TK-8150
GENERAL
INTRODUCTION
SCOPE OF THIS MANUAL
This manual is intended for use by experienced technicians familiar with similar types of commercial grade communications equipment. It contains all required service information for the equipment and is current as of this publication data. Changes which may occur after publication are covered by either Service Bulletins or Manual Revisions. These are issued as required.

3-2. Testing
The radio should be tested complete with all cabling and accessories as they will be connected in the final installation. Transmitter frequency, deviation, and power output should be checked, as should receiver sensitivity, squelch operation, and audio output. QT equipment operation should be verified.

4. PLANNING THE INSTALLATION 4-1. General
Inspect the vehicle and determine how and where the radio antenna and accessories will be mounted. Plan cable runs for protection against pinching or crushing wiring, and radio installation to prevent overheating.

ORDERING REPLACEMENT PARTS
When ordering replacement parts or equipment information, the full part identification number should be included. This applies to all parts : components, kits, and chassis. If the part number is not known, include the chassis or kit number of which it is a part, and a sufficient description of the required component for proper identification.

4-2. Antenna
The favored location for an antenna is in the center of a large, flat conductive area, usually at the roof center. The trunk lid is preferred, bond the trunk lid and vehicle chassis using ground straps to ensure the lid is at chassis ground.

PERSONNEL SAFETY
The following precautions are recommended for personnel safety : � DO NOT transmit if someone is within two feet (0.6 meter) of the antenna. � DO NOT transmit until all RF connectors are verified secure and any open connectors are properly terminated. � SHUT OFF and DO NOT operate this equipment near electrical blasting caps or in an explosive atmosphere. � All equipment should be properly grounded before powerup for safe operation. � This equipment should be serviced by a qualified technicians only.

4-3. Radio
The universal mount bracket allows the radio to be mounted in a variety of ways. Be sure the mounting surface is adequate to support the radio�s weight. Allow sufficient space around the radio for air cooling. Position the radio close enough to the vehicle operator to permit easy access to the controls when driving.

4-4. DC Power and wiring
1. This radio may be installed in negative ground electrical systems only. Reverse polarity will cause the cable fuse to blow. Check the vehicle ground polarity before installation to prevent wasted time and effort. 2. Connect the positive power lead directly to the vehicle battery positive terminal. Connecting the Positive lead to any other positive voltage source in the vehicle is not recommended.

PRE-INSTALLATION CONSIDERNATIONS
1. UNPACKING
Unpack the radio from its shipping container and check for accessory items. If any item is missing, please contact KENWOOD immediately.

CAUTION
2. LICENSING REQUIREMENTS
Federal regulations require a station license for each radio installation (mobile or base) be obtained by the equipment owner. The licensee is responsible for ensuring transmitter power, frequency, and deviation are within the limits permitted by the station license. Transmitter adjustments may be performed only by a licensed technician holding an FCC first, second or general class commercial radiotelephone operator�s license. There is no license required to install or operate the radio.

If DC power is to be controlled by the vehicle ignition switch, a switching relay should be used to switch the positive power lead. The vehicle ignition switch then controls DC to the relay coil.
3. Connect the ground lead directly to the battery negative terminal. 4. The cable provided with the radio is sufficient to handle the maximum radio current demand. If the cable must be extended, be sure the additional wire is sufficient for the current to be carried and length of the added lead.

3. PRE-INSTALLATION CHECKOUT 3-1. Introduction
Each radio is adjusted and tested before shipment. However, it is recommended that receiver and transmitter operation be checked for proper operation before installation.

5. INSTALLATION PLANNING � CONTROL STATIONS 5-1. Antenna system
Control station. The antenna system selection depends on many factors and is beyond the scope of this manual. Your KENWOOD dealer can help you select an antenna system that will best serve your particular needs.
