Information for Vehicles with Electronic Anti-Lock/Anti-Skid Brakes 8. Repeat Step 7, except do so while speaking into the microphone. 9. Release the brake pedal completely and accelerate the vehicle to a speed of 20 miles (30 kilometers) per hour. Ensure that a minimum of two vehicle lengths is maintained between the front of the vehicle and any object in the vehicle’s forward path.
vi Information for Vehicles with Electronic Anti-Lock/Anti-Skid
1 Chapter 1 Introduction 1.1 General Information There are two methods of installing your mobile radio: 1. The standard radio package contains a direct mounting trunnion and power cables. 2. CM200/CM300 mobile radios may be mounted in the dashboard of a car using the required DIN Mount Kit FTN6083. An accessory connector on the rear of the radio (see Figure 4-1) enables you to attach different accessories required for the installation.
2 Chapter 2 DC Power Cable Installation 2.1 ! Planning the Power Cable Installation CAUTION: This radio must be operated only in negative ground electrical systems. Operating the radio on a positive ground system will cause the cable fuse to short-circuit. Check the vehicle ground polarity before you begin the installation. The 10 foot (3 m) DC power cable shipped with the radio should be long enough to be installed in most vehicles.

Connect the black lead of the power cable to the nearest vehicle chassis ground point, which is usually the central ground point near the battery (using the provided ring lug if necessary). Shorten the black lead to remove any excess cable. (See Figure 2-2.) NOTE Locate a good vehicle ground point.

8 Chapter 4 Antenna Installation 4.1 Antenna Installation and Compliance with Radio Frequency (RF) Energy Safety Standards IMPORTANT NOTE To assure optimum performance and compliance with RF Energy Safety standards, this antenna installation guidelines and instructions are limited to metal-body vehicles with appropriate ground planes and take into account the potential exposure of backseat passengers and bystanders outside the vehicle.
Antenna Installation 4. 9 Mounting restrictions for certain radio models For 40 Watt UHF models, the 1/4 wave antenna should be mounted only in the center area of the roof, not on the trunk lid, to assure compliance with RF Energy Safety standards. 5. Ensure that the antenna cable can be easily routed to the radio. Route the antenna cable as far away as possible from any vehicle electronic control units and associated wiring. 6. Check the antenna location for any electrical interference. 7.
10 Chapter 5 Installation Options 5.1 Mobile Dashboard Mounting 5.1.1 Installing the Mounting Frame into the Dashboard 1. Open the radio cut-out in the dashboard to ISO 7736 specification (182mm x 53mm). 2. Insert the mounting frame into the dashboard cut-out and retain it by bending back the tabs (using all 6 where possible). Check that the orientation of the frame is correct by ensuring that the word "TOP" is facing upward. NOTE 1.
Installation Options 5.1.3 11 Removing the Radio from the Mounting Frame 1. Push the two demounting tools through the openings in the mounting frame until the two springs release the radio. 2. Slide out the radio. NOTE 1. The fixing tabs should be checked for tightness each time the radio is removed. The tabs are easily tightened by twisting a large flat-bladed screwdriver in the slot behind the tabs. 2. The mounting frame is not designed for regular mounting and demounting. 5.
12 5.3 Installation Options Visor Microphone Installation 1. Carefully select the installation location for the visor-mounted microphone. Achieve optimum performance of the microphone’s hands-free circuitry by mounting the microphone in one of two locations: • on the sun-visor directly above the driver, or • on the headliner just above the driver. The microphone should never be mounted near the window or in a place where the road and ambient background noise would be substantially high (above 85 dB SPL).

Make all remaining wiring connections per wiring diagram. (See Figure 6-1b).
16 Chapter 7 Noise Sources 7.1 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.
Noise Sources 17 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. Electrical motors and generators also produce arcs.
18 Chapter 8 Operation of a Conventional Ignition System 8.1 Introduction To effectively reduce ignition interference in a vehicle, it is necessary to understand the operation of an automobile ignition system. Ignition is necessary in a gasoline engine to ignite the gasoline vapor and the air mixture in its cylinders. The system is made up of the battery, distributor, breaker points, coil, condenser, and spark plugs.
Operation of a Conventional Ignition System 19 The battery is connected to the primary winding of the coil through the ignition switch. The primary circuit is returned to the battery through the breaker points, which are bypassed by the condenser. The points are normally closed. As the cam shaft is rotated by the engine, it’s lobes or corners open and close the points in proper synchronization with the piston in each cylinder.
20 Chapter 9 Detection of Noise Sources 9.1 Noise Detection Procedure Detection of offending noise sources is the heart of noise suppression because, after the noise source is identified, the solution becomes obvious. A logical step-by-step procedure is basic to effective noise suppression. Use your available equipment to best advantage.
Detection of Noise Sources 9.2 21 Sources of Noise Some interference is due to geographic location. This interference does not need to be eliminated since it is possible for the vehicle to be moved away from the interfering noise source. Noise from power lines, fluorescent lights, and other vehicles (emitting high levels of radiated noise) are examples of noise which depend upon location. Make certain that you are not attempting to suppress noise in a vehicle while it is in a noisy location.
22 Chapter 10 Noise Reduction Techniques 10.1 General There are three basic ways to suppress noise. The first is the addition of resistance in circuits subject to ringing. This method is used for the ignition coil HV cable, spark plug wires, and spark plugs. The second is to filter noise from low voltage wiring using coaxial bypass capacitors. The third is to control static charge build-up using wipers for movable parts such as automobile hoods and trunk lids, or flexible bonding leads for fixed members.
Noise Reduction Techniques 23 10.2.3 Ignition Coil Interference This type of interference is characterized by a popping sound which is most noticeable when the engine is running slowly. To suppress the noise, connect a 0.1 µF coaxial capacitor (Motorola Part No. 0882571B02) from the battery side of the ignition coil to vehicle ground (see Figure Figure 10-1). This keeps the distributor noise from being conducted through the battery lead into the electrical system of the vehicle.
24 10.3 Noise Reduction Techniques Alternator This type of interference is characterized by a high-pitched whine which varies with engine speed. A 0.5 µF coaxial capacitor (Motorola Part No. 0882571B01) can be used to bypass the whine. For generators, the capacitors is connected in the armature lead. Never use a capacitor in the field lead. Use the field suppressor assembly supplied in the TLN5277 Noise Reduction Kit.
Noise Reduction Techniques 10.4 25 Voltage Regulator Noise This type of interference is characterized by erratic popping noises which change only slightly with changes in engine speed. The noise is generated by arcing in the vibrating breaker contacts of the voltage regulator. It can be suppressed by connecting a 0.5 µF coaxial capacitor (Motorola Part No. 0882571B01) in the battery and armature leads of the voltage regulator (see Figure 10-4).
26 Noise Reduction Techniques 3. Ignition Switch 4. Lamp bulbs (headlamps, tail lamps, dome lamps, etc.) 5. Accessory wiring (electrical fuel pump, electric windshield wipers, heater fan motor, window openers, etc.) 10.7 Ground Bonding If a vehicle is not properly bonded to ground, static charges can increase. This increase can cause noise from electrical arcing. This type of noise is suppressed by bonding the part using one-inch wide ground straps (keep them as short as possible).
