CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
On power sources
• Use house current, nickel metal hydride
rechargeable battery, LR6 (size AA) battery,
or car battery.
• For use in your house: Do not use any other
AC power adaptor since it may cause the
recorder to malfunction
Polarity of the
plug
• Connect the AC power adaptor to an easily
accessible AC outlet. Should you notice an
abnormality in the AC power adaptor,
disconnect it from the AC outlet immediately.
• The recorder is not disconnected from the AC
power source (mains) as long as it is
connected to the wa ll outlet, even if the
recorder itself has been turned off.
• If you are not going to use this recorder for a
long time, be sure to disconnect the power
supply (AC power adaptor, dry battery,
rechargeable battery, or car battery cord). To
remove the AC power adaptor from the wall
outlet, grasp the adaptor plug itself; never pull
the cord.
.
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 the soldering iron around 270 ˚C dur-
ing 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 leadfree 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 flow) 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.

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 electrostatic 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 flexible 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.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
(LCX-5R)
The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering
bridge to the laser-tap on the flexible board. Also perform measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled
with care.
• In performing the repair with the power supplied to the set, removing the MAIN board causes the set to be disabled.
In such a case, fix a convex part of the open/close detect switch
(S803 on MAIN board) with a tape in advance.
Handle the FLEXIBLE board (over write head) with care, as it
has been soldered directly to the MAIN board.
In repairing the component side of MAIN board, connect the
FLEXIBLE board (over write head) and the MAIN board with
the lead wires in advance.

TEST MODE
MZ-N510CK
Outline
•This set provides the Overall adjustment mode that allows CD
and MO discs to be automatically adjusted when in the test mode.
In this overall adjustment mode, the disc is discriminated between CD and MO, and each adjustment is automatically executed in order. If a fault is found, the system displays its location. Also, the manual mode allo ws each indi vidual adjustment
to be automatically adjusted.
• Operation in the test mode is performed with the set. A key
having no particular description in the text, indicates a set key.
Setting Method of Test Mode
There are three different methods to set the test mode:
1 Short SL803 (TEST) on the MAIN board with a solder bridge
(connect pin <zx. of IC801 to the ground). Then, turn on the power .
– MAIN Board (Side B) –
Operation in Setting the Test Mode
• When the test mode becomes active, first the display check mode
is selected.
• Other mode can be selected from the display check mode.
•When the test mode is set, the LCD repeats the following display.

• When the X key is pressed and hold down, the display at that
time is held so that display can be checked.
Releasing the Test Mode
For test mode set with the method 1:
Turn off the power and open the solder bridge on SL803 (TEST)
on the MAIN board.
Note: Remove the solders completely. Remaining could be shorted with
the chassis, etc.
For test mode set with the method 2 or 3:
Turn off the power.
Note: If electrical adjustment (CD and MO overall adjustment) has not
been finished completely, “NV Error” is displayed on LCD of the

Self-Diagnosis Result Display Mode
This set uses the self-diagnostic function system in which if an
error occurred during the recording or playing, the mechanism
control block and the power supply control block in the
microcomputer detect it and record its cause as history in the
nonvolatile memory.
By checking this history in the test mode, you can analyze a fault
and determine its location.
Total recording time is recorded as a guideline of how long the
optical pick-up has been used, and by comparing it with the total
recording time at the time when an error occurred in the selfdiagnosis result display mode, you can determine when the error
occurred.
Clear both self-diagnosis history data and total recording time, if
the optical pick-up was replaced.
• Self-Diagnosis Result Display Mode Setting Method
