NW-HD3

Notes on the AC power adaptor

• Use only the AC power adaptor and the USB adaptor supplied with the player. Do not use any other AC power adaptor since this may cause the player to malfunction.

• The player is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the player itself has been turned off.

• If you are not going to use the player for a long time, be sure to disconnect the power supply. 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

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.

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 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.

• Replacement of CXR704060-201GA (IC1003),

S1R72003BOOA100 (IC2001), CXR710160-211GH (IC3001), CXD1616GH (IC7001), EDL1216CASA-10L-E (IC7002) and SC901584EPR2 (IC9002) used in this set requires a special tool.

• When IC1101 and IC1102 (IC1102 is mounted only E, Hong

Kong, Taiwan, Korean, Chinese and Tourist models) are damaged, exchange the new MAIN board for the MAIN board which IC damaged.
