* When listening through the speaker. Measured by JEITA (Japan Electronics and Information Technology
Industries Association) standards. The actual battery life may va ry depending on usage and circumstances.
Design and specifications are subject to change without notice.
Operate the unit only on the power sources specified in “Specific ations. ” For battery oper ation,
use four LR6 (size AA) alkaline batteries. For AC operation, use only the supplied AC adaptor.
Do not use any other type of AC adaptor.
Failure to use the supplied AC adaptor may cause the unit to malfunction, as
the polarity of the plugs of other manufacturers may be different.
When operating the unit on batteries, it is recommended that you remove the AC adaptor from
the wall outlet and the DC IN 6 V jack. Disconnect the plug of the external power source before
operating the unit.

SECTION 1
SERVICING NOTES
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.
