1 INTRODUCTION

This document provides guidelines for the installation of BK Radio’s KNG
Mobile radios. Failure to adhere to these guidelines may result in diminished
performance or physical damage to the radio. Installations should only be
performed by RELM authorized dealers or technicians.

2 GENERAL

Plan your installation carefully. Locate the radio and microphone within easy
reach, giving the operator a clear view of the display.

When selecting a mounting position for your KNG Mobile, look for a fl at surface
that will provide adequate space for the radio and cable attachments. For dash
mount installation clearance of at least 12” x 7 1/2” is recommended.

Do not locate the radio, microphone or speaker in a position that interferes with
safe operation of the vehicle or equipment.

It is recommended to run all necessary cables or wires prior to installation of a
radio or remote control head.

4 HARDWARE MOUNTING

4.1 WIRING

Once the equipment location is chosen, determine the best routing for cables
and wires to connect the system. Use a rubber grommet to protect the wires
when passing through sheet metal. Avoid any route that subjects the wire to
pinching, cutting, or high heat from the engine or other vehicle components.
Avoid splicing into old or existing power lines.

The radio must be used with a 12 volt, NEGATIVE GROUND electrical system.

Carefully route the A+ wiring assembly from the radio connection to the 1.
battery compartment.

Using the supplied barrel crimp, attach the fuse holder (Item 4) as close to 2.
the battery as possible as shown in fi gure 1.
(NOTE: Only use 30 Amp rated fuses on the A+ line for dash mount/radio
core power cord. Only use 7 1/2 Amp rated fuse on the A+ line for remote
head power cords.)

Connect the red power lead (with fuse assembly) to the vehicles POSITIVE 3.
battery terminal. Using other positive voltage points is not recommended.

Connect the black lead to a good ground point on the chassis. Connection 4.
to the negative battery terminal is not recommended.
