Chapter 1 Introduction Chapter 1 Introduction This manual covers the installation procedures for VXD Series Mobile Radios and accessories re- quired to complete the radio system. The radio system consists of a control head, radio, antenna, mi- crophone, speaker, cabling, and accessories.
Chapter 1 Introduction 1.1.3 Connections on the Back of the Radio Figure 1-3 shows the connections that are found on the back of the radio. For complete pin configuration of the rear accessory connector, see Figure 4-2, on page 4-2. Figure 1-3 Back View of the Mobile Radio Page 8...
Chapter 1 Introduction 1.2 Standard Configurations Currently the mobile radio can only be dash-mounted. 1.2.1 Dash Mount Configuration In the dash mount configuration of the mobile radio, the control head is mounted on the front of the transceiver housing. Electrical connection between the two takes place within the radio via a flexible cable between the connectors on the front of the transceiver and at the back of the control head.
Chapter 1 Introduction 1.3 Base/Control Stations If the mobile radio equipment is installed at a fixed location and operated as a control station or as a fixed unit, the radio and antenna installation must comply with the following requirements in order to ensure optimal performance and compliance with the Product Safety and RF Energy Exposure chapter in the Operating Manual: For outdoor antenna installations, proper site grounding and lightning protection are vitally...
Chapter 2 Reducing Noise Interference Chapter 2 Reducing Noise Interference 2.1 Introduction Electrical noise generated by the electrical system of a vehicle, as well as local ambient noise, can interfere with normal operation of mobile radios. Satisfactory operation of a mobile radio may require slight or heavy noise reduction, depending upon the relative strength of the radio signal, and upon the ability of the radio to reject undesired noise.
Chapter 2 Reducing Noise Interference It is impractical to prevent all arcing in the standard vehicle electrical system. In an 8-cylinder engine running at 2,000 RPM, arcing occurs across the spark plugs at a rate of 8,000 sparks per minute or 133 sparks per second.
Chapter 2 Reducing Noise Interference 2.2 Operation of a Conventional Ignition System 2.2.1 Introduction To effectively reduce ignition interference in a vehicle, it is well to understand the operation of an auto- mobile ignition system. Ignition is necessary in a gasoline engine to ignite the gasoline vapor and the air mixture in its cyl- inders.
Chapter 2 Reducing Noise Interference When the breaker points open, primary current decreases and, by self-induction, an electromotive force is induced in the primary which is many times greater than the battery voltage. The high voltage inducted in the coil secondary causes a spark across the distributor rotor-to-spark plug wire gap and then across the spark plug gap for a short interval of time when the breaker points open.
Chapter 2 Reducing Noise Interference Radiated noise must be attacked after conducted and induced noise has been satisfactorily sup- pressed. The vehicle ignition system is usually the primary source of this interference. Antenna place- ment can be critical in some installations. Remember that static discharge generates static or radiated noise and will probably be generated only when the vehicle is in motion.

Mount Capacitor (0.1µF Coaxial Type) to vehicle chassis Battery Post using lockwasher and self-tapping screw.
Chapter 2 Reducing Noise Interference 2.4.3 Alternator/Generator Whine This type of interference is characterized by a high-pitched whine which varies with engine speed. A 0.5 μF coaxial capacitor can be used to bypass the whine. For generators, the capacitors is connected in the armature lead.

Chapter 3 Installation Details for Standard Configurations Chapter 3 Installation Details for Standard Configurations 3.1 Planning the Installation The mobile radio operates only in negative ground electrical systems. Before starting the radio installa- tion, make sure that the ground polarity of the vehicle is correct. Accidentally reversing the polarity will not damage the radio, but will cause the cable fuses to blow.
Chapter 3 Installation Details for Standard Configurations 3.1.3 Wiring Diagrams Figure 3-2 shows the wiring diagrams for some of the possible configurations. Identify the configura- tion that you are installing, and use the diagram when planning the installation. ANTENNA FUSE BATTERY RF ANTENNA RED LEAD...
Chapter 3 Installation Details for Standard Configurations 3.2 Radio Mounting DO NOT mount the radio on a plastic dashboard without first reinforcing the dashboard; the weight of the radio may crack or break the dashboard. DO NOT mount the radio on a flat or concave surface where the radio could be partially submersed in water.
Chapter 3 Installation Details for Standard Configurations 3.2.1 Dash Mount with Trunnion 1. Select the location to mount your radio on the transmission hump (see Figure 3-4) or under the dash (see Figure 3-5). When mounting the trunnion on the transmission hump take care the trans- mission housing is not affected.
Chapter 3 Installation Details for Standard Configurations 3.2.2 Locking Kit (Optional) 3.2.2.1 All Radios If an optional locking kit is used (shown in Figure 3-6), position the lock bottom housing on the trunnion before installing the radio mounting screws. Then slip the top lock housing on and remove the key. You can install the lock on either side of the radio.
Chapter 3 Installation Details for Standard Configurations 3.2.3.2 To Mount the radio in the frame 1. Provide the electrical connections for the radio (power, antenna, accessories). 2. Plug in all the connectors and push the radio firmly into the mounting frame until the two springs snap into place (shown in Figure 3-7).
Figure 3-8 Cabling Interconnect Diagram for Dash Mount 3.4 Ignition Sense Cable Vertex Standard supplies an ignition sense cable and recommends that it be used with every mobile installation. The ignition sense cable allows the radio to be turned on and off with the vehicle ignition switch, and allows the radio to “remember”...
NOTE: For mobile radios with rated power of 7 watts or less, the only installation restrictions are to use only Vertex Standard approved antennas and install the antenna externally on metal body ve- hicles. For mobile radios with rated power greater than 7 Watts, always adhere to all the guide- lines and restrictions in Section 3.5.1 below.
Chapter 3 Installation Details for Standard Configurations 3.5.2 Antenna Installation Procedure 1. Mount the antenna according to the instructions provided with the antenna kit. Run the coaxial ca- ble to the radio mounting location. If necessary, cut off the excess cable and install the cable con- nector.
NOTE: Applying excessive force with a tool can cause damage to the antenna or the connector (e.g., stripping threads, deforming the collar or connector, or causing the connector to twist in the housing opening and break). Vertex Standard recommends the following sequence to ensure proper attachment of the system (see Figure 3-10): Figure 3-10 Mini-UHF Connection 1.
Chapter 3 Installation Details for Standard Configurations 3.6 Microphone Hang-Up Clip 3.6.1 Standard Hang-Up Clip The hang-up clip must be within reach of the operator(s). Measure this distance before actually mount- ing the bracket. Since the bracket has a positive-detent action, the microphone can be mounted in any position.

The accessories must be installed through the rear accessory connector that is located on the rear of the radio, adjacent to the power connector. Most of the Vertex Standard-approved accessories are supplied with female terminals crimped to a 20-gauge wire specifically designed to fit the plug of the rear accessory connector.
