installation, consult your Kenwood dealer.
• If the unit does not seem to be working right,
try pressing the reset button first. If that does
not solve the problem, consult your Kenwood
dealer.
• Do not open the top or bottom covers of the
unit.
• Do not install the unit in a spot exposed to
direct sunlight or excessive heat or humidity.
Also avoid places with too much dust or the
possibility of water splashing.
• Do not set the removed faceplate or the
faceplate case in areas exposed to direct
sunlight, excessive heat or humidity. Also
avoid places with too much dust or the
possibility of water splashing.
• Do not subject the faceplate to excessive
shock, as it is a piece of precision equipment.
• To prevent deterioration, do not touch the
terminals of the unit or faceplate with your
fingers.
• When replacing a fuse, only use a new one
with the prescribed rating. Using a fuse with
the wrong rating may cause your unit to
malfunction.
• To prevent short circuits when replacing a
fuse, first disconnect the wiring harness.
• Do not place any object between the
faceplate and the unit.
• When extending the battery or ground.

• If the unit starts to emit smoke or strange
smells, turn off the power immediately and
consult your Kenwood dealer.
• Be careful not to drop the unit or subject it to
strong shock.

Cleaning the Faceplate Terminals
If the terminals on the unit or faceplate get
dirty, wipe them with a dry, soft cloth.
Cleaning the Unit
If the front panel gets dirty, turn off the
power and wipe the panel with a dry silicon
cloth or soft cloth.
The unit may break or crack because it
contains glass parts.
2CAUTION
Do not wipe the panel with a stiff cloth or a
cloth dampened by volatile solvents such as
paint thinner and alcohol. They can scratch
the surface of the panel and/or cause the
indicator letters to peel off.
• During installation, do not use any screws
except for the ones provided. The use of
improper screws might result in damage to
the main unit.

Troubleshooting Guide
What might appear to be a malfunction in your unit may just be the result of slight misoperation or miswiring. Before
calling service, first check the following table for possible problems.
PROBLEM
POSSIBLE CAUSE
SOLUTION
The power is not turned on.
The fuse has blown.
After checking for short circuits in the cables, replace the
fuse with one having the same rating.
Egnlish
The power control cable are connected incorrectly.
Connect the same cable to the centre unit.
Reset the fader and/or balance settings.
No sound can be heard, or the
volume is low.
The fader and/or balance settings are set all the way to
one side.
The input/output cables or wiring harness are connected
incorrectly.
Connect the input/output cable or wiring harness correctly.
See "Connections".
The main unit panel is open.
The fader is set to one side.
Close the panel.
Adjust the fader.
The front or rear speaker does
not output sound.
Nothing happens when the
buttons are pressed.
The computer chip in the unit is not functioning normally.
Press the reset button on the unit (see page 3).
The 16kHz indicator of the
spectrum analyzer does not
light.
In particular, the indicator may not light for a cassette
tape because the 16kHz level of the source is low.
If it lights when you play a compact disc, there is no
problem.
Hiss noise is generated.
The graphic equalizer level is too high.
Set the graphic equalizer level to a correct level.
The power amp input sensitivity setting is wrong.
If the front and rear level gain is set to "HIGH", set the power
amp input sensitivity to 4V.
The sound is distorted.
The main unit input sensitivity setting is wrong.
Match the main unit input sensitivity setting to the output
voltage of the centre unit (see page 7).
