Use of controls or adjustments or performance of procedures

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 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.
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 ËšC 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 ËšC .
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.
On power sources
-Use house current, Nickel Cadmium
rechargeable battery, LR6 (size AA) battery,
or car 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.
