings.  Outside filling connections must be used for the LP gas container.  The LP gas container space shall be vented to the outside of the vehicle.  Vehicles Equipped with Airbags — For driver and passenger safety, avoid mounting the radio’s control head (or any other component) above or near airbag deployment areas. In addition to driver-side and passenger-side front-impact airbags, some vehicles may also be equipped with side-impact
MM-018337-001 11 airbags. For occupant safety, verify the location of all airbags within the vehicle before installing the radio equipment. 1.6 SAFE DRIVING RECOMMENDATIONS The American Automobile Association (AAA) advocates the following key safe driving recommenda-tions:  Read the literature on the safe operation of the radio.  Keep both hands on the steering wheel and the microphone in its hanger whenever the vehicle is in motion.  Place calls only when the vehicle is stopped.  When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep conversations brief.  If a conversation requires taking notes or complex thought, stop the vehicle in a safe place and continue the call.  Whenever using a mobile radio, exercise caution. 1.7 OPERATING RULES REGULATIONS Two-way radio systems must be operated in accordance with the rules and regulations of the local, regional, or national government. In the United States, the VRS7010 must be operated in accordance with the rules and regulations of the Federal Communications Commission (FCC). Operators of two-way radio equipment, must be thoroughly familiar with the rules that apply to the particular type of radio operation. Following these rules helps eliminate confusion, assures the most efficient use of the existing radio channels, and results in a smoothly functioning radio network. When using a two-way radio, remember these rules:  It is a violation of FCC rules to interrupt any distress or emergency message. The radio operates in much the same way as a telephone “party line.” Therefore, always listen to make sure the channel is clear before transmitting. Emergency calls have priority over all other messages. If someone is sending an emergency message – such as reporting a fire or asking for help in an accident, do not transmit unless assistance can be offered.  The use of profane or obscene language is prohibited by Federal law.  It is against the law to send false call letters or false distress or emergency messages. The FCC requires keeping conversations brief and confined to business. Use coded messages whenever possible to save on-the-air time.  Using the radio to send personal messages (except in an emergency) is a violation of FCC rules. Send only essential messages.  It is against Federal law to repeat or otherwise make known anything overheard on the radio. Conversations between others sharing the channel must be regarded as confidential.  The FCC requires self-identification at certain specific times by means of call letters. Refer to the rules that apply to the particular type of operation for the proper procedure.  No changes or adjustments shall be made to the equipment except by an authorized or certified electronics technician.
MM-018337-001 12 CAUTION Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of the United States may be punishable by a fine of up to $10,000, imprisonment for up to two (2) years, or both. 1.8 OPERATING TIPS The following conditions tend to reduce the effective range of two-way radios and should be avoided whenever possible:  Operating the radio in areas of low terrain, or while under power lines or bridges.  Obstructions such as mountains and buildings. In areas where transmission or reception is poor, communication improvement may sometimes be obtained by moving a few yards in another direction, or moving to a higher elevation.

MM-018337-001 15 3 INTRODUCTION This manual contains product safety and installation-related procedures for the VRS7010 vehicular repeater with mobile radio, together with the CH-721 control head. Installation procedures cover the mounting and cabling of the equipment, as well as the basic testing of the mobile radio and control head. An interconnection wiring diagram is included at the rear of this manual. Important product safety-related information is presented in Section 1. 3.1 GENERAL INFORMATION The VRS7010 is a combination Project 25 (P25) vehicular repeater for P25 trunked radio networks and a mobile radio for trunked and conventional radio networks. The VRS7010 consists of two (2) mobile systems. 3.1.1 Vehicular Repeater Base System (VRBS7010) The system that provides the RF link for nearby P25 radios when the VRS7010 is operating as a P25 vehicular repeater is called the Vehicular Repeater Base System (VRBS7010). As illustrated in Figure 5-2 on page 29, the VRBS7010 is formed by a Vehicular Repeater Base (VRB), a Traffic Controller module, and a 700 MHz duplexer module. The VRB is the transceiver for the RF link to nearby P25 radios. The Traffic Controller section interfaces the VRB to the VRM which transmits radio audio and control information to the site. The filter allows the VRB to operate with a single vehicle-mounted transmit-receive antenna. See Figure 3-1. 3.1.2 Vehicular Repeater Mobile System (VRMS7010) The system that provides network access is called the Vehicular Repeater Mobile System (VRMS7010). The VRMS7010 consists of an remote-mount M7300 mobile radio and an 800 MHz bandpass filter. The M7300 is the Vehicular Repeater Mobile (VRM) radio within the VRMS7010. The 800 MHz bandpass filter is in series with the M7300 radio’s antenna port and the vehicle-mounted antenna. This combination provides connectivity to an 800 MHz trunked or conventional radio network. The M7300 mobile radio is a dual-band 700 and 800 MHz mobile radio; however, in this application, only the 800 MHz RF band is supported. The VRMS7010 is shown in Figure 5-1 on page 28. Figure 3-1: Simplified Radio-to-Network Block Diagram with VRS7010
MM-018337-001 16 When operating as a P25 vehicular repeater, the VRS7010 provides an end-to-end P25 communication link between nearby P25 trunked radios and a P25 trunked radio network. The VRS7010’s network extension enables nearby P25 radios to maintain radio communications on a P25 radio network. In this mode, normal mobile radio communications cannot be accomplished from the radio’s control head. The radio’s microphone is disabled when it is operating in the P25 vehicular repeater mode. When it is operating as a mobile radio (i.e., P25 vehicular repeater mode disabled), the VRS7010 supports communications on P25 trunked and P25 conventional radio systems. As such, the VRS7010’s vehicular repeater functionality is not available. When the VRS7010 is operating as a mobile radio, the VRBS7010 is completely powered off and disabled and the VRMS7010 provides half-duplex voice and data communications. Voice communications are accomplished via the “push-to-talk” (PTT) type microphone and the speaker connected to the control head. A VRS7010 installation typically requires two (2) vehicle-mounted mobile antennas. One combination (“combo”) type mobile antenna is typically used for the VRMS7010 and its built-in GPS receiver, and another vehicle-mounted mobile antenna is required for the VRBS7010. If the VRMS7010 is not connected to a combo-type antenna (i.e., if the GPS receiver antenna is not integrated into the VRMS7010 transmit/receive antenna) and the VRMS7010 is equipped with a GPS receiver option, a third vehicle-mounted antenna is required for the GPS receiver within the VRMS7010. Antenna installation procedures are included in Section 7 of this manual. A wiring diagram is shown at the end of this manual. A VRS7010 installation also includes a CH-721 System model control head with a microphone and a speaker. This equipment provides the interface for the VRS7010’s operator/user. Mounting and installation accessories complete the mobile radio equipment package. Additional control head information is included in Section 3.3, and control head installation procedures are included in Section 10 of this manual. The VRS7010 and the CH-721 exceed many tough environmental specifications included within military standard MIL-STD-810F, automotive industry standard SAE-J1455, the radio industry standard TIA/EIA-603, and the radio standard established by the U.S. Forest Service. 3.2 OPERATING MODES The VRS7010 vehicular repeater with mobile radio has two (2) primary operating modes as described in the following subsections: 3.2.1 Standard Mobile Radio Mode When the VRS7010 is operating in the standard mobile radio mode, it functions like a normal mobile radio. The radio operator uses the interfaces of the connected CH-721 control head (i.e., display, control buttons/keys, mic and speaker) to control the radio and to communicate with other radio users and console dispatchers on a trunked or conventional radio network. Nearby P25 radios cannot be linked through the VRS7010 to the radio network when the VRS7010 is operating in this mode. The VRS7010’s vehicular repeater functionality is disabled when it is in this operating mode. The VRBS7010 is completely powered off and disabled. 3.2.2 Extended Coverage (XCOV) Vehicular Repeater Mode When the VRS7010 is operating in the extended coverage vehicular repeater mode, it provides the network extension interface that enables nearby P25 radios to access the P25 radio network through the VRS7010. This mode’s name is typically abbreviated “XCOV vehicular repeater mode,” “XCOV mode” or simply “VR mode.” Radio coverage for nearby P25 radios is extended because VRS7010’s high-performance mobile antenna system and higher transmitter output power used to access the P25 network. See Figure 3-1. When a nearby P25 radio is communicating through the VRS7010, it is considered
MM-018337-001 17 “connected” to and a “client” on the VRS7010. The VRS7010 cannot function as a standard mobile radio when it is operating in this mode. Typically, the VRS7010 operator places the radio into this mode via a menu selection or preset button press at the installation’s CH-721 control head. Likewise, the operator can disable this mode via a CH-721 control head menu selection or preset button press. Alternately, the radio installation may be wired so this mode can be enabled and disabled by an external switch. When the VRS7010 is operating in this mode, its VRBS7010 functions like a Voice and Data Over Control (VDOC) site for the nearby P25 radios. Essentially, the connected P25 radios and the VRBS7010 are linked together via P25 VDOC protocols on the VRBS7010 RF channel. When using the XCOV vehicular repeater mode, P25 radios operating through the VRS7010 maintain the following P25 functions across the two RF links:  P25 Group Call — Both digital clear voice and digital encrypted voice group calls are supported.  P25 Individual Call — Unit-to-unit calls both between two connected P25 radios and between a nearby P25 radio and a radio/console on the P25 radio network are supported.  P25 User ID — Caller identification information is sent between a connected P25 radio and the P25 radio network.  P25 Emergency — The link through the VRS7010 provides P25 emergency communications between the P25 radios connected to the VRS7010 and the P25 radio network.  P25 System All Call (from Network Only) — A system-wide all-call transmission from the P25 radio network is forwarded to P25 radios connected to the VRS7010.  Call Grant and Call Queued Tones — A P25 radio connected to the VRS7010 generates call grant and call queued tones in a similar manner as if was operating directly on the P25 radio network. A single VRS7010 allows attachment of up to sixty-four (64) nearby P25 radios. Each radio may communicate on the same talk group, or on multiple different talk groups (up to sixty-four maximum talk groups for one talk group per radio). Each connected P25 radio can communicate on the P25 network via the VRS7010. When operating in the XCOV vehicular repeater mode, calls transmitted from connected P25 radios are not routed to the VRS7010’s speaker. The VRS7010 supports end-to-end Advanced Encryption Standard (AES) encrypted calls. In other words, if a P25 radio connected to the VRS7010 is transmitting an encrypted call, the VRS7010 simply repeats the call to the network base station; it does not un-encrypt and then re-encrypt the call. 3.3 EQUIPMENT MOUNTING AND CONTROL HEAD The VRS7010 is designed for remote mounting in a motor vehicle’s trunk, or some other preferably unoccupied section in a vehicle, such as a fire truck’s equipment shelf. A 3-wire Controller Area Network (CAN) cable provides radio-to-control head(s) interconnection. One end of the CAN cable connects to a CAN port on the rear of the VRS7010’s VRMS7010 mobile radio and the other end connects to a CAN port on the rear of the CH-721 control head. Between the radio and the control head, the CAN link carries digitized microphone and speaker audio, and controlling data such as button presses and radio messages. For proper operation, the CAN link must be terminated appropriately on each end. The CH-721 System model control head provides the user/operator interface for the VRS7010. See Figure 10-2 on page 49. This control head has a large 3-line graphical vacuum-fluorescent display, front panel controls and buttons for user control of the mobile radio, an internal high-power audio amplifier to drive an externally-connected speaker, and a front panel microphone connector. It features a 12-key numeric
MM-018337-001 18 keypad that provides Dual-Tone Multi-Frequency (DTMF) keypad functionality and easier operator system/group selection, three (3) preset buttons, and an emergency/home button. As shown in Figure 10-2 on page 49, the CH-721 System model control head has several connectors located on its rear panel. These connectors include a DC power connector, two (2) CAN port connectors used for CAN link interconnections, an external speaker connector, a 9-pin serial port connector for connecting optional equipment such as a mobile data terminal, and a 25-pin multi-function connector. 3.4 OPERATING POWER The VRS7010 must be powered by an external +13.6-volt (nominal) DC power source. In mobile applications, the motor vehicle’s electrical system is utilized as the source of DC power. The VRS7010’s VRMS7010 and VRBS7010 are separately fused. For detailed specifications, see Section 2 of this manual which begins on page 13. The control head(s) connected to the radio is also powered by the same DC power source, but fused separately from the two (2) radios. When the control head is powered-up by the operator, it “wakes up” the VRM radio by transmitting data to the radio over the CAN link.

MM-018337-001 30 5.3 LOCATING COMPONENTS Plan the mounting locations of all components (VRS7010, CH-721, antennas, and cables) and determine the routes for all wiring and cables. Particularly consider the connection of the control head for planning purposes.  Determine the customer’s preferences, if any, for location of components. Comply with these preferences as long as they are consistent with safety recommendations and guidelines presented in this manual, and other generally accepted professional radio installation practices.  Nominal dimensions for the VRS7010 and the CH-721 are listed in Section 2.1 of this manual (page 13). These dimensions do not include any clearance space required for cabling, air circulation, access to mounting hardware, etc. Always plan for and include adequate clearance around the radios.  The VRMS7010 and the VRBS7010 must be located and mounted within approximately twelve (12) inches of each other.  Verify sufficient clearance behind the radios is provided so cables will not be stressed, crushed, twisted, or bent at severe angles. Also, the front and sides must have clearance for air circulation, access to mounting hardware, etc.  Connections at the VRS7010 are made through both “pigtail” type cables exiting the rear of its two radios, and panel-mount type connectors. This design minimizes the stresses associated with mating connections and it allows for easy connector mating. However, stresses can still be induced if adequate service looping is not employed. Connections to the control head is made with connectors mounted on the rear panel of each head, instead of “pigtail” type cables.  The VRS7010’s two (2) transmit-receive antennas must be located at least three (3) feet (0.92 meters) apart. Refer to Section 7 (page 35) for additional information. CAUTION All cables should have a service loop near each connector end. Do not bend the cables at severe angles near the connector end. Above all, after all components are installed, verify no cable is under any tension. Failure to do so may lead to damaged cables, causing intermittent radio operation or complete radio failure.
MM-018337-001 31 6 MOUNTING THE VRS7010’S VRMS7010 AND VRBS7010 This section provides details on mounting the VRS7010. The preferred mounting is on top of a firm, flat surface. See Figure 5-1, Figure 5-2, and refer to the respective wiring diagram at the end of this manual as necessary. Control head installation procedures are included in Section 10 (page 48) of this manual. The VRS7010 is relatively heavy, at approximately thirty (30) pounds (13.6 kilograms). Consider this weight when selecting a mounting surface. Refer to the specifications listed in Section 2.1 (page 13) of this manual for radio and control head weight specifications. Installation Kit MAMW-NZN8X (contents listed in Table 4-2 on page 21) contains the most complete set of materials for installing the radio. Therefore, the following instructions make repeated reference to this kit. Item numbers given in parenthesis refer to items in the kit. Prior to beginning the installation, verify the VRS7010 has the proper version of software installed and it has been configured for customer usage. CAUTION Though generally mounted in a trunk or remote location, the VRS7010 must be kept away from heat sources. Mounting it in a location which is out of direct sunlight is recommended but not required. Adequate ventilation space must be provided to the rear and side fins. The radio reduces its RF output power when its ambient temperature exceeds approximately +140o Fahrenheit (+60o Celsius). At a minimum, the mounting surface should be 16-gauge (approximately 1/16-inch thick) steel sheet metal. Mounting to plastic or other material with low tensile and shear strength could lead to an unsafe and/or failed mounting condition, turning the VRS7010 and its base bracket into a projectile during a high-shock incident such as a motor vehicle accident. If the selected mounting surface does not meet the minimum 16-gauge steel sheet metal requirement, the surface should be reinforced with a metal backing plate (not supplied) or it should be reinforced using some other approved mounting method. CAUTION Before drilling holes and/or installing mounting screws, verify these operations will not damage or interfere with any existing vehicle component (fuel tank, fuel line, transmission housing, existing vehicle wiring, etc.). Always check to see how far the mounting screws will extend below the mounting surface prior to installation. Always deburr drilled holes before installing screws. 6.1 INSTALL THE MOUNTING BRACKETS Two (2) identical Base Brackets (Item 1 in Table 4-2) are included with the installation kit. One bracket is used to mount the VRMS7010, and the other bracket is used to mount the VRBS7010. Two (2) Extension Brackets are also required to mount the VRM radio above its filter. The Extension Brackets basically extended the height of a Base Bracket to provide a mounting space above the 800 MHz bandpass filter for the VRM (M7300) mobile radio.
MM-018337-001 32 Typically, both Base Brackets are mounted in the vehicle’s trunk, on the top surface of a trunk tray or the trunk floor. However, both can be suspended from the trunk’s rear deck if the surface is completely flat, does not require any shimming and the gauge of deck’s sheet metal is high (16-guage minimum). The section of the cable which interconnects the DB-44 connector on the rear of the VRMS7010 to the DB-25 connector on the rear of the VRBS7010 is approximately eighteen (18) inches long. After the radios are secured within mounted brackets, they must be located so the respective connectors of the cable can mate to the connectors on the rear of the radios. Typically, both brackets must be mounted within approximately twelve (12) inches of each. The brackets/radios may be oriented parallel or perpendicular to each other.

MM-018337-001 33 When installed in a bracket, each radio protrudes several inches from the bracket’s front and back edges. Therefore, when selecting an exact mounting location, verify sufficient distance at the front and back for this and additional clearance. A minimum distance of three (3) inches is required from the rear edge of the bracket; however four (4) inches or more is recommended to improve radio installation and removal ease. A minimum distance of two (2) inches is recommended from the front edge of each bracket. The bracket is front/back symmetrical, and left/right symmetrical. As all installations differ, bracket-to-vehicle mounting screws are not included. The use of #10 stainless-steel machine screws, stainless-steel flatwashers and stainless-steel self-locking nuts is recommended. Alternately, #10 stainless-steel self-drilling screws and stainless-steel flatwashers may be used to speed installation time and/or if the underside of the mounting surface is not easily accessible. Self-drilling screws such as “TEK” screws do not require drilling of a pilot hole prior to installation. Do not use common self-threading sheet metal screws because they will loosen over time with vehicle vibrations. 1. Select a location for each Base Bracket—one location for the VRMS7010’s Base Bracket and one location for the VRBS7010’s Base Bracket. As previously stated, both brackets must be mounted within approximately twelve (12) inches of each other so the section of the cable which interconnects the two radios will have sufficient length. 2. Using each Base Bracket (Item 1 in Table 4-2) as a template and/or the dimensional information shown in Figure 6-1, mark and drill mounting holes into the mounting surface for each bracket. At least six (6) screws per bracket are recommended for proper installation: Four (4) in the screw holes of a bracket’s side tabs and two (2) in its center-most screw holes. If the installation prevents the installation of six screws, a minimum of four screws installed in the side tabs’ holes is required, per bracket. 3. Deburr all newly drilled mounting holes. 4. Set each bracket in place, and install and tighten the mounting screws. 5. Verify both brackets are firmly secured to the mounting surface. A secure mount prevents unreasonable vibration, which could damage the radio and/or cause its cable connections to loosen. 6. Attach an Extension Bracket to each side of the VRMS7010’s Base Bracket. Use two #8-32 pan-head screws per Extension Bracket. These screws are included in the installation kit (Item 3 in Table 4-2). When tightening the screws, push each Extension Bracket firmly down into the Base Bracket so each is firm and flush to the other when the screws are tight. 6.2 MOUNT THE RADIOS AND FILTER INTO THE BRACKETS The radios and the 800 MHz bandpass filter must now be mounted into the brackets as follows: 1. Slide the 800 MHz bandpass filter into the Base Bracket that has the two (2) attached Extension Brackets. The two (2) RF connectors must face towards the cabling area of the radio installation. 2. Secure the filter to the Base Bracket using three #8-32 pan-head screws (Item 3 in Table 4-2) per side. Tighten all six (6) screws with a screwdriver until the lock washers on the screws are fully compressed and the filter is firm and flush between the sides of the bracket. 3. Slide the M7300 mobile radio between the Extension Brackets, just above the 800 MHz bandpass filter. The rear of the radio must face towards the cabling area of the radio installation. 4. Secure the M7300 mobile radio to each Extension Bracket using six M5 Philips-head screws (Item 4 in Table 4-2), three (3) screws per radio side. These screws have a captive-type (SEMS) lockwasher. Tighten all six (6) screws with a screwdriver until the lock washer on each screw is fully compressed, and the filter is firm and flush between the brackets.
MM-018337-001 34 5. Slide the VRBS7010 into the other Base Bracket. The rear of the radio must face towards the cabling area of the radio installation. 6. Secure the VRBS7010 to this bracket using three #8-32 pan-head screws (Item 3 in Table 4-2) per side. Tighten all six (6) screws with a screwdriver until the lock washers on the screws are fully compressed and the radio is firm and flush between the sides of the brackets. 7. Check the mounting area for proper clearance for cable service looping and for air circulation, plus an area to secure and stow the excess cable lengths. Proper mounting is one factor that ensures optimal radio performance. An improperly mounted radio may experience degradation in the quality of voice and data communications.
MM-018337-001 35 7 ANTENNA INSTALLATION 7.1 ANTENNA MOUNTING LOCATIONS The VRS7010’s two (2) transmit-receive antennas must be located at least three (3) feet (0.92 meters) apart. For a standard motor vehicle, the VRMS7010 antenna must be installed at or near the center of the vehicle’s rooftop, and the VRBS7010 antenna must be installed in the center of the vehicle’s trunk lid. At this time, review all information presented in the REGULATORY AND SAFETY INFORMATION section of this manual (begins on page 6). Both transmit-receive antennas must be installed in accordance with the guidelines presented in the REGULATORY AND SAFETY INFORMATION section. Use Table 1-1 and Table 1-2 on page 9 and Figure 7-1 below as a guide for determining the best possible mounting configuration/location in order to reduce human exposure to radio frequency (RF) electromagnetic energy during transmit mode. Antennas must be mounted in locations on the vehicle as illustrated in Figure 7-1 and/or as described in the following subsections. Also, see Table 4-3 for additional information. Always follow manufacturer’s instructions when mounting an antenna. 7.1.1 Direct Center or Center-Rear of Rooftop for VRMS7010 Antenna The center of the vehicle’s roof is the best location for the VRMS7010 antenna (location  in Figure 7-1). For optimal performance, the mounting area under the antenna must be flat with a minimum radius of six (6) inches of metal ground plane. Locating the antenna directly in the center of the roof will minimize human exposure to RF electromagnetic energy. If obstructions such as a light bar or another antenna prevent the VRMS7010 antenna from being mounted in the direct center of the roof, the antenna should be mounted a minimum of one foot away from and behind the obstruction but in the middle of the roof with respect to the left and right sides of the vehicle (location  in Figure 7-1). The VRS7010’s two (2) transmit-receive antennas must be located at least three (3) feet (0.92 meters) apart. See Figure 7-1. The radio-end of each antenna cable must be labeled so each cable is connected to the correct radio. 7.1.2 Center of Trunk Lid for VRBS7010 Antenna For a standard motor vehicle, the VRBS7010 antenna should be located in the center of the vehicle’s trunk lid (location  in Figure 7-1). Locating the antenna directly in the center of the lid will provide the best P25 vehicular repeater mode improve coverage, and minimize human exposure to RF electromagnetic energy. The antenna cable of Harris-approved antennas should never be cut to a shorter length. Instead, excess cable must be tied and stowed. This not only prevents the antenna from radiating above its intended or configured power, but it also allows for future installation considerations such as a relocation of the mobile radio within the vehicle. Installations requiring longer cables are to be treated as custom and separately specified.

MM-018337-001 37 7.1.3 Rear Deck Lid for GPS Stand-Alone GPS Receive Antenna If the VRMS7010 does not use a GPS combination-type antenna and it is equipped with a GPS receiver, a stand-alone GPS receive antenna must be separately located and mounted. The vehicle’s rear deck lid (location  in Figure 7-1) is the recommended mounting location for this case. This locates the GPS antenna inside the vehicle. 7.2 ANTENNA INSTALLATION PROCEDURE Antennas must be installed before completing the radio installation. 7.2.1 Install and Connect Mobile Antennas Table 4-3 (page 23) and Figure 7-1 (page 36) list several types of mobile radio antennas available for use with the radio. As presented in the previous section, various mounting locations exist. 1. After selecting antenna mounting locations, refer to the antenna manufacturer’s assembly, mounting and testing instructions included with the antenna kit for installation guidance. If necessary, contact the Technical Assistance Center (see page 19 for contact information). 2. Route each antenna cable from the antenna to the rear of the respective radio. Keep each cable out of casual contact areas from persons and objects within the vehicle. Tie and stow as necessary to protect the cables. 3. Label the radio-end of each antenna cable. The cable from the rooftop-mounted antenna (highest of the two) should be labeled “VRMS7010 Ant.” and the cable from the trunk-mounted antenna (lowest of the two) should be labeled “VRBS7010 Ant.” Use the full length of coaxial cable included with each antenna. Never cut the cable to a shorter length, but rather coil any excess. Reducing the length of cable increases the output power radiated by the antenna, thereby exceeding the Maximum Permissible Exposure (MPE) allowance regulated by the FCC. CAUTION The VRS7010 installation’s VRMS7010 and VRBS7010 antennas are not interchangeable. Therefore, label the radio-end of each cable for future reference, as described in step 3. 4. Using an appropriate crimp tool, crimp the supplied TNC RF connector to the end of each antenna cable. See Figure 7-2 for crimping instructions. 5. Connect each antenna cable’s TNC plug-type (male) connector to the respective radio’s TNC receptacle-type (female) RF connector at the rear of the radio. The VRMS7010 antenna cable (labeled “VRMS7010 Ant.”) must be connected to the “ANTENNA” connector on the rear of the 800 MHz bandpass filter. The VRMS7010 antenna cable (labeled “VRBS7010 Ant.”) must be connected to the “pigtail” type antenna cable of the VRBS7010. Mate the connectors and turn the plug clockwise until finger-tight. This will be a temporary connection until the radios and antennas can be tested after the installation is complete (in accordance with test procedures presented in Section 16). The antennas should be connected now in case of accidental transmission.
MM-018337-001 38 (VS-AN-025167-010 Rev. A) Figure 7-2: Crimping Instructions for TNC RF Connector (Actual Size; Dimensions in Inches) 7.2.2 Connect RF Cable Between VRM Radio and 800 MHz Bandpass Filter A RF cable must be connected between the antenna connector of the M7300 and the 800 MHz bandpass filter as follows: 1. Obtain RF Cable CA-018378 from the installation kit (item 8 in Table 4-2). 2. Mate the cable’s male TNC connector the radio’s female TNC connector. Do not fully tighten at this time. 3. Mate the cable’s female TNC connector to the 800 MHz bandpass filter’s male TNC connector. 4. Using a pair of soft-jaw pliers, firmly tighten both of the cable’s TNC connectors. Do not overtighten. 7.2.3 Install and Connect GPS Antenna (If Required) The VRMS7010’s M7300 mobile radio may be equipped with an internal GPS receiver. If so, this receiver requires connection to an externally-mounted GPS antenna if the GPS functions will be utilized. Some installations may use a magnetic-mount stand-alone GPS antenna installed separately from the SMR mobile antenna. The following antenna installation procedure is recommended: 1. Once the mounting location is selected, refer to the antenna manufacturer’s mounting and testing instructions for installation guidance. If necessary, contact the Technical Assistance Center (see page 19 for contact information). 2. Route the cable from the GPS antenna to the rear of the radio. The cable should be kept out of casual contact from persons within the vehicle.
MM-018337-001 39 3. Connect the GPS antenna cable’s SMA plug-type (male) connector to the radio’s SMA receptacle-type (female) “pigtail” type RF connector at the rear of the radio. Mate the two connectors and turn the plug clockwise. Tighten using two 5/16-Inch combination or open-end wrenches. Do not over-tighten. Do not alter the length of cable from the GPS antenna. The SMA connector on the end of the antenna cable is not field-replaceable. Tie and stow excess cable as necessary. The GPS combo antenna kit includes a GPS antenna built into the base of the mobile antenna. No extra holes are required for the GPS cable when using this antenna. The antenna must be kept at least six (6) inches away from any other antenna mounted on the vehicle and have at least six inches of surface ground plane beneath it.
MM-018337-001 40 8 INTERFACE CABLE INSTALLATION 8.1 INTERFACE CABLE CA-012349-003 OVERVIEW Interface Cable CA-012349-003 interconnects the VRMS7010 to the VRBS7010. It also provides connections for various optional equipment, if necessary. The cable interconnects the 44-pin I/O connector on the rear of the VRMS7010 to the 25-pin connector at the rear of the VRBS7010. For connection of optional equipment, the cable breaks out into several smaller standardized connectors, allowing straightforward access to external I/O interfaces provided by the VRMS7010. The cable is shown in Figure 8-1 below. The cable’s installation procedure is included on page 42. MILLIMETERSMILLIMETERSMILLIMETERSMILLIMETERS (Made From PS-CA-012349 Rev.

Obtain Interface Cable CA-012349-003. It is included in the installation kit. 2. Mate the cable’s male 44-pin D-subminiature (DB-44) connector to the female 44-pin D-subminiature connector on the rear of the VRMS7010. Using a screwdriver, tighten the two jackscrews securely.
MM-018337-001 43 3. Mate the cable’s male D-subminiature 25-pin (DB-25) connector (labeled VRB) to the VRBS7010’s female 25-pin D-subminiature connector. Using a screwdriver, tighten the two jackscrews securely. 4. Tie and stow the cable.
MM-018337-001 44 9 DC POWER INSTALLATION Refer to the wiring diagram at the end of this manual as necessary when performing wiring procedures presented in this section. 9.1 OVERVIEW OF ON/OFF POWER WIRING CONFIGURATIONS Radio on/off power control is accomplished by the control head. When the control head is turned on, it “wakes-up” the VRMS7010 via data activity on the CAN link. The VRMS7010 automatically powers-up the VRBS7010 when the P25 vehicular repeater mode is enabled. The following power wiring configurations are supported:  Radio turns on and off automatically with vehicle’s ignition switch/key — This configuration allows the on/off state of the vehicle’s ignition switch/key to control the on/off power state of the radio. The white wire of the control head’s DC Power Cable is connected to a fused switched power source, typically identified as vehicle “Accessory” power. This source must switch on (up to positive (+) battery voltage potential) when the vehicle’s ignition switch/key turns on, and it must switch off (to near zero volts) when the ignition switch/key turns off. The required fuse rating is 3 amperes. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly.  Radio turns on and off with a manual switch — This configuration is used when, for example, the radio must remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is acceptable. The white wire of the control head’s DC Power Cable is connected to one side of a manually-controlled switch, and the other side of this switch is connected to unswitched and fused vehicle power. The required fuse rating is 3 amperes. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly.  Radio turns on with control head’s on/off/volume control (“hot wired”) — This configuration allows radio on/off power control only via the control head’s on/off/volume control. It may be desired if, for example, the radio must remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is not desired and/or not acceptable. The white wire of the control head’s DC Power Cable must be connected to unswitched and fused vehicle power. The required fuse rating is 3 amperes. The VRMS7010, the VRBS7010, and the control head require separately-fused main DC power. This is the red wire of each DC power cable. The switch power source to the control head is also separately fused. This is the white wire of the control head’s DC power cable. In-line type fuses and fuse holders are utilized. CAUTION Any DC input power provided to the radio shall be no higher or lower than 13.6 volts DC 10%. The DC input power should be free and clear of any AC noise or DC spikes above 18 volts. If the vehicle cannot meet these requirements, then DC conditioning will be required before any DC power is connected to the radio. This includes conditioning for both the radio’s main DC power input lead and for its switched ignition sense power input. DC conditioning can be accomplished by a noise filter or DC isolation equipment such as Harris part number FL-018314-001 or FL-018314-002, or similar units with equal specifications. The fuse must be placed in-line before any noise filter. Contact TAC for additional information.
MM-018337-001 45 9.2 POWER INSTALLATION PROCEDURE 9.2.1 Radio DC Power Cables and Main Fuse Holders Installation Each radio DC power cable has a 3-pin connector, a 20-foot red wire for the main power connection, a 20-foot white wire which is not used/not connected in this application, and a 4-foot black wire for the ground connection. Each cable is supplied with AGC-type waterproof fuse holders, AGC-type fuses, and non-insulated ring terminals. The following installation procedures are recommended: 9.2.1.1 Black Wire Connections (Ground Wires) 1. Obtain two (2) DC Power Cables, part number CA-012365-001. These cables are included in the installation kit. CAUTION Do not confuse the radios’ DC Power Cables which each has a 10-AWG red wire with the control head’s DC Power Cable which has a 12-AWG red wire. The radios require much more DC operating current than the control head. Therefore, each radio requires the larger size (10-AWG) wire. Control head DC Power Cable installation procedures are included in Section 10 of this manual. 2. Connect one DC Power Cable to the VRMS7010 by mating its 3-pin connector to the VRMS7010’s 3-pin DC power cable connector. Visually align the key and firmly push and turn the outer locking ring clockwise until it stops. A click will be sensed to confirm proper mating. 3. Connect the other DC Power Cable to the VRBS7010 using the same connection method. 4. Prepare to connect both cables’ black wires to vehicle ground by locating an area of vehicle metal within approximately three (3) feet of the two radios. This surface must have a solid and stable connection to vehicle ground (i.e., battery ground). CAUTION The radios must have a solid and stable ground connection to vehicle ground. If there is no well-grounded metal surface within approximately three (3) feet of the radios, a metal grounding strap or a heavy-gauge wire (with proper wire terminals) must be added between the metal surface and a solid and stable vehicle grounding point, preferably near the battery. Some vehicles are equipped with a high-current DC power access point (a vehicle option) that provides high-current power and ground studs, typically in the vehicle’s trunk area. In this case, the ground stud of the power access point can be considered a good vehicle ground, and used as such. Metal surfaces should be stripped of all paint and dirt to expose bare metal before attaching a grounding strap or wire terminal. To make all ground connections, the use of stainless-steel hardware with machine-screw threads, shelf-locking nuts and washers is recommended. 5. Strip the area of any paint or dirt to expose a bare metal surface, approximately ¾-inch square. 6. Drill a hole in the approximate center of the bare metal surface, and deburr it. A ⅜-inch non-insulated ring terminal is supplied with each cable to make the ground connection. Therefore, hole diameter should be appropriate for the utilized grounding screw/bolt size and type used to connect the ring terminals to the bare metal surface. This hardware is not supplied. 7. Cut the two (2) black wires to the required length plus some additional length for service loops in each wire, then strip insulation back approximately ¼-inch. 8. Crimp a ⅜-inch non-insulated ring terminal (supplied with the cable) to the end of each black wire.
MM-018337-001 46 9. Attach the two (2) ring terminals with black wires to the bare metal surface using stainless-steel self-locking hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware to ensure a reliable terminal-to-metal contact. Tighten securely. 10. Apply an approved paint or rust-inhibitor over the remaining exposed bare metal surface and around the ring terminal. Do not use an acid-based sealant. 9.2.1.2 Red Wires and Main Fuse Holder Connections (Radios’ Main Power Wires) 1. Continue installation of two (2) DC Power Cables by routing their 20-foot 10-AWG red wires to the location of the vehicle’s battery (or its main DC bus bar or stud). Route the wires through channels in the vehicle to the location of the battery. Remove interior panels, door kick panels, etc., as necessary. Protect the wires from possible chafing where necessary. Tie and stow it as necessary. The white wire of both radios’ DC Power Cables require no electrical connection. Rather than be cut from the two cables, it is recommended that these wires be routed up to the vehicle’s fuse box, coiled, labeled, and stowed for possible future use. The white wire of the control head’s DC Power Cable is the radio installation’s ignition sense input for on/off power control of both the control head and radio. Radio on/off power control is accomplished by the control head. The control head “wakes-up” the VRMS7010 via data activity on the CAN link. CAUTION Plan the routing of the two 10-AWG red wires carefully, using an existing access hole in the vehicle’s firewall if possible. Alternately, drill a new hole approximately 3/8-inch in diameter and install a small rubber grommet to protect the wires from chafing on the hole’s sharp metal edge. To prevent fumes from entering the passenger compartment, this hole/grommet/wire combination must also be sealed with a silicon-based sealer before completing the installation. CAUTION Do not install any wiring or fuse holder over or in the near vicinity of the vehicle’s engine. Excessive engine heat can cause permanent damage to these components and can lead to intermittent electrical connection to the battery. 2. Obtain two (2) waterproof inline fuse holders (HFB type) included with the DC Power Cables. 3. Observe and abide by the following WARNING! 4. Cut the red wires to the required lengths for connection to the battery’s positive (+) battery terminal (or the main DC bus bar or stud). 5. Prepare to splice the two (2) inline fuse holders into the red wires by cutting the red wires again, at approximately three (3) to six (6) inches from each end. 6. Strip all wire ends back approximately ⅜-inch each, place a fuse holder shell on each wire, and securely crimp a fuse holder terminal to each wire end. Before crimping, verify fuse holder shells are oriented in the correct directions (i.e., with each large end towards the wire end).
MM-018337-001 47 Before making connections to the battery’s positive post, carefully disconnect the battery’s negative (ground) cable(s). This will prevent tools or other metallic objects which come in contact with the battery’s positive terminal from shorting to vehicle ground, causing sparks or even a fire or an explosion! When disconnecting the negative cable(s), cover/insulate the positive post(s) if it is not already so a tool cannot short between the posts. Some vehicles, such as those with diesel engines have more than one battery; in this case, disconnect the negative cables at all batteries. Radio and control head fuses should not be installed until all wiring is complete. This will prevent the radio from powering up prematurely and/or causing an in-rush of current that could lead to shorting of the battery, sparks, or even fire. 7. Label each fuse holder and red wire appropriately (e.g., “VRS7010 VRMS7010: 15-AMP FUSE” and “VRS7010 VRBS7010: 15-AMP FUSE”). 8. Do NOT install fuses into the fuse holders at this time. 9. Crimp an appropriate electrical terminal to each short red wire. A ⅜-inch ring terminal is included with each cable for this purpose, but another terminal type (not supplied) may be used if required. 10. Connect both ring terminals directly to the battery’s positive post, or if present, to a stud on the battery’s main/non-switched power distribution terminal block.
MM-018337-001 48 10 CONTROL HEAD INSTALLATION 10.1 GENERAL INFORMATION Since the VRS7010 is a remote-mount mobile radio, it must be connected to a control head to provide the operator-to-radio interface. The CH-721 System model control head is used with the VRS7010. The front panel of the CH-721 System mode control head is shown in Figure 10-1. This control head has a large 3-line graphical vacuum-fluorescent display, front panel controls and buttons for user control of the mobile radio, an internal high-power audio amplifier to drive an externally-connected speaker, and a front panel microphone connector. It features a 12-key numeric keypad that provides Dual-Tone Multi-Frequency (DTMF) keypad functionality and easier operator system/group selection, three (3) preset buttons, and an emergency/home button. Other front panel components include a microphone connector and LED-type indicators. One LED indicator is the busy indicator that lights when the radio is receiving a call and one is the transmitter-enabled indicator that lights when the radio is transmitting. The front panel also has an ambient light sensor for automatic display dimming. Figure 10-1: CH-721 System Model Control Head Front Panel Figure 10-2 illustrates the control head’s rear panel. Connectors on the rear panel include two (2) CAN port connectors, a speaker audio (output) connector and a 25-pin D-subminiature (DB-25) accessory connector, and a 9-pin D-subminiature (DB-9) serial port connector. The DB-25 accessory connector is used for connection of optional equipment to the control head, such as a siren/light control system. The DB-9 serial port connector is typically only used during programming performed at the factory.

MM-018337-001 50 10.2 CONTROL HEAD MECHANICAL INSTALLATION 10.2.1 Selecting the Mounting Location When selecting a location for the CH-721 control head, first observe the safety and operator-convenience related information presented in Section 5.1 on page 27. Also always consider and include clearance for the microphone’s connector that must mate to the mic connector on the front panel of the head, and clearance for the connectors/cables that must mate to the connectors on the rear panel of the head. The CH-721 control head can be mounted under or on top of a mounting surface (typically the vehicle’s dash) as space permits using either the standard U-shaped mounting bracket or the optional mounting pedestal. Figure 10-3: Standard U-Shaped Control Head Mounting Bracket (Kit Part Number KT-008608) Figure 10-4: Optional Control Head Mounting Pedestal (Part Number MACDOS0012) Mounting Bracket (Shown positioned above control head) Control Head Mounting Pedestal MACDOS0012 (Pedestal can be attached to the bottom of the head, as shown, or it can be attached to the top of the head.)

MM-018337-001 51 10.2.2 Using the Standard U-Shaped Mounting Bracket If the standard U-shaped Mounting Bracket will be used to mount the control head, the following mounting procedure is recommended. This bracket is included with the Mounting Bracket Kit listed in Table 4-2 (on page 21). 1. Using the Mounting Bracket as a template, mark and drill mounting holes into the mounting surface as required. The round and elliptical holes in the bracket’s vehicle mounting surface are symmetrical so forward/backwards positioning is not important during this step. However, positioning is important in the next step. CAUTION When drilling holes, be careful to avoid damaging some vital part of the vehicle (fuel tank, transmission housing, etc.). Always check to see how far the mounting screws will extend below the mounting surface prior to installation. After drilling pilot holes, remove all metal shavings from them (i.e., deburr the holes) before placing the bracket and installing the mounting screws. 2. Postion the bracket at the mounting surface so the two round holes in its two side “ears” are nearest to the normal location of the operator (typically towards the rear of the vehicle) and the two slotted holes are farthest from the normal location of the operator (typically towards the front of the vehicle). 3. Install and tighten the mounting screws. Screws for mounting the bracket to the mounting vehicle’s surface are not included, as all installations differ. Self-tapping screws are recommended. Do not use common self-threading sheet metal screws because they will loosen over time with vehicle vibrations. 4. Verify the bracket is held firmly to the mounting surface. Firm mounting prevents unreasonable vibration, which could damage the control head and/or cause its cable connections to loosen. 5. Slide the control head into the bracket, placing the two pegs protruding from its left and right sides into the respective round holes in the bracket’s two side “ears.” 6. In each side “ear” of the mounting bracket, start a #8-32 socket-head cap (Allen) head screw with a lockwasher and a flat washer by inserting the screw through the slotted hole in the bracket and then into the threaded hole in the side of the control head. This hardware is included with Mounting Bracket Kit. The lockwasher should be adjacent to the screw head and the flat washer should be adjacent to the bracket. Turn each screw clockwise as observed from the head of the screw. 7. The control head can be positioned at various angles for best display viewing at the normal position of the operator. As necessary, turn it on the pegs to a good position and tighten both screws using an 1/8-inch hex key (Allen) wrench until the control head is held firmly in place. Do not over-tighten. 10.2.3 Using the Mounting Pedestal (Optional) An optional Mounting Pedestal, part number MACDOS0012, may be purchased separately to replace the standard U-shaped Mounting Bracket. This pedestal can be attached to the bottom of the control head as shown in Figure 10-4 and then mounted to a mounting surface below the two. It can also be attached to the top of the head and then mounted to a mounting surface above the two.
MM-018337-001 52 10.3 CAN CONNECTIONS 10.3.1 General Information The installation requires a CAN cable between every two “CAN devices” and CAN terminators on each end of the CAN link. The VRS7010’s VRMS7010 is considered a CAN device, and each CH-721 control head in the installation is also considered a CAN device. Figure 10-5 illustrates CAN cable and CAN terminator connections. Because CAN devices do not have internal terminators, the CAN link must be terminated at both ends via a CAN terminator. For Available CAN Cable Lengths and Respective Part Numbers, see Table 4-4 on page 25 Figure 10-5: CAN Cable and Terminator Connections Both the VRMS7010 and the control head have two CAN ports. Figure 5-1 on page 28 shows the radio’s two CAN port connectors, which are located on cable side of the I/O cable’s DB-44 connector. Figure 10-2 on page 49 shows the two ports on the control head’s rear panel. 10.3.2 Make CAN Link Terminations and Cable Connection Follow this procedure to complete CAN cable connections: 1. Connect the CAN Terminator (Item 11 listed in Table 4-2 on page 21) onto either one of the two smaller 3-pin connectors on the rear of the CH-721. This action makes the CAN termination at the control head end of the CAN link. When mating any CAN connection (terminators and cables), visually align the ¾-moon-shaped keys of the connectors, and then gently push and turn the outer locking ring of the plug (male) connector clockwise until it stops. A mild click will be sensed to confirm proper mating. Without visual alignment as a guide, it is possible with excessive force to mate the CAN connectors improperly. Damage to the connector(s) may result. Therefore, visual alignment is recommended when mating CAN connectors. 2. Route the CAN Cable (Item 9 listed in Table 4-2) through the vehicle’s interior wire/cable channeling to the VRMS7010. Remove interior panels, door kick panels, etc., as necessary. Protect the cable from possible chafing as necessary. 3. Attach the CAN Cable’s connector to one of the two CAN port connectors on the VRMS7010’s I/O cable.
MM-018337-001 53 4. Connect the other end of the CAN Cable to the open CAN port connector at the rear of the control head. 5. Connect the CAN Terminator (Item 11 in Table 4-2) onto either one of the two smaller 3-pin connectors on the VRMS7010’s I/O cable. This action makes the CAN termination at the radio end of the CAN link. 6. Loop, tie and stow the excess cable as necessary. 10.4 CONTROL HEAD POWER CABLE INSTALLATION Plan the route of the control head’s DC Power Cable carefully. Do not route the cable where it will be damaged by heat sources or by casual contact, and protect it from wire chafe per standard installation methods. The following procedures are recommended: 10.4.1 Install DC Power Cable and Make Power and Ground Connections 1. Connect the control head’s DC Power Cable (Item 6 listed in Table 4-2 on page 21) to the large 3-pin connector at the rear of the head. Visually align the key and gently push and turn the outer locking ring clockwise until it stops. A click will be sensed to confirm proper mating. 2. At the back of the control head, locate a nearby section of vehicle chassis ground and strip this area of any paint or dirt to expose a bare metal surface. 3. Cut the black wire of the control head’s DC Power Cable to the required length, plus a service loop of at least six (6) inches, then strip it and crimp a ⅜-inch ring terminal to it. Two (2) ring terminals of this type are included with the cable. 4. Drill a hole as necessary and attach this ring terminal to chassis ground. Use stainless-steel self-locking hardware (i.e., machine screws with washers and locking nuts) or other appropriate hardware to ensure a reliable terminal-to-metal contact. Tighten securely. CAUTION The control head must have a solid and stable ground connection to vehicle ground. If there is no well-grounded metal surface within approximately four (4) feet of the control head, the DC Power Cable’s black wire should be extended to a solid and stable vehicle grounding point, preferably near the battery. Some vehicles are equipped with a high-current DC power access point (option) that provides high-current power and ground studs, typically in the vehicle’s trunk area. In this case, the ground stud of the power access point can be considered a good vehicle ground, and used as such. Metal surfaces should be stripped of all paint and dirt to expose bare metal before attaching a ground wire. To make all ground connections, the use of stainless-steel hardware with machine-screw threads, shelf-locking nuts and washers is recommended. To extend the length of the ground wire, use at least 12-AWG wire and approved wire splicing techniques. 5. At the back of the control head, tie and stow the cable as necessary. 6. For the positive 12-volt DC main power source connection, route the cable’s red wire to the location of an unswitched 12-volt DC power source, typically near the vehicle’s battery. Remove interior panels, door kick panels, etc. Protect the wire from possible chafing as necessary. This is the control head’s main DC power source. 7. Obtain one of the waterproof inline fuse holders (HFB-type) included with the control head’s DC Power Cable.
MM-018337-001 54 8. Cut excess length from the red wire and splice the fuse holder into it, near the location of the unswitched 12-volt DC power source connection point. 9. Label this fuse holder and red wire appropriately (e.g., “CH-721 Main Power: 5-AMP FUSE”). 10. Using an appropriate electrical terminal, connect the red wire to the unswitched DC power source. A ⅜-inch ring terminal is included with the cable for this purpose, but another terminal type (not supplied) may be used if required. 11. Obtain the 5-amp AGC fuse included with the cable, and install it into the fuse holder. Do not share the control head’s fuse with any other device. Doing so can cause excess current to flow through the fuse, causing it to blow unnecessarily. CAUTION The fuse rating for the control head’s red wire is 5 amperes. The 3-amp fuse included with the cable must not be used for fusing the control head’s main DC power. It fuses the head’s white wire. 10.4.2 Connect DC Power Cable’s White Wire A review of the information presented in Section 9.1 (page 44) may be beneficial at this time. As required per the chosen power-up configuration, connect the white wire by following one of the three procedures presented in the respective sub-section that follows. Only the control head’s white wire must be connected to the ignition or switched power sense. When this vehicle line is asserted (i.e., power switched on), the control head automatically powers-up the VRMS7010 via the CAN connection. 10.4.2.1 Control Head and Radio Turn on with Vehicle’s Ignition Switch/Key With this wiring configuration, the control head and the VRMS7010 automatically turn on and off with the vehicle’s ignition switch/key. The white wire of the control head’s DC Power Cable is sometimes referred to as the “white ignition switch wire” or the “ignition sense input wire.” In this configuration, the white wire connects to a switched power source, typically identified as “Accessory” power, that switches on and off with the vehicle’s ignition switch/key. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly. The white ignition sense wire must be connected to a power source that switches from approximately zero volts to approximately +13.6 volts when the vehicle’s ignition switch/key is turned from the OFF position to the ACCESSORY and RUN positions. Use of a switched power source that is subject to voltage changes as a result of other actions, such as opening a vehicle door, may result in undesirable radio operation and/or a degradation of radio performance. 1. Locate the vehicle’s switched ignition or “Accessory” power connection point that will be used for the switched ignition 12-volt DC power source. This point is typically located at or near the vehicle’s fuse panel. It may be necessary to consult the vehicle manufacturer’s wiring diagram.
MM-018337-001 55 2. Route the white wire of the control head’s DC Power Cable from the back of the head to the area near this connection point. Protect the wire from possible chafing as necessary. 3. Obtain one of the waterproof inline fuse holders (HFB-type) included with the control head’s DC Power Cable or see the following NOTE. 4. Cut excess length from the white wire and splice the fuse holder into it, near the location of the connection point. 5. Using an appropriate electrical terminal, connect the white wire to the switched power connection point. An open-barrel spade terminal is included with the cable for this purpose, but another type of terminal (not supplied) may be used as required. 6. Obtain the 3-amp AGC fuse included with the cable, and install it into the fuse holder. 7. Tie and stow all wiring as necessary so it remains out of the way of casual contact and wire chafe is avoided. The waterproof inline fuse holder and AGC fuse included with the DC Power Cable must be used if the white wire connection point is located in a harsh environment such as in the vehicle’s engine compartment. However, if the connection point is not in a harsh environment, such as under the vehicle’s dash panel, Vehicle Fuse and T-Tap Kit FS24473 may be ordered and used to make the white wire connection. As shown in Figure 10-6, this kit includes an ATM fuse holder and fuse, T-tap crimp terminals for tapping into an existing vehicle switched power wire, and a quick-disconnect terminal. See Section 10.4.3 on page 56 for additional information. 10.4.2.2 Control Head and Radio Turn On with a Manual Switch With this wiring configuration, the control head and the VRMS7010 are manually turned on and off via an on/off switch mounted separately from the control head and VRMS7010, not through the vehicle’s ignition switch/key. This configuration is used when, for example, the radio must remain on even when the ignition key must be removed from the vehicle and a separate on/off switch is acceptable and/or required. In this configuration, the white wire connects to a fused switched power source such as that provided by a toggle switch mounted on the vehicle’s dash panel. When using this configuration, the CH-721 control head’s on/off/volume control must be left in the on position for automatic power-up/down to function properly. 1. Route the white wire of the control head’s DC Power Cable from the back of the head to an area near the location of the panel-mounted on/off switch. Protect the wire from possible chafing as necessary. 2. Cut a short section (6 to 8 inches) off the end of the white wire and strip the ends. 3. Obtain one of the waterproof inline fuse holders (HFB-type) included with the control head’s DC Power Cable, and crimp one half of it to one end of the short section of wire. 4. Using an appropriate electrical terminal, connect this short white wire to unswitched 12-volt DC power source at or near the vehicle’s fuse box. 5. Cut another section of white wire from the cable. This wire must be long enough to reach from this fuse holder to the location of the panel-mounted on/off switch. 6. Strip one end of this wire and crimp the other half of the fuse holder to this wire end. 7. Strip the other end of this wire and, using an appropriate electrical terminal, connect it to the common terminal of the switch. 8. Connect the white wire of the power cable to the load (switched) side of the switch.
MM-018337-001 56 9. If not already, mount the switch to the vehicle’s dash panel, or other customer-selected location. 10. Obtain the 3-amp AGC fuse included with the cable, and install it into the fuse holder. 11. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe is avoided. 12. Label this power switch accordingly. For example: “VRS7010 ON/OFF.” 10.4.2.3 Control Head and Radio Are “Hot Wired” In the “hot-wired” configuration, the control head and VRMS7010 are turned on and off only by the control head’s on/off/volume control located on the front panel of the control head. In this configuration, the control head’s white wire must be connected to unswitched and fused 12-volt vehicle power. Follow the procedure presented in Section 10.4.2.1, except connect the white wire to unswitched battery power instead of switched (“Accessory”) power. 10.4.3 Using Vehicle Fuse and T-Tap Kit (Optional) Instead of Waterproof Inline Fuse Holder (Standard) The waterproof inline fuse holder and AGC fuse included with the DC Power Cable must be used if the white wire connection point is located in a harsh environment such as in the vehicle’s engine compartment. In this case, disregard all information presented in this section, and follow one of the three procedures presented in Section 10.4.2 to connect the white wire. However, if the connection point is not in a harsh environment, such as under the vehicle’s dash panel, Vehicle Fuse and T-Tap Kit FS24473 may be ordered and used to make the white wire connection. As shown in Figure 10-6, this kit includes an ATM fuse holder and fuse, T-tap crimp terminals for tapping into an existing vehicle switched power wire, and a quick-disconnect terminal. The following installation procedure is recommended for this optional kit: 1. Locate the switched ignition or “Accessory” power wire (typically at or near the vehicle’s fuse block or in a vehicle wiring harness) that will be used for the switched ignition power source. It may be necessary to consult the vehicle manufacturer’s wiring diagram. 2. Route the white wire of the control head’s DC Power Cable from the back of the head to an area near the switched ignition power source. At the back of the head, be sure to maintain a cable service length of at least six (6) inches and do not loop the cable. 3. Cut a short section (6 to 8 inches) off the end of the white wire and strip each end of this short wire.

From the Vehicle Fuse and T-Tap Kit, locate the male-tab quick-disconnect terminal and crimp it to one end the short wire.
MM-018337-001 57 5. From the same kit, locate the ATM fuse holder and crimp it to the other end of the short wire. The holder has built-in crimpable joints. 6. Cut the excess length from the white wire of the control head’s power cable, strip it, and crimp it to the other side of the ATM fuse holder. 7. Pull enough of the switched ignition source wire out of the vehicle’s wiring harness so one of the T-tap terminals may be attached to it. 8. Two T-tap terminals are included in the kit. Based on the gauge of wire, select the proper terminal size: Red is for connecting to a 22 to 18-AWG wire, and blue is for connecting to an 18 to 14-AWG wire. 9. Attach the selected T-tap terminal by fitting the wire into its wire groove and snapping the two halves together with a pair of pliers as shown in Figure 10-7. 10. Push the male-tab quick-disconnect terminal into the T-tap terminal’s inlet until it is fully engaged. 11. Install the 2-amp ATM fuse into the fuse holder. It is recommended that a piece of electrical tape be wrapped around the fuse connection to keep the fuse from being jostled out of the holder. 12. Tie and stow these wires as necessary so they remain out of the way of casual contact and wire chafe is avoided. Diagram Courtesy of 3M Corp.

MM-018337-001 58 11 SPEAKER INSTALLATION Select a location for the speaker that will allow for proper listening range with a moderate volume setting. Total speaker cable length (of both cables) is approximately five (5) feet. Therefore, to include service loops in the cables, the speaker must be mounted within approximately 4.5 feet of the control head. 1. Install the speaker (Item 12 in Table 4-2) using the hardware and mounting bracket supplied with it. Also refer to the instructions included in the speaker for additional mechanical installation information. 2. Route the speaker’s cable to the rear of the control head. 3. Mate the Speaker Cable (Item 13 in Table 4-2) to the 2-pin connector at the rear of the control head by visually aligning the ¾-moon-shaped keys of the connectors, and then pushing and turning the outer locking ring of the cable connector clockwise until it stops. A mild click will be sensed to confirm proper mating. 4. Connect the speaker’s 2-pin plastic connector to the respective mating connector on the Speaker Cable. 5. Route the cables out of the way of casual contact, and tie and stow as necessary.
MM-018337-001 59 12 MICROPHONE ATTACHMENT There are several versions of microphones available for use with the CH-721 control head. Each has a 17-pin flush-mount type connector that mates with the microphone (“mic”) connector on the front panel of the control head. The mic’s connector includes a captive thumbscrew that secures it to the mic connector on the front panel of the control head. A microphone clip is included with each microphone. The radio can be configured to provide a monitor function when the microphone is cradled in the clip. Connect the mic to the control head and install the clip as follows: 1. As illustrated in Figure 12-1, grasp the mic’s connector with a thumb and index finger on the sides of the connector just adjacent to the thumbscrew. 2. Position connector just in front of the control head’s mic connector so its male pins can engage straight into the female (socket) pins of the control head’s mic connector. The thumbscrew must be oriented directly above the hanging mic cable. 3. Mate the two connectors by pressing them fully together. Do not apply any force to the thumbscrew when mating the connectors. 4. Tighten the thumbscrew finger-tight. Do not use a screwdriver to tighten it. 5. Using the microphone clip as a template, drill mounting holes in the surface of the selected location. 6. Attach the microphone clip to the mounting surface using self-threading screws. Select a location that has clearance for the mic when it is attached to the clip. 7. The microphone clip must be grounded to the vehicle’s chassis. If not mounted to a grounded metal surface, complete this requirement by adding a jumper wire attached from chassis ground to the clip. 8. Clip the microphone to the clip. Figure 12-1: Attaching the Microphone to the CH-721 Control Head As illustrated, do not apply any force to the thumbscrew whenmating the mic connectors.

Connect the DB-9 female connector labeled “GPS” of Interface Cable to the computer’s serial port DB-9 male connector—either directly or extended via a serial cable. Serial Programming Cable CA-013671-020 (20 feet) can be used to extend the length; see Section 13.1 for additional information. Tighten the screws firmly, and then route the cabling as required. If the computer is not equipped with a DB-9 serial port connector, the use of a suitable adapter is required, such as USB-to-RS-232 Adapter Cable CN24741-0001. 2. Follow the manufacturer’s instructions on processing the NMEA-formatted GPS data from the radio. Industry software to process GPS information through this interface is not supported by Harris.
MM-018337-001 64 15 INITIAL POWER-UP TEST 1. At the main inline fuse holders located near the vehicle battery (or DC power access point), insert a 15-amp AGC fuse into the fuse holder for VRMS7010 main power. The fuse was included with the respective DC Power Cable (installed per Section 9.2.1.2). 2. Insert another 15-amp AGC fuse into the fuse holder for VRBS7010 main power. The fuse was included with the respective DC Power Cable (installed per Section 9.2.1.2). 3. If not already, insert a 5-amp AGC fuse into the fuse holder for the CH-721 control head’s main power fuse. The fuse was included with the respective DC Power Cable. 4. If not already, near the vehicle’s fuse panel, install a 3-amp AGC fuse in the respective inline fuse holder. The fuse was included with the respective DC Power Cable. However, if Vehicle Fuse and T-Tap Kit FS24473 was used to make the control head’s ignition/switched power connection, install the 2-amp ATM fuse included with the T-tap kit. 5. Tie and stow all fuse holders and wiring to prevent excess vibration/movement. 6. Carefully reconnect the vehicle’s battery ground cable. 7. If not already, temporarily connect the two mobile antenna cables from the vehicle-mounted antennas to the female TNC RF connector at the rear of the two radios. These are temporary connections until test procedures in Section 16 are complete. 8. If the VRMS7010 is equipped with the GPS receiver option, permanently connect the antenna cable from the GPS antenna (or mobile/GPS combo antenna) to the female SMA connector on the rear panel of the radio. The male SMA connector on most GPS antenna cables has a 5/16-inch hex collar, so the use of a wrench of this same size is normally required for tightening. However, some may have collars with only knurled surfaces, so a standard wrench or torque wrench cannot be used. In either case, do not over tighten the connector and do not twist the cable when tightening. 9. If the installation is wired so the vehicle’s ignition key/switch turns the radio on and off, turn the switch to the Accessory or Run position. 10. If the control head is not already powered up, do so by rotating its on/off/volume control clockwise out of the detent position. 11. Verify the control head has powered-up by observing its display. If the display is not lit, refer to Section 9.1 as necessary. As long as the software configuration parameters have been loaded, successful installation is almost immediately realized:  After a short boot-up sequence, the control head displays login information and/or a talk group.  If no errors are displayed, the installation is most-likely properly wired.  If an error is displayed, recheck all cable connections, verify all fuses are properly installed, and verify battery power is getting to the radios’ main power fuses. If problems persist, contact the Technical Assistance Center (see page 19).  Consult the Operator’s Manual for operational information. Refer to Section 3.5 on page 19 as necessary. Refer to the following section for performance test information.
MM-018337-001 65 16 PERFORMANCE TESTS This section includes procedures to verify the performance of the installation’s antennas. Procedures include:  VRMS7010 and VRBS7010 Testing by Transmitting into a 50-Ohm RF Load/Terminator (“Dummy Load”)  VRMS7010 and VRBS7010 Testing by Transmitting into the Respective Radio Antennas CAUTION The accuracy of test results depends upon a DC power source in the range of 13.6 volts DC 10%, with a current capacity of greater than 15 amps. Make sure the vehicle’s battery is fully charged by running the engine for a few minutes before the test, and keep the engine running during the test procedures. Abide by the following WARNING! If the vehicle’s engine must remain running, the vehicle location should be well ventilated so exhaust fumes from the engine do not cause harm! CAUTION If a vehicle equipped with a VRS7010 requires jump-starting, the radio installation’s four (4) fuses should be removed from the fuse holders prior to jump-starting. Doing so will prevent damage to the VRS7010 and CH-721. Prior to installation, the VRS7010’s VRMS7010 and VRBS7010 transmit RF output power levels should be configured appropriately. The wide range of power levels indicated in the following procedures take into account such things as: customer’s requirements; measurement errors, especially to include uncalibrated equipment; cabling losses; and temperature variations. By no means should the result from Performance Testing in this section be construed as the exact value of power level outputs from the VRS7010, as values are set and more accurately measured in the factory. The values obtained in these test procedures determine a successful installation only.

At the rear of the VRMS7010, disconnect the antenna cable from the 800 MHz bandpass filter’s antenna connector (TNC connector labeled “OUTPUT”). If it is not already, label this cable as the “VRMS7010 Antenna” cable. This should be the cable from the highest (vehicle rooftop-mounted) antenna. 2. Using the Type N male to TNC male coaxial jumper cable, connect the antenna connector on the rear of the 800 MHz bandpass filter (connector labeled “ANTENNA”) to the wattmeter’s input connector. Refer to Figure 16-1 as necessary. 3. Connect a 50-ohm RF load/terminator to the wattmeter’s output connector.
MM-018337-001 67 4. At the rear of the VRBS7010, disconnect the antenna cable from the VRBS7010. If it is not already, label this cable from the antenna as the “VRBS7010 Antenna” cable. This should be the cable from the lowest (vehicle trunk lid-mounted) antenna. 5. Connect the other 50-ohm RF load/terminator to the VRBS7010. Use the Type N female to TNC male RF adapter. Refer to Figure 16-1 as necessary. 6. If not already, turn on the VRS7010 via the CH-721’s on/off volume control (or externally-mounted switch).

Set the VRS7010 (and thus the VRMS7010) to an 800 MHz test conventional channel. 8. Insert the 100-watt slug into the wattmeter and position the slug to measure forward RF output power. Rotate it as necessary. The arrow on the face of the slug must point away from the VRMS7010 and towards the 50-ohm load/terminator for forward power measurements. It is recommended that a test conventional 800 MHz channel be allocated for this testing. This same channel should be used during the antenna test procedure presented in the next section. Figure 16-1: Wattmeter Connections for VRMS7010 Antenna Tests 9. Set the wattmeter to measure peak RF power. 10. Key the VRMS7010 transmitter via the microphone’s PTT button. 11. For an 800 MHz band transmission, compare the wattmeter’s reading with the target RF output power range of between 22.1 and 55.5 watts (35 watts ±2 dB). This transmit output power range assumes the VRMS7010 is currently configured for high-power transmit. As stated in the NOTE on page 65, this wide power level range takes into account errors caused by test cable loss, etc.
MM-018337-001 68 Transmit only for as long as needed to take the measurement, then immediately disable the transmission. 12. If the wattmeter reading is within the range, record the measured value in the appropriate space on the data collection form near the end of this manual (page 74). If the wattmeter reading is outside the range, verify the VRS7010 power supply voltage (i.e., battery voltage) is within the specified range, recheck all connections and measure the RF output power again. If this fails to produce a reading within the range, replace it and repeat this procedure. If problems persist, contact the Technical Assistance Center (see page 19). 13. Un-key the transmitter by releasing the microphone’s PTT button. 16.3 VRMS7010 TRANSMITTING INTO ITS ANTENNA 1. To verify transmit output power of the VRMS7010, perform the test procedure presented in the previous section (Section 16.2). 2. Disconnect the 50-ohm load/terminator from the wattmeter. 3. Connect the cable from the vehicle-mounted VRMS7010 antenna (cable labeled “VRMS7010 Antenna”) to the wattmeter’s output connector, as shown in Figure 16-1. 4. If not already, turn on the VRS7010 via the CH-721’s on/off volume control (or externally-mounted switch). The front panel of the CH-721 is shown in Figure 10-1 on page 48. The VRS7010 powers-up in the mobile-only mode (vehicular repeater disabled). 5. Set the VRS7010 (and thus the VRMS7010) to an 800 MHz test conventional channel. Use the same channel that was used when performing the previous procedure. It is recommended that a test conventional 800 MHz channel be allocated for this testing. Otherwise, interference with other radio users in the system may occur. Also, during transmissions, always observe the RF exposure-related safety information presented in Section 1.2 of this manual (begins on page 6). 6. Insert the 100-watt slug into the wattmeter and position the slug to measure forward RF output power. Rotate it as necessary. The arrow on the face of the slug must point away from the VRMS7010 and towards the antenna for forward power measurements. 7. Set the wattmeter to measure peak RF power. 8. Key the transmitter via the microphone’s PTT button. 9. For an 800 MHz band transmission, compare the wattmeter’s reading with the target RF output power range of between 22.1 and 55.5 watts (35 watts ±2 dB). This transmit output power range assumes the VRMS7010 is currently configured for high-power transmit. As stated in the last NOTE on page 65, this wide power level range takes into account errors caused by test cable loss, etc. Transmit only for as long as needed to take the measurement, then immediately disable the transmission.
MM-018337-001 69 10. If the wattmeter reading is within the range, record the value in the appropriate space on the data collection form near the end of this manual (page 74). If the wattmeter reading is outside the range, verify the VRMS7010 power supply voltage (i.e., battery voltage) is within the specified range, recheck all connections, and measure the forward power again. If this fails to produce a reading within the range, check all cabling and connections, and repeat the testing procedure to this point. In the event the wattmeter reading still falls outside the range, replace the antenna, make sure all connections are seated firmly, and repeat the testing procedure. If problems persist, contact the Technical Assistance Center (see page 19). 11. Position the wattmeter’s 100-watt slug to measure reverse (reflected) RF power from the antenna. The arrow on the face of the slug must point away from the antenna and towards the VRMS7010 to measure reverse power. 12. Key the transmitter via the microphone’s PTT button. 13. Compare the wattmeter reading with the RF power output range of 2 watts or less. Transmit only for as long as needed to take the measurement, then immediately disable the transmission. 14. If the wattmeter reading is within the range, record the value in the appropriate space on the data collection form near the end of this manual (page 74). If the wattmeter reading is outside the range, make sure the antenna is consistent with the specified frequency range of the VRMS7010. Recheck all antenna connections, and measure the reverse power again. If this fails to produce a reading within the range, replace the antenna and repeat the entire antenna test procedure. Any value exceeding the maximum allowable reflected power value will result in a diminished RF output signal. If problems persist, contact the Technical Assistance Center (see page 19). 15. Un-key the transmitter by releasing the microphone’s PTT button. 16. Disconnect the coaxial cable jumper and wattmeter. 17. Permanently connect the cable from the vehicle-mounted VRMS7010 antenna to the 800 MHz bandpass filter’s antenna connector (labeled “ANTENNA”) by mating the two TNC connectors together. Use a pair of soft-jaw pliers to gently tighten this connection. Do not over tighten and do not twist the antenna cable. 18. Make several test calls on the radio system to verify VRMS7010 operation. Before making the calls, select another conventional channel(s), as required to verify operation. To prevent RF leakage and ensure peak performance, make sure the RF connectors are tight, but do not over-tighten so connector damage will not occur. Improper installation of the RF cables may lead not only to poor radio performance but also to harmful exposure to RF electromagnetic energy.
MM-018337-001 70 16.4 VRBS7010 TRANSMITTING INTO A 50-OHM LOAD/TERMINATOR 1. If it is not already, disconnect the VRBS7010 antenna cable at the rear of the VRBS7010. Label this cable from the antenna as the “VRBS7010 Antenna” cable. This should be the cable from the lowest (vehicle trunk lid mounted) antenna. 2. Using the Type N male to TNC male coaxial jumper cable, connect the antenna connector at the rear of the VRBS7010 to the wattmeter’s input connector. See Figure 16-2. 3. Connect a 50-ohm RF load/terminator to the wattmeter’s output connector. 4. Insert a 5-watt slug into the wattmeter and position the slug to measure forward RF output power. Rotate it as necessary. The arrow on the face of the slug must point away from the VRBS7010 and towards the 50-ohm load/terminator for forward power measurements. 5. Set the wattmeter to measure peak RF power. 6. If not already, turn on the VRS7010 via the CH-721’s on/off volume control (or externally-mounted switch). The front panel of the CH-721 is shown in Figure 10-1 on page 48. The VRS7010 powers-up in the mobile-only mode (vehicular repeater disabled). Refer to the operator’s manual as necessary. 7. Switch the VRS7010 to a P25 trunked radio network (i.e., make a “system” change if necessary). 8. Enable/Activate the extended coverage (XCOV) vehicular repeater mode as follows: a. Press the control head’s MENU button. b. Use the control head’s / Ramp Control to scroll through the menu until “P25 Menu” appears in the middle line of the display. c. Press the MENU button again. After a short delay, “VR Standby” will appear in the display, indicating the VRS7010 is operating in XCOV vehicular repeater mode and waiting for (client) radios to connect to it. When one or more radios connect, the display changes to “VR Active.” Within twelve (12) seconds of enabling the XCOV vehicular repeater mode, the VRBS7010 should begin transmitting control channel information on a 700 MHz RF channel.
MM-018337-001 71 Figure 16-2: Wattmeter Connections for VRBS7010 Antenna Tests 9. For the 700 MHz band transmission, compare the wattmeter’s reading with the target RF output power range of between 2.4 and 3.8 watts (3 watts ±1 dB). This transmit output power range assumes the VRBS7010 is currently configured for high-power transmit. 10. If the wattmeter reading is within the range, record the measured value in the appropriate space on the data collection form near the end of this manual (page 74). If the wattmeter reading is outside the range, verify the VRS7010’s power supply voltage (i.e., battery voltage) is within the specified range, recheck all connections and measure the RF output power again. If this fails to produce a reading within the range, replace it and repeat this procedure. If problems persist, contact the Technical Assistance Center (see page 19). 11. At the control head, disable P25 vehicular repeater mode. The VRBS7010 should immediately stop transmitting, as indicated by the wattmeter. 16.5 VRBS7010 TRANSMITTING INTO ITS ANTENNA 1. To verify transmit output power of the VRBS7010, perform the test procedure presented in the previous section (Section 16.4). 2. Disconnect the 50-ohm load/terminator from the wattmeter. 3. Connect the cable from the vehicle-mounted VRBS7010 antenna (cable labeled “VRBS7010 Antenna”) to the wattmeter’s output connector. See Figure 16-2.
MM-018337-001 72 4. Insert a 5-watt slug into the wattmeter and position the slug to measure forward RF output power. Rotate it as necessary. The arrow on the face of the slug must point away from the VRBS7010 and towards the 50-ohm load/terminator for forward power measurements. 5. Set the wattmeter to measure peak RF power. 6. If not already, turn on the VRS7010 via the CH-721’s on/off volume control (or externally-mounted switch). The front panel of the CH-721 is shown in Figure 10-1 on page 48. The VRS7010 powers-up in the mobile-only mode (vehicular repeater disabled). 7. Enable the extended coverage (XCOV) P25 vehicular repeater mode. Refer to step 8 in the previous section (Section 16.4) as necessary. If no radios are connected to the VRS7010, “VR Standby” is indicated in the control head’s display. When one or more radios connect, the display changes to “VR Active.” Within twelve (12) seconds of enabling the XCOV vehicular repeater mode, the VRBS7010 should begin transmitting control channel information on a 700 MHz RF channel. Since the VRS7010’s VRBS7010 automatically begins transmitting soon after enabling the vehicular repeater mode, before enabling this mode, an antenna must be connected to the VRBS7010 and VRMS7010 antennas and personnel should be at least the minimum safe distance from these two (2) antennas. Minimum safe distances from the VRMS7010 antenna are listed in Table 1-1 (on page 8). Minimum safe distances from the VRBS7010 antenna are listed in Table 1-2 (on page 9). 8. For the 700 MHz band transmission, compare the wattmeter’s reading with the target RF output power range of between 2.4 and 3.8 watts (3 watts ±1 dB). This transmit output power range assumes the VRBS7010 is currently configured for high-power transmit. 9. If the wattmeter reading is within the range, record the value in the appropriate space on the data collection form near the end of this manual (page 74). If the wattmeter reading is outside the range, first verify the VRBS7010 antenna’s driven element is properly trimmed. Before making any antenna adjustments, be sure to disable P25 vehicular repeater mode so the VRBS7010 will stop transmitting. Next, verify VRBS7010 power supply voltage (i.e., battery voltage) is within the specified range, recheck all connections, and measure the forward power again. If this fails to produce a reading within the range, check all cabling and connections, and repeat the testing procedure to this point. In the event the wattmeter reading still falls outside the range, replace the antenna, make sure all connections are seated firmly, and repeat the testing procedure. If problems persist, contact the Technical Assistance Center (see page 19). 10. At the CH-721, disable the P25 vehicular repeater mode. The VRBS7010 should immediately stop transmitting, as indicated by the wattmeter. 11. Position the wattmeter’s 5-watt slug to measure reverse (reflected) RF power from the antenna. The arrow on the face of the slug must point away from the antenna and towards the VRBS7010 to measure reverse power. 12. At the CH-721, enable P25 vehicular repeater mode. Within twelve (12) seconds, the VRBS7010 should begin transmitting control channel information on a 700 MHz RF channel. 13. Compare the wattmeter reading with the RF power output range of less than ½ watt.

In the event the wattmeter reading still falls outside the range, replace the antenna, make sure all connections are seated firmly, and repeat the testing procedure. If problems persist, contact the Technical Assistance Center (see page 19). 15. At the CH-721, disable P25 vehicular repeater mode. The VRBS7010 should immediately stop transmitting, as indicated by the wattmeter. 16. Disconnect the coaxial cable jumper and wattmeter. 17. Permanently connect the cable from the vehicle-mounted VRBS7010 antenna to the VRBS7010 antenna connector at the rear of the VRBS7010. Mate the two TNC connectors together. Use two pairs of soft-jaw pliers to gently tighten this connection. Do not over tighten and do not twist the cable. 18. Re-enable extended coverage (XCOV) P25 vehicular repeater mode and make several test calls between P25 radios connected to the VRS7010. To prevent RF leakage and ensure peak performance, make sure the RF connectors are tight, but do not over-tighten so connector damage will not occur. Improper installation of the RF cables may lead not only to poor radio performance but also to harmful exposure to RF electromagnetic energy.
