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 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.
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.
Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
This appliance is classified as
a CLASS 1 LASER product.
This marking is located on the
rear exterior.
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radia-
tion exposure.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostat-
ic 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
pickup block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.

SERVICING NOTES
Notes on Disconnecting Between the OP Section (DVBU101) and the DMB18 Board
Note: When disconnecting between the OP section (DVBU101) and the DMB18 board, be sure to make a solder brige for electrostatic
prevention as illustrated in the figure (before disconnection).
On the contrary, when installing the OP section, never remove the solder bride until the OP section and the DMB18 board are
connected.
Be sure to remove the solder bridge after the OP section and the DMB18 board have been connected.
Service Position for the DVD Mechanism Deck Section
Refer to the figure given below when disassembling the DVD mechanism deck section.
Perform solder bridging to prevent damage by electrostatic
discharge when handling the BU as a single unit.

Note: The HCD-GZR8D/GZR9D has two cooling fans (FAN901 and FAN902) used. The connectors of these fans have the same color
and the same number of pins.
When installing these fans, check the marking of CN601 and CN602 on the MAIN board and ensure that they are located correctly.
The CN601 on the MAIN board is to be attached with the connector of FAN901 where as the CN602 is to be attached with the
connector of FAN902.
