UNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the leadfree 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 viscou-s (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.

NOTE THE IC301, IC302, IC501, IC503, IC505, IC506, IC509, IC601, IC602, IC701, IC802, IC803, IC901 AND IC903 ON THE MAIN BOARD REPLACING

When IC301, IC302, IC501, IC503, IC505, IC506, IC509, IC601, IC602, IC701, IC802, IC803, IC901 and IC903 on the MAIN board is damaged, exchange the new MAIN board for the MAIN board which IC damaged.

Notes on chip component replacement

• Never reuse a disconnected chip component.

• Notice that the minus side of a tantalum capacitor may be

damaged by heat.

Flexible Circuit Board Repairing

• Keep the temperature of the soldering iron around 270 ˚C

during 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.

CAUTION

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.

NOTE THE CN601 ON THE MAIN BOARD REPLACING

When CN601 on the MAIN board is damaged, exchange the new MAIN board for the MAIN board which connector damaged.

NW-A805/A806/A808

NOTE THE MAIN BOARD REPLACING

When the MAIN board is replaced, format it according to the following.

Formatting Memory

You can format the built-in flash memory of the player. If the memory is formatted, all music, video and photo data, etc., will be erased.
