Safety precautions
To prevent injury and/or fire, take the
following precautions:
• Insert the unit all the way until it is fully
locked in place. Otherwise it may fly out of
place during collisions and other jolts.
• When extending the ignition, battery or
ground cables, make sure to use automotivegrade cables or other cables with an area of
0.75mm2(AWG18) or more to prevent cable
deterioration and damage to the cable coating.
• To prevent short circuits, never put or leave
any metallic objects (e.g., coins or metal
tools) inside the unit.
• 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.
The unit may break or crack because it contains glass parts.
• Do not touch the liquid crystal fluid if the LCD
is damaged or broken due to shock. The liquid crystal fluid may be dangerous to your
health or even fatal.
If the liquid crystal fluid from the LCD contacts your body or clothing, wash it off with
soap immediately.
2WARNING
To prevent damage to the machine,
take the following precautions:
• Make sure to ground the unit to a negative
12V DC power supply.
• 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.
• 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.
2CAUTION
• If you experience problems during 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.
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.
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.
Cleaning the Faceplate Terminals
If the terminals on the unit or faceplate get
dirty, wipe them with a dry, soft cloth.

Cleaning the Tape Head
After you have used the tape player many times over a long period,
magnetic powder from the tapes and dust accumulates on the tape
head, causing noise and a deterioration in sound quality. Clean the
tape head using a cleaning tape or cleaning kit designed for use in car
audio systems.
Handling Cassette Tapes
• Do not play a cassette whose tape has gone slack. In such a case,
wind it tight using a pencil or the like in one of the spools. Playing
slack cassette tapes can result in the tape tangling around the capstan and/or pinch rollers, causing trouble.
• Do not play a deformed cassette or one whose label is starting to
come off, as it can cause the unit to malfunction.
• Do not leave tapes in hot places, such as above the fascia panel
(dashboard) and other spots exposed to direct sunlight, or near
heater outlets. They can deform the cassette.
• Avoid using extremely long cassette tapes, such as 100-minute-long
tapes. Such tapes are very thin, and can tangle easily around the
pinch rollers or other parts inside the unit, causing unit failure.
• Remove a cassette tape from the unit when not listening to it for a
whilst. If you leave a tape in the unit too long, it may stick to the tape
head and cause unit malfunction.
