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.

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 PC234S 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.

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.

Set the POWER switch to ON.

The POWER/CHARGE indicator lights up.

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.

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.
