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.
Flexible Circuit Board Repairing
-K
eep the temperature of the soldering iron around 270 ËšC 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.
Notes on chip component replacement
-N ever reuse a disconnected chip component.
- Notice that the minus side of a tantalum capacitor may be dam-
aged by heat. CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous
radiation exposure.
CAUTION
- INVISIBLE LASER RADIATION
WHEN OPEN
- DO NOT STARE INTO BEAM OR
VIEW DIRECTLY WITH OPTICAL
INSTRUMENTS
- CLASS 1M INVISIBLE LASER
RADIATION WHEN OPEN
- DO NOT VIEW DIRECTLY WITH
OPTICAL INSTRUMENTS
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.
