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 electrostat-
ic 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 fl exible 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.
If the optical pick-up block is defective, please replace the whole 
optical pick-up block.
Never turn the semi-fi xed resistor located at the side of optical 
pick-up block.
EXTENSION  CABLE  AND  SERVICE  POSITION
When repairing or servicing this set, connect the jig (extension 
cable) as shown below.
•  Connect the MAIN board (CNP501) and the SERVO board 
(CN2) with the extension cable (Part No. J-2502-076-1).
NOTE  THE  IC500  AND  IC510  ON  THE  IT  BOARD  
REPLACING
When IC500 and IC510 on the IT board are damaged, exchange 
the new IT board for the IT board which IC damaged.

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 fl ow) 
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.

REPLACING  THE  LITHIUM  BATTERY  OF  THE  CARD  
REMOTE  COMMANDER
Under normal conditions, the battery will last
approximately 1 year. (The service life may be
shorter, depending on the conditions of use.)
When the battery becomes weak, the range of the
card remote commander becomes shorter. Replace
the battery with a new CR2025 lithium battery. Use
of any other battery may present a risk of fire or
explosion.
Notes on the lithium battery
• Keep the lithium battery out of the reach of children.
Should the battery be swallowed, immediately
consult a doctor.
• Wipe the battery with a dry cloth to assure a good
contact.
• Be sure to observe the correct polarity when
installing the battery.
• Do not hold the battery with metallic tweezers,
otherwise a short-circuit may occur.

ɠ  To AMP REMOTE IN of an optional power 
amplifi er
This connection is only for amplifi ers. Connecting any other 
system may damage the unit.
ɡ  To the interface cable of a car telephone
ɢ  To a car’s illumination signal
Be sure to connect the black ground lead to a metal surface 
of the car fi rst.
ɣ  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 ground lead to a metal 
surface of the car fi rst.
  When your car has a built-in FM/AM antenna in the rear/
side glass, see “Notes on the control and power supply 
leads.”
ɤ  To the +12 V power terminal which is 
energized at all times
Be sure to connect the black ground lead to a metal surface 
of the car fi rst.
Notes on the control and power supply leads
  The power antenna control lead (blue) supplies +12 V DC 
when you 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 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
  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 (–) 
terminal of the speaker.
  Do not attempt to connect the speakers in parallel.
  Connect only passive speakers. Connecting active speakers 
(with built-in amplifi ers) to the speaker terminals may damage 
the unit.
  To avoid a malfunction, do not use the built-in speaker leads 
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 leads to each other.
Note on connection
If speaker and amplifi er are not connected correctly, “Failure” 
appears in the display. In this case, make sure the speaker and 
amplifi er are connected correctly.
Connection example
Notes (
ǵ-A)
  Be sure to connect the ground lead before connecting the 
amplifi er.
  The alarm will only sound if the built-in amplifi er is used.
Tip (
ǵ-B- )
For connecting two or more CD/MD changers, the source 
selector XA-C40 (not supplied) is necessary.
Connection diagram
ɞ  To a metal surface of the car
First connect the black ground lead, then connect the 
orange/white striped, yellow, and red power input leads.
ɟ  To the power antenna control lead or power 
supply lead of antenna booster amplifi er
Notes
  It is not necessary to connect this lead if there is no power 
antenna or antenna booster, or with a manually-operated 
telescopic antenna.
  When your car has a built-in FM/AM antenna in the rear/
side glass, see “Notes on the control and power supply 
leads.”
