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.

COMPONENTS  IDENTIFIED  BY  MARK  0  OR  DOTTED  LINE  
WITH  MARK  0  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN

CAUTION
Use of controls or adjustments or performance of procedures 
other than those specifi ed herein may result in hazardous radia-
tion exposure.

This appliance is classified as a CLASS 1 
LASER product. This marking is located on 
the rear exterior.

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.

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  OF  REPLACING  THE  IC102  ON  THE  DMB19C-
32NUA  BOARD
IC102 on the DMB19C-32NUA board cannot exchange with 
single. When this part is damaged, exchange the entire mounted 
board.

NOTE  OF  REPLACING  THE  MS-214  BOARD
When the MS-214 board is damaged, exchange the entire MD 
(AU) ASSY.

NOTE  OF  REPLACING  THE  TOUCH  PANEL  BOARD
When the TOUCH PANEL board is damaged, exchange the entire 
PANEL (DISPLAY TOP) ASSY.

Z100iR: AEP model

AC: 220-240V - 50/60Hz 30W

CMT-Z100iR: 
E2 model

AC: 110-120/220-240V - 50/60Hz 30W

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  SLOT  LOCK
The disc slot lock function for the antitheft of an demonstration 
disc in the store is equipped.

Releasing Procedure:
1. Press 

[

?/1

] button to turn the power on.

2.  Touch the [FUNCTION +] sensor to select CD function.
3. While 

touching 

the 

[

x

] sensor, press the [

Z

] button for more 5 

seconds.

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

unlocked.

Note: When 

“

LOCKED

”

 is displayed, the slot lock is not released by 

turning power on/off with the

 [

?/1

]

 button.
