Kenwood TK-785, Instruction Manual

2

VARIOUS ELECTRONIC EQUIPMENT IN YOUR VEHICLE MAY MALFUNCTION IF THEY ARE
NOT PROPERLY PROTECTED FROM THE RADIO FREQUENCY ENERGY WHICH IS PRESENT
WHILE TRANSMITTING.  ELECTRONIC FUEL INJECTION, ANTI-SKID BRAKING, AND CRUISE
CONTROL SYSTEMS ARE TYPICAL EXAMPLES OF EQUIPMENT THAT MAY MALFUNCTION.  IF
YOUR VEHICLE CONTAINS SUCH EQUIPMENT, CONSULT THE DEALER FOR THE MAKE OF
VEHICLE AND ENLIST HIS AID IN DETERMINING IF THEY WILL PERFORM NORMALLY WHILE
TRANSMITTING.

Note:  The following preparation instructions are for use by your KENWOOD dealer, an authorized
KENWOOD service facility, or the factory.

Tools Required

Note:  Before installing the transceiver, always check how far the mounting screws will extend below the
mounting surface.  When drilling mounting holes, be careful not to damage vehicle wiring or parts.

The following tools are required for installing the transceiver:

•

6 mm (1/4 inch) or larger electric drill.

•

4.2 mm (5/32 inch) drill bit for the 5 x 16 mm self-tapping screws, and 3.2 mm
(1/8 inch) drill bit for the 4 x 16 mm self-tapping screws.

•

Circle cutters.

Power Cable Connection

THE TRANSCEIVER OPERATES IN 12 V NEGATIVE GROUND SYSTEMS ONLY!  CHECK THE
BATTERY POLARITY AND VOLTAGE OF THE VEHICLE BEFORE INSTALLING THE
TRANSCEIVER.

1 Check for an existing hole, conveniently located in the firewall, where the

power cable can be passed through.

•

If no hole exists, use a circle cutter to drill the firewall, then install a rubber
grommet.

2 Run the two power cable leads through the firewall and into the engine

compartment, from the passenger compartment.

3 Connect the red lead to the positive (+) battery terminal and the black lead to

the negative (–) battery terminal.

•

Locate the fuse as close to the battery as possible.

4 Coil and secure the surplus cable with a retaining band.

•

Be sure to leave enough slack in the cables so the transceiver can be removed for
servicing while keeping the power applied.
