NOTES ON HANDLING THE OPTICAL PICK­UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro­static breakdown because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body .
During repair, pay attention to electrostatic breakdown and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.

FOR CD

NOTES ON LASER DIODE EMISSION CHECK

The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emis­sion, observe from more than 30 cm away from the objectiv e lens.

FOR MD

NOTES ON LASER DIODE EMISSION CHECK

Never look into the laser diode emission from right avove when
checking it for adustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
(KMS-241C)

The laser diode in the optical pick-up block may suffer electro­static break-down easily. When handling it, perform soldering
bridge to the laser-tap on the flexible board. Also perform
m easur es against electrostatic break-down suff iciently before the
operation. The flexible board is easily damaged and should be
handled with care.

Notes on chip component replacement

•Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.

Notes on CD-R/CD-RW discs

•You can pl ay CD-Rs (recordabl e CD s)/CD­RWs (rewritable CDs) designed for audio use
on this unit.
Look for these marks to distinguish CD-Rs/
CD-RWs for audio use.

These marks denote that a disc is not for audi o
use.

•Some CD-Rs/CD-RWs (depending on the
equipment used for its r ecording or the
condition of the disc) m ay not play on this unit.

•You cannot play a CD-R/a CD-RW that is not
finalized*.

*

A process necessary for a recorded CD-R/CD-RW
disc to be played on the audio CD player.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead­free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 ˚C higher than

ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350 ˚C .
Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

• Strong viscosity

Unleaded solder is more viscous (sticky , less prone to flow) than
ordinary solder so use caution not to let solder bridges occur
such as on IC pins, etc.

• Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.

Flexible Circuit Board Repairing

•Keep the temperature of the soldering iron around 270 ˚C dur­ing repairing.

• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).

• Be careful not to apply force on the conductor when soldering
or unsoldering.

Cautions

• This unit is designed for negative earth 12 V
DC operation only.

• Do not get the wires under a screw, or caught
in moving parts (e.g. seat railing).

• Before making connections, turn the car
ignition off to avoid short circuits.

• Connect the yellow and red power input leads
only after all other leads have been connected.

• Run all earth wires to a common earth

point.

• Be sure to insulate any loose unconnected
wires with electrical tape for safety.

Notes on the power supply cord (yellow)

• When connecting this unit in combination with
other stereo components, the connected car
circuit’s rating must be higher than the sum of
each component’s fuse.

• When no car circuits are rated high enough,
connect the unit directly to the battery.

Parts Iist (1)

The numbers in the list are keyed to those in the
instructions.

Connection example (2)

Notes

(2-A)

• Be sure to connect the earth lead before
connecting the amplifier.

• If you connect an optional power amplifier and do
not use the built-in amplifier, the beep sound will
be deactivated.

Tip

(2-B- )

For connecting two or more changers, the source
selector XA-C30 (optional) is necessary.

Connection diagram (3)

When inserting each connector, be sure to insert
securely, as vibration through driving may
cause a poor connection.

1

To a metal surface of the car

Make sure to connect the black earth lead first of
all, then proceed with connection steps 2-7.
Check the black earth lead is connected properly,
before connecting the orange/white striped lead,
yellow and red power input leads.

2

To AMP REMOTE IN of an optional power
amplifier

This connection is only for amplifiers. Connecting
any other system may damage the unit.

3

To the power aerial control lead or power supply

lead of aerial booster amplifier

Notes

•It is not necessary to connect this lead if there
is no power aerial or aerial booster, or with a
manually-operated telescopic aerial.

•When your car has a built-in FM/AM aerial in
the rear/side glass, see “Notes on the control
and power supply leads.”

4

To the interface cable of a car telephone

5

To a car’s illumination signal

Be sure to connect the black earth lead to it first.

6

To the +12 V power terminal which is energized
in the accessory position of the ignition key
switch

Notes

• If there is no accessory position, connect to the
+12 V power (battery) terminal which is
energized at all times.
Be sure to connect the black earth lead to it
first.

•When your car has a built-in FM/AM aerial in
the rear/side glass, see “Notes on the control
and power supply leads.”

7

To the +12 V power terminal which is energized
at all times

Be sure to connect the black earth lead to it first.

Notes on the control and power supply leads

• The power aerial control lead (blue) supplies +12 V
DC when you turn on the tuner.

•When your car has built-in FM/AM aerial in the
rear/side glass, connect the power aerial control
lead (blue) or the accessory power input lead (red)
to the power terminal of the existing aerial
booster. For details, consult your dealer.

•A power aerial without relay box cannot be used
with this unit.

Memory hold connection

When the yellow power input lead is connected,
power will always be supplied to the memory circuit
even when the ignition key is turned off.

Notes on speaker connection

• Before connecting the speakers, turn the unit off.

• Use speakers with an impedance of 4 to 8 ohms,
and with adequate power handling capacities to
avoid its damage.

• Do not connect the speaker terminals to the car
chassis, or connect the terminals of the right
speakers with those of the left speaker.

• Do not connect the earth lead of this unit to the
negative (–) terminal of the speaker.

•Do not attempt to connect the speakers in parallel.

• Connect only passive speakers. Connecting active
speakers (with built-in amplifiers) to the speaker
terminals may damage the unit.

• To avoid a malfunction, do not use the built-in
speaker wires installed in your car if the unit shares
a common negative (–) lead for the right and left
speakers.

• Do not connect the unit’s speaker cords to each
other.

Precautions

• Choose the installation location carefully so
that the unit will not interfere with normal
driving operations.

• Avoid installing the unit in areas subject to
dust, dirt, excessive vibration, or high
temperatures, such as in direct sunlight or near
heater ducts.

• Use only the supplied mounting hardware for
a safe and secure installation.

To open/close the front panel smoothly, to insert/

eject a disc easily, and especially to drive safely, a
certain distance between the front panel and the
shift lever is necessary. The necessary distance
differs, depending on the shift lever position of
your car. Before installing the unit, choose the
installation location carefully so that you can
drive safely.
