SERVICE NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP 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.

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 pick­up block. Therefore, when checking the laser diode emission, ob­serve from more than 30 cm away from the objective lens.

Notes on Chip Component Replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.

If the optical pick-up block is defective, please replace the whole
optical pick-up block.
Never turn the semi-fixed resistor located at the side of optical
pick-up block.

Notes on CD-Rs (recordable CDs)/CD-RWs (rewritable
CDs)

This unit can play the following discs:

Type of discs Label on the disc

Audio CD

MP3 files

• Some CD-Rs/CD-RWs (depending on the equipment used for

its recording or the condition of the disc) may not play on this
unit.

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

• You can play MP3 files recorded on CD-ROMs, CD-Rs, and

CD-RWs.

• A CD-R/CD-RW to which a session can be added can be played.

UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the lead
free 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.

∗ A process necessary for a recorded CD-R/CD-RW disc to be

played on the audio CD player.

EXTENSION CABLE AND SERVICE POSITION

When repairing or servicing this set, connect the jig (extension cable)
as shown below.

• Connect the MAIN board (CN751) and the SERVO board (CN2)
with the extension cable (Part No. J-2502-076-1).

Connection diagram (3)

A

To AMP REMOTE IN of an optional power amplifier

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

B

To the interface cable of a car telephone

Warning

If you have a power aerial without a relay box, connecting this unit
with the supplied power connecting lead 7 may damage the aerial.

Notes on the control leads

• The power aerial control lead (blue) supplies +12 V DC when you
turn on the tuner, or when you activate the AF (Alternative
Frequency) or TA (Traffic Announcement) function.

•When your car has built-in FM/MW/LW 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 a 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 switch is
turned off.

Notes on speaker connection
