Accessories are given in the last of the electrical parts list.

The laser diode in the optical pick-up block may suffer electro-
static 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.

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.

NOTE  THE  MAIN  BOARD  OR  SYSTEM  CONTROLLER 
(IC501) REPLACING
When the MAIN board or system controller (IC501) is replaced, 
the destination setting is necessary. 

Set destination according to the procedure below.

1-1.  Setting the Destination Code
1.  In the state of source off (the clock is displayed), enter the test 

mode by pressing the buttons in order of the [4] 

t [5] t [6] 

(press only the [6] button for two seconds).

2.  In the state in which the system controller version is displayed 

on the liquid crystal display, enter the destination setting mode 
by pressing the buttons in order of the [SEEK +] 

t [SEEK –] 

t [PUSH ENTER/SELECT].

3.  Input the alphanumeric character of 6 digits of “F    XXXXXX” 

displayed on the liquid crystal display, and execute the destina-
tion setting.

Note: Refer to following “1-3. Entering the Destination Code” for opera-

tion method.

4.  The resetting operation is executed by pressing the [SOURCE/

OFF] button for 1 second after the setting ends, and the unit 
returns to the normal condition.

1.  Rotate the control dial, and select the alphanumeric character 

of “0 to F”.

2.  The digit advances by pressing the [PUSH ENTER] or [SEEK 

+] button.

 

The digit returns by pressing the [ ] or [SEEK –] button.

3.  The setting is completed by pressing the [PUSH ENTER] but-

ton, and the initialization operation is done.

1. Press 

the 

[ ] or [ ] button, and select the alphanumeric char-

acter of “0 to F”.

2.  The digit advances by pressing the [

] button.

 

The digit returns by pressing the [

] button.

3.  The setting is completed by pressing the [ENTER] button, and 

the initialization operation is done.

2. Confi rmation After Destination Setting
Execute the following operation after completing the destination 
setting, and confi rm a correct destination was set.

Destination setting checking method:
1.  In the state of source off (the clock is displayed on the liquid 

crystal display),  enter the test mode by pressing the buttons in 
order of the [4] 

t [5] t [6] (press only the [6] button for two 

seconds).

2.  In the state in which the system controller version is displayed 

on the liquid crystal display, enter the destination setting value 
display mode by pressing the [DISP] button.

3. Confi 

rm the alphanumeric character of 6 digits of “F 

 

 

 

XXXXXX” displayed in liquid crystal display is an value cor-
rectly input.

4.  The resetting operation is executed by pressing the [SOURCE/

OFF] button for 1 second after the confi rming ends, and the 
unit returns to the normal condition.

NOTE  FOR  REPLACEMENT  OF  THE  USB  CONNEC-
TOR (CN971)  AND  THE  AUX  JACK (J901)
To replace the USB connector and the AUX jack requires align-
ment.
1.  Insert the USB connector and the AUX jack into the front pan-

el.

2.  Place the KEY board on the front panel and align the terminals 

of the USB connector and the AUX jack with the holes in the 
KEY board.

3.  Solder six terminals of the connector and three terminals of the 

jack.
