CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.
On power sources
• Use house current, LR6 (size AA) battery.
•
For use in your house: use the AC power adaptor
supplied with this recorder. Do not use any other
AC power adaptor since it may cause the recorder
to malfunction.
Polarity of the
plug
• 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.
• The recorder is not disconnected from the AC
power source (mains) as long as it is
connected to the wall outlet, even if the
recorder itself has been turned off.
• If you are not going to use this recorder for a
long time, be sure to disconnect the power
supply (AC power adaptor, dry battery). To
remove the AC power adaptor from the wall
outlet, grasp the adaptor plug itself; never pull
the cord.
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 the soldering iron around 270 ˚C 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.
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.
