• 

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

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)

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.

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
The laser beam on this model is concentrated so as to be focused 
on the disc refl ective 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.

RELEASING  THE  DISC  TRAY  LOCK
The disc tray lock function for the antitheft of an demonstration 
disc in the store is equipped.

Releasing Procedure:

seconds).

4.  The message “UNLOCKED” is displayed and the disc tray is 

unlocked.

Note: When 

“

LOCKED

”

 is displayed, the slot lock is not released by 

turning power on/off with the

 [

?/1

]

 button.

NOTE  THE  HANDLING  OF  HDD
1.  Note The Transported
Do not give set the high impact when you transport this set. HDD 
might be damaged by the impact.

2.  Note The Repairing
Do not move the set for state power on, and for at least 30 seconds 
after the set is power off. HDD might be damaged by the impact.

NOTE  THE  IC5  AND  IC13  ON  THE  USB  MICOM  
BOARD  REPLACING
IC5 and IC13 on the USB MICOM board cannot exchange with 
single. When these parts on the USB MICOM board are damaged, 
exchange the entire mounted board.

NOTE  THE  DISASSEMBLY  OF  USB  CONNECTOR  
BOARD
USB CONNECTOR board and HDD LED (A)/(B) board connec-
tion part are damaged easily. Note the printed pattern may peel, 
remove carefully.

NOTE  THE  IC202  ON  THE  MAIN  BOARD  
REPLACING
Excecute the following procedures immediately after the IC202 on 
the MAIN board is exchanged, and the cold reset is executed.

Procedure:
1.  Press the [

?/1

] button to turn the power on.

2.  Press the [TUNER/BAND] button to select TUNER (FM) 

function.

3.  Press the [TUNING MODE] button on the remote commander 

to preset menu displayed.

4.  Press the [M]/[m] buttons to select “FM2 88.00 MHz”.

•  It is backup in the customer in preparation for the HDD exchange as for the tune recorded to HDD beforehand.
•  Note that all recorded tunes are deleted when “Factory Reset" is done.

2. Common Check
Procedure:
1.  Execute “COLD RESET” (Refer to page 13) after confi rming the symptom.
2. Confi rm the installation of HDD.
3. Confi rm the power supply to HDD.
4.   Confi rm the state to HDD of the connecting cable and the connector.

4.  Processing After HDD Is Replaced
Procedure:
1. Confi rm the execution of “HDD Writing/Reading Test” (Refer to page 14), and not becoming NG.
2.  Execute “CDDB Version Display” (Refer to page 14), and confi rm the CDDB version is 989 (South American model) or 988(Except 

South American model). 

3. Confi rm the tune can be recorded from CD to HDD, and the tune be reproduced normally.
4.   Execute “Initialization Mode For Factory” (Refer to page 14) at the end.

: HDD doesn't rotate.

The set symptom  : HDD doesn't rotate.

Correspondence : If the power supply is normal, HDD is a 

defective possibility size.

: The allophone does from HDD.

The set symptom  : “HDD Reading” doesn't end, or the 

HDD function doesn't operate nor-
mally.

Correspondence : It judges compared with normal goods, 

and if it is an obviously abnormal sound, 
HDD is a defective possibility size.

: “HDD Reading” doesn't end.

The set symptom  : Can CD reproduce?

Both the HDD and USB MICOM board are defective doubts.

The USB MICOM board is a defective doubt.

: HDD cannot reproduction/record-

ing/be forwarded.

: Did “HDD Reading” end?

Reconfi rm symptom 2.

: Can USB reproduce?

HDD is a defective possibility size.

Both the HDD and USB MICOM board are defective doubts.

: “Data Error” is displayed by a spe-

cifi c tune.

: Is it a tune where the copyright is 

protected?

It becomes this symptom if the tune where the copy-
right is protected is taken by way of USB, and it is 
not possible to reproduce (product specifi cation). 

: Is the extension of the 

fi

 le of the tune cor-

rect?

This display appears when the extension of the fi le is not 
corresponding to the content (product specifi cation).

: “Data Error” is always displayed.

: Does this symptom occur even if 

“COLD RESET” (Refer to page 13) 
is executed?

When this symptom occurs even if “Initializa-
tion Mode For Factory” (Refer to page 14) is 
executed, HDD is a defective possibility size.

Execute “HDD Writing/Reading Test” (Refer to page 14) 3 times when these symptoms do not reproduce it. It can be judged that HDD 
is normal if NG is not generated.
