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 curre nt, nikel metal hyd ride rechargeable battery, LR6 (S G) battery, or car

battery.

For use in your house: For the s uppl ied battery charging s ta nd, use the AC power adaptor

s uppl ied with this recorder. Do not use an y other AC power adaptor s ince it ma y cause the recorder to malfuncti on.

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.
