SECTION 1

SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down 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.

NOTES ON LASER DIODE EMISSION CHECK

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

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 viscou-s (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.

1 Car Systems Connections

Refer also to the documentation for all other components in the system.

Also see “Connecting Information” on page 6.

•Components listed here except for supplied accessories are available separately. When connecting such
components, be sure to also refer to their documentation.
For specifications and other information on separately available components, contact your dealer.

Prevention of accidents caused by short-circuits

To prevent the risk of accidents caused by short-circuits, connect the power supply leads (red and yellow)
only after all other wiring has been completed, and only with the ignition key in the OFF position.
Otherwise, accidental short-circuiting can lead to electric shock and to serious damage.

When a fuse has blown, check the wiring and locate the cause of the problem before replacing the fuse.
When replacing the fuse, be sure to use only a fuse of the same rating (ampere rating). Using a different
fuse or bridging the contacts with wire is highly dangerous and can lead to serious damage.

Make sure to connect all of the following leads.

Otherwise there is a risk of electric shock, damage to the equipment, or malfunction.

•Connect purple/white lead to back lamp lead of car.

•Connect orange/white lead to illumination signal lead of car.

•Connect light green lead to parking brake switch lead of car.

•Connect yellow lead to battery power supply of car.

•Connect red lead to accessory power supply of car.

•Connect black lead to metal point on car chassis.

* Do not mix up the yellow and red leads, as this will cause the memory contents to be lost.

Observe the following precautions.

Otherwise there is a risk of electric shock, damage to the equipment, or malfunction.

•Cover unused connectors with electrician’s tape to prevent accidental contact.

• Route FM/AM antenna cable, bus cable, RCA interconnects, and power supply leads as far apart from
each other as possible, to prevent noise interference.

•Always grasp the connector and do not pull the cable when disconnecting the bus cable or other cables.
Otherwise the cable may become detached.

Notes on the control and power supply leads

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

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

•A power antenna 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 of

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 ground lead of this unit to the negative E 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 shar
common negative E lead for the right and left speakers.

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