MM-018337-001 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.
MM-018337-001 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).
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.

MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 9. Attach the two (2) ring terminals with black wires to the bare metal surface using stainless-steel selflocking 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.
MM-018337-001 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.
MM-018337-001 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.

MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 12 MICROPHONE ATTACHMENT There are several versions of microphones available for use with the CH-721 control head.

MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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.
MM-018337-001 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).
MM-018337-001 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.
MM-018337-001 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, 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. Verify VRBS7010 power supply voltage (i.e.
