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)
: 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 viscou-s (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.
Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the 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.
This appliance is classified as
a CLASS 1 LASER product.
This marking is located on the
rear of the unit.

HCD-DZ20 SECTION 1
SERVICING NOTE
NOTES ON HANDLINGTHE 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
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH
1. Open the case and turn POWER on with no disc inserted.
2. Confirm that the following operation is performed while
observing the objecting lens from the clearance of DVD
mechanism deck.
1) Confirm that laser beam is spread.
2) Up and down motion of the objective lens. (2 times)
On cleaning discs, disc/lens cleaners
•Do not use cleaning discs or disc/lens cleaners
(including wet or spray types). These may cause the apparatus
to malfunction.
IMPORTANT NOTICE
Caution: This system is capable of holding a still video image or
on-screen display image on your television screen indefinitely.

still left on it
Notes about CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/
DVD+RW
In some cases, CD-R/CD-RW/DVD-R/DVD-RW/DVD+R/
DVD+RW cannot be played on this system due to the recording
quality or physical condition of the disc, or the characteristics of
the recording device and authoring software.
The disc will not play if it has not been correctly finalized. For
more information, see the operating instructions for the recording
device.

Precaution when installing a new OP unit /
Precaution before unsoldering the static electricity prevention solder bridge
When installing a new OP unit, be sure to connect the flexible printed circuit board first of all
before removing the static electricity prevention solder bridge by unsoldering.
Remove the static electricity prevention solder bridge by unsoldering after the flexible printed
circuit board has already been connected.
(Do not remove nor unsolder the solder bridge as long as the OP unit is kept standalone.)
