Hints for correct and safe operation

Remove the magazine from the unit when it is
not being used during hot weather and the CD
changer is not used for long periods of time.

When using 8 cm CDs, use a 8 cm CD adapter
which conforms to CD standards and be sure
to load the CDs in trays No. 1, 3, and 5
(gray trays). Loading CDs into other trays will
result in a malfunction.

This CD Changer is designed to be operated
only on +12 volt DC negative ground systems.
The unit cannot be used on +24 volt or posi­tive ground systems.

At very high or very low temperatures it may
happen that the radio does not function pro­perly. An overload protection circuit responds
if the temperature reaches a specified limit
value. The unit then switches automatically
off. In this case, open the car window or
switch on the heating (air-conditioning) and
wait until the temperature meets again the
admissible operating conditions.

Condensation

Moisture can condense on the laser lens of
the CD changer during rainy and humid days,
or right after the heater is turned on in the car.
If this should happen the unit will not operate
correctly. To remedy the situation, remove the
magazine from the unit and wait approximate­ly one hour. During this time the moisture will
evaporate and the unit will operate normally.

How to use the magazine

Loading a disc

Pick the tab on the magazine’s disc tray and
pull out only one of the trays.

Place the disc on the tray with its play surface
facing up (label surface facing down).

– Each tray can accommodate only one disc.
– “E-07” appears about 8 seconds if the disc

is placed upside down.

Press the tab on the disc tray to store the tray
back in the magazine.

– Up to six discs can be loaded.
– Use the 8 cm CD adapter for 8 cm discs.

(See page 4).

Installing the magazine

Slide the door toward the right.

First check that the magazine with the discs
inside has its top side facing up and that it is
pointed in the right direction for installation.
Push it in until it clicks into place, indicating
that it is now locked.

– When the magazine is used for the first

time, it will not lock into place unless the
power supply has been connected.

Ejecting the magazine

The magazine is ejected by pressing the eject
button (

ə

).

Notes:
Be absolutely sure to close the door after
having inserted or ejected the magazine. Dust
or dirt finding its way inside may cause mal­functioning of the unit.

Precautions for handling discs

With 8 cm CDs

When using 8 cm CDs, use a 8 cm CD adapter
which conforms to CD standards and be sure
to load the CDs in trays No. 1, 3, and 5
(gray trays). Loading CDs into other trays will
result in a malfunction.

Be sure to attach the disc properly to the cat­ches provided on the adapter.

If the disc is not attached correctly, it may
come free inside the magazine or play mecha­nism, rendering the unit inoperable.

– The disc is not played even when it is

loaded.

– Operation changes to the next disc before

the first disc has a chance to be played.

– The same disc is played over and over

again.

– The designated disc is not played.

These symptoms occur when there are burrs
on the center hole or outside circumference of
the disc and, as a result, the disc has not been
loaded properly or the disc catches on some­thing inside the magazine.

In cases like these, remove the burrs using a
ball-point pen or similar implement, as shown
in the figure below.

Storing the 8 cm CD adapters

Under no circumstances must an empty
8 cm CD adapter be loaded inside the
magazine.

If this warning is not heeded, the adapter will
remain inside the mechanism, rendering the
unit inoperable.

WARNING

Although protective film is being marketed as
CD accessories, use of these products will
result in malfunctions and should absolutely
be avoided.

With new discs

The symptoms described below sometimes
occur when new discs are used.

Before installing the unit

Transport lock screws

The mechanism in the CD changer is “locked”
into place during shipment by the transport
screws.
Be sure to remove the screws prior to installa­tion.

Caution:
After removing the transport lock screws,
place the supplied seals over the screw holes.
These seals are used to keep dust, which
could cause a malfunction, out of the unit.

Installation and wiring precautions

To prevent a short-circuit:
– Be sure to turn off the ignition and remove

the negative (–) battery cable prior to instal­lation.

Note:
If the changer is to be installed in a car that is
equipped with an on-board drive or navigation
computer, do not disconnect the battery cable.
If the cable is disconnected, the computer
memory may be lost. Under these conditions,
use extra caution to avoid causing a short
circuit during installation.

Do not install the unit in the following
locations:
– Locations exposed to direct sunlight.
– Where hot air is discharged from the car

heater.

– When proper installation is not possible and

where a great deal of vibration is generated.

– Be sure to use the supplied brackets and

screws.

– When installing the unit, do not use any

screws that are part of the brake or steering
system.

This unit cannot be installed in any way except
that which is authorized (on its side, on its
end, at a 45° angle or suspended). Installing it
with its side facing down or upside down can
cause malfunctioning.

Before installing the unit Wiring

Position of the built-in anti-vibration
board

This unit can be installed horizontally
(suspended), vertically, and at a 45° angle.
Once the installation position has been deci­ded, it's necessary to set the position of the
built-in anti-vibration board inside the unit.
Please do this before perfoming the procedu­re listed below. Vibration may cause the disc
to skip if the unit is used before properly
setting the anti-vibration board.
– At the time of shipping, the built-in anti-

vibration board is set for horizontal installa­tion “H”.

– The are built-in anti-vibration boards on

both the left and right sides.

– Set the anti-vibration board position with a

screwdriver before attaching the brackets.

For use when unit is installed horizontally
or suspended:

Confirm that the built-in anti-vibration board
is set to position “H”.

For use when unit is installed vertically:

The built-in anti-vibration board should be set
to position “V”.

For use when unit is installed at a 45° angle:

The built-in anti-vibration board should be set
to position “45°”.

Connect the CD changer with the cable
supplied to a car radio equipped accordingly
(see operating instructions):

Handling the discs

Dirt, dust, scratches and warpage cause
sound skips during playback and a deteriora­tion of sound quality. How to take care of your
discs:

1. Use compact discs that have the mark
shown on the right.

2. Fingerprints and dust should be carefully

wiped off the disc’s signal surface (glossy
side) with a soft cloth. Unlike conventional
records, the compact disc has no grooves
to collect dust and microscopic debris, so
gently wiping with a soft cloth should
remove most particles. Wipe in a straight
motion from the inside to the outside of the
disc. Small dust particles or light stains will
have absolutely no effect on reproduction
quality.

3. Never use such chemicals as record
sprays, antistatic sprays or fluid, benzine or
thinner to clean compact discs. Such
chemicals would irreparably damage the
disc’s plastic surface.

ʀ

4. Discs should be put back in their cases
after use to avoid serious scratches that
could cause sound skip.

5. Do not expose discs to direct sunlight, high
humidity, or high temperatures for exten­ded periods of time. Long exposure to high
temperatures can warp the disc.

6. Do not stick paper or write anything with a
ball-point pen on the disc surface.

Troubleshooting

Problems which arise because of a bad mani­pulation of the set or incorrect connections
are often wrongly considered to be a malfunc­tion of the set. For this reason, the following
table is provided to help you. If the measures
listed in the table are not successful, please
contact your specialized dealer.

Note any fault messages in the display of your
