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.

FLEXIBLE  CIRCUIT  BOARD  REPAIRING
• 

Keep the temperature of soldering iron around 270 °C during 
repairing.

• 

Do not touch the soldering iron on the same conductor of the 
circuit board (within 3 times).

• 

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 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
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:
1.  Press the [

?/1

] button to turn the power on.

2.  Press two buttons of [

x

] and [

Z

] for 5 seconds.

3.  The message “UNLOCKED” is displayed on the fl uorescent 

indicator tube and the disc tray is unlocked.

Note: When “LOCKED”is displayed, the disc tray lock is not released by 

turning power on/off with the [

?/1] button.

NOTE  OF  REPLACING  THE  MOTOR  BOARD
When the MOTOR board is damaged, exchange the entire 
LOADING (BK) ASSY.

NOTE  OF  REPLACING  THE  IC107,  Q1101,  Q1102,  
Q2101  AND  Q2102  ON  THE  AMP  BOARD
IC107, Q1101, Q1102, Q2101 and Q2102 on the AMP board can-
not exchange with single. When these parts are damaged, exchange 
the entire mounted board.

PRECAUTIONS  FOR  DISASSEMBLY  AND  ASSEMBLY
Many of the internal parts in this unit use iron plates. Be careful not 
to injure your hands while carrying out disassembly or assembly 
procedures. 

PRECAUTIONS  FOR  OPERATION  CHECKS
If checking operations with the power on, be sure to connect the 
GND wires (earth terminals) connected to the AMP board and 
MAIN board to ground. 
The units may fail to operate and parts may become damaged if 
the GND wires are not connected properly. Be sure to connect the 
GND wires before checking either board. 
If the GND wire (earth terminal) is not long enough to reach when 
the circuit board is removed, use alligator clips or a similar part to 
extend the length to enable connection to ground. 

Note: Connect the alligator clips surely with this position.
