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.
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.

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 the power source
Disconnect all power sources when the CD player is not used for a
long time.
On AC power adaptor
• Use only the AC power adaptor supplied.
If your CD player is not supplied with the one, use the AC-E30HG
AC power adaptor. Do not use any other AC power adaptor. It
may cause a malfunction.
Polarity of the plug
• Do not touch the AC power adaptor with wet hands.
• 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.
