4. PLANNING THE INSTALLATION

4-1. General

Inspect the vehicle and determine how and where the ra-
dio antenna and accessories will be mounted.
Plan cable runs for protection against pinching or crushing
wiring, and radio installation to prevent overheating.

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.

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 rec-
ommended.
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.

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.

5-2. Radio location

Select a convenient location for your control station radio
which is as close as practical to the antenna cable entry point.
Secondly, use your system’s power supply (which supplies
the voltage and current required for your system). Make sure
sufficient air can flow around the radio and power supply to
allow adequate cooling.
GENERAL

SERVICE

This radio is designed for easy servicing. Refer to the
schematic diagrams, printed circuit board views, and align-
ment procedures contained in this manual.

NOTE

•If you do not intend to use the speaker 3.5-mm jack and
the D-sub 25-pin connector, fit the supplied speaker-jack
cap and D-sub cap to stop dust and sand from getting in.
•If the transceiver is turned ON or OFF when the power-on/
off status message is enabled, the transceiver sends the
status.
