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.

Power Sources
Using on house current
(See fig.
A)
When the AC power adaptor is connected to the system,
internal batteries are automatically disconnected.
Setting the stand
(See fig.
C)
Retract into the stand when carrying the speaker.
Installing/Removing the
attachment
(See fig.
D)
Installing the attachment according to the Walkman
you are using
Use the dedicated attachment for either NW-A1000 or
NW-A3000 series. The corresponding model number is
marked on the rear of the attachment. Exchange attachments,
as shown.
Hooking up the speaker
(See fig.
E)
Connect the speaker to the source equipment.
When the system is connected to the monaural jack
of a radio, etc., the sound may not come through the right
speaker. In such a case, use the optional* plug adaptor PC-
234S or PC-236MS.
To connect to a stereo phone-type
headphones jack
Use the optional* plug adaptor PC-234S/PC236MS or
connecting cord RK-G136/RK-G138.
* The above optional accessories are not provided in some areas.
Notes
·NW-A1000/A3000 series use the multiple connector (Walkman
connection).
· Do not carry the speaker with a Walkman set on the multiple
connector, as malfunction may result.
Playing back sound of the
connected device
(See fig.
F)
Adjust VOLUME to minimum to avoid any sudden loud
sounds that may hurt your ears and set the volume of the
connected device to a moderate level.
1
Disconnect the USB cable used for the
speaker and personal computer, or set
the POWER switch of the connected
personal computer to OFF.
· When a USB cable is connected between the speaker
and a personal computer, no sound will be heard from
a Walkman set on the multiple connector, as data
transfer mode takes place. Sound from the device
connected to INPUT will be heard instead.
2
Set the POWER switch to ON.
The POWER/CHARGE indicator lights up.
3
Play back the connected device.
Adjust VOLUME accordingly.
· When both a Walkman set on the multiple connector
and a device connected to INPUT are used, both
sounds can be heard. Control on/off on the connected
device itself.
4
Set the POWER switch to OFF after
using.
The POWER/CHARGE indicator goes off.
Notes
· If connecting the speaker to a device with built-in a radio or
tuner, radio reception may not occur or sensitivity may be
reduced significantly.
· Release the bass boost function of the connected Walkman, etc.,
to avoid distortion.
· The USB cable connecting the speaker with personal computer
is used for transferring Walkman's data and recharging. When
playing back sound of a personal computer using the speaker,
connect through the INPUT.
· If the connected device's headphone output has a line switch,
better sound will be heard if it is set to on. See the operating
instructions of the connected device.
Battery installation (See fig. B)
Battery replacement
When the batteries are weak, the POWER/CHARGE
indicator will start flickering and become faint, or the
playback sound will become distorted or unstable. In such a
case, replace all the batteries with new ones.
