Read this information before using your radio. SAFE AND EFFICIENT OPERATION OF MOTOROLA TWO-WAY RADIOS This document provides information and instructions for the safe and efficient operation of Motorola Portable and Mobile Two-Way Radios. The information provided in this document supersedes the general safety information contained in user guides published prior to 1 January 1998. - Page 4 WARNING: Disruption of the anti-skid/anti-lock braking system by the radio transmitter may result in unexpected vehicle motion. For vehicles with electronic anti-lock/anti-skid brakes, Motorola recommends the following radio installation precautions and vehicle braking system test procedures to ensure that the radio, when transmitting, does not interfere with the operation of the vehicle braking system.

5. Ensure that there is a minimum of two vehicle lengths between the front of the vehicle and any object in the vehicle’s forward path. Then, set the vehicle transmission selector to DRIVE. Press the brake pedal just far enough to stop the vehicle motion completely. Key the radio transmitter. Verify that the vehicle does not start to move while NOT speaking into the microphone. -

Page 9: Chapter 1 Installation
Chapter 1 INSTALLATION Introduction General Information There are two methods of installing your mobile radio: Using the direct mounting trunnion and power cables supplied with a standard radio package. Mounted in the car radio cut-out (using the required GLN7320_ mounting kit, per ISO7736). An accessory connector on the rear of the radio (see Figure 1-4 Connections to the Back of Radio) enables you to attach different accessories required for the installation. -
Page 10: Power Cable Installation Procedure
INSTALLATION The following table lists power cables available for this radio: Table 1-1 Power Cables Number Description Rating HKN4137_ Low power cable to battery 1-25W; 15A fuse; 14 AWG 3m HKN4191_ High Power Cable to battery 25-45W; 20A fuse; 12 AWG 3m Power Cable Installation Procedure Begin the power cable installation as follows: Determine a routing plan, keeping in mind where the radio is to be mounted. - Page 11 DC Power Cable Installation Connect the black lead of the power cable to the nearest vehicle chassis ground point (using the provided ring lug if necessary). Shorten the black lead to remove any excess cable. (See Figure 1-2 Power Cable Assembly.) NOTE Locate a good vehicle ground point.

Page 12: Trunnion Installation
INSTALLATION Trunnion Installation Planning the Mounting Trunnion Installation The standard mounting trunnion allows the radio to be mounted to a variety of surfaces. Ensure the surface can support the weight of the radio. Although the trunnion can be mounted to a plastic dashboard, it is recommended that the mounting screws be located so they penetrate the supporting metal frame of the dashboard. -
Page 13: Control Head Mounting Position
Antenna Installation Control Head Mounting Position The control head is designed to be removed from the housing and turned to any position within a 180° radius. This provides multiple mounting options for the radio. For example, the radio may be mounted on either side of the vehicle transmission tunnel to facilitate the safest and most ergonomically ideal position. -
Page 14: Selecting An Antenna Site
This minimizes radio interference to the modulator box from the radio. Motorola offers a glass-mount antenna as an accessory. It is usually mounted on the rear window. This antenna should be placed as high as possible on the vehicle. Ensure that a rear-window defogger element does not touch the inductive “button”... -

Page 25: Reducing Noise Interference
Chapter 2 REDUCING NOISE INTERFERENCE 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. -
Page 26: Conducted Noise
REDUCING NOISE INTERFERENCE When a spark discharge or arc takes place through air, energy is radiated at frequencies from a few kilohertz to hundreds of megahertz. This spurious radiation may have some energy radiated at a frequency near or even identical to the desired radio signal. The standard receiver may be unable to distinguish between the two signals (desired and noise). -
Page 27: Induced Noise
Operation of a Conventional Ignition System Induced Noise Induced noise enters the radio through the proximity of radio wiring to other wiring in the vehicle. Electrical currents through the standard vehicular wiring can induce undesirable noise signals into the radio cabling. Communication is degraded simply because the wiring provides a transformer- type coupling action without any actual physical connection. - Page 28 REDUCING NOISE INTERFERENCE HV Lead Distributor Ignition Breaker Coil Ignition Points Switch Spark plug leads Spark Battery Plugs Condenser Rotor Gap Ignition Breaker Coil Ignition Lead Inductance Points Switch Stray Capacitance Spark Plug Gap Battery Condenser FL0830261-O Figure 2-2 Typical Vehicular Ignition System, Simplified Schematic Diagram The battery is connected to the primary winding of the coil through the ignition switch.

Page 31: Sources Of Noise
Noise Reduction Techniques 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. -
Page 32: Ignition System 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 2-5 Ignition Coil Noise Suppression). -
Page 33: 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. - Page 34 2-10 REDUCING NOISE INTERFERENCE Step 1. Step 3. Mount Capacitor Connect wire lead to capacitor (0.5µF Coaxial Type) using lockwasher and nut. under generator ground screw. Step 4. Connect capacitor lead to armature post. Caution: Do not connect capacitor to field teminal. Step 2.

Page 35: Voltage Regulator Noise
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 2-8 Voltage Regulator Noise Suppression). -
Page 36: Ground Bonding
Wheel Static Road friction can cause static build-up on the front wheels. Suppress noise from this source using wheel static collector rings (Motorola Part No. 0100534254 regular type - 0100653173 small type). Ground Bonding If a vehicle is not properly bonded to ground, static charges can increase. This increase can cause noise from electrical arcing.
