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.
WARNING
Danger of explosion if battery is incorrectly replaced.
Replace only with the same of equivalent type.
Notes on the AC power adaptor
• Use only the supplied AC power adaptor. Do not use any other
AC power adaptor to avoid damaging the speaker.
Polarity of the plug
• Before connecting or disconnecting the AC power adaptor, turn
off the system. Otherwise, it may cause a malfunction.
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 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.
Refer to SUPPLEMENT-1 for the MAIN board of printed wiring
boards, schematic diagrams and electrical parts list of US and
Canadian models. When repairing the set of AEP and UK models,
refer to either of original service manual/SUPPLEMENT-1
according to the set.
