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 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.
  IC400 (microcomputer) and IC450 (nor flash sram) on MAIN
    board cannot be replaced individually.
    Replace it with MAIN board assembly for service.
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.
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.

time will be “-- --.”
• If PC CLK is set to “ON”, the time setting of your
Network Walkman is automatically adjusted to a 
computer’s built-in clock when your Network Walkman
is connected to the computer.
• Depending on the shipping area, the time display
format of the unit is set to a 12-hour display or a 24-
hour display.
You cannot switch between a 12-hour display and a 24-
hour display in the unit.
A 24-hour display is shown in this manual.
