vi Safety and General Information IMPORTANT INFORMATION ON SAFE AND EFFICIENT OPERATION READ THIS INFORMATION BEFORE USING YOUR MOTOROLA TWO-WAY RADIO The information provided in this document supersedes the general safety information contained in documentation published prior to June 2001. Radio Frequency (RF) Operational Characteristics To transmit (talk) you must push the Push-To-Talk button; to receive (listen) you must release the Push-To-Talk button.
Safety and General Information • vii Hearing Aids Some digital wireless radios may interfere with some hearing aids. In the event of such interference, you may want to consult your hearing aid manufacturer to discuss alternatives. • Other Medical Devices If you use any other personal medical device, consult the manufacturer of your device to determine if it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this information.
viii Safety and General Information Mobile Radio Operation and EME Exposure To assure optimal radio performance and that human exposure to radio frequency electromagnetic energy is within the guidelines referenced in this document, transmit only when people outside the vehicle are at least the minimum lateral distance away from a properly installed, externally-mounted antenna. The table below lists the minimum and lateral distance for several different ranges of rated radio power.
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. Some models may be mounted in the car radio cut-out (using the required RLN4781_ mounting kit). 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.

19 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.
20 Noise Sources 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.
21 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.
22 Operation of a Conventional Ignition System 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, its lobes or corners open and close the points in proper synchronization with the piston in each cylinder.
23 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.
24 Detection of Noise Sources Ignition Switch 3 1 Ignition Coil Resistive Wire (Note 2) 6 Resistor Spark Plugs (Note 2) Battery Distributor Breaker Points Notes: 1. Noise reduction can only be achieved if components are grounded properly. Be sure that all the capacitors and the generator field suppressor assembly are grounded properly. This may require bonding straps for proper bypass capacitor effectiveness. 2. Items not supplied in kit. See auto parts dealer.
Detection of Noise Sources 9.2 25 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 depends upon location. Make certain that you are not attempting to suppress noise in a vehicle while it is in a noisy location.
26 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 27 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 10-1). This keeps the distributor noise from being conducted through the battery lead into the electrical system of the vehicle.
28 10.3 Noise Reduction Techniques 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 (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 TLN6252 Noise Reduction Kit.
Noise Reduction Techniques 10.4 29 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).
30 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).
