CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra-
diation exposure.

• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

• 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.

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)

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.

•

Use house current, nickel metal hydride 
rechargeable battery, LR6 (size AA) battery, 
or car battery.

•

For use in your house: For the supplied battery 
charging stand, 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.

•

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, 
rechargeable battery, or car battery cord). To 
remove the AC power adaptor from the wall 
outlet, grasp the adaptor plug itself; never pull 
the cord.
