SERVICING NOTES
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 fl ow)
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.

When the rechargeable
battery is low
When the rechargeable battery is low, short beeps
sound from the unit for 8 seconds and the
POWER indicator blinks slowly.
When the battery level is getting lower, a long
beep sounds from the unit for 2 seconds and the
POWER indicator blinks quickly, and all
operations are stopped. Move the POWER switch
to “OFF” in this case.
[Tips
When the battery runs out, you can supply the power to
the headphones in one of the following ways:
• Connect the headphones to the AC power adaptor by
following the steps shown in “Charge the
headphones.”
You can use the headphones while charging.
• Use the supplied connecting cord with battery case.
See “How to use the connecting cord with battery
case” for details.
Using your AC power
adaptor abroad
You can use yourAC power adaptor in any
country or area that uses 100 V to 240 VAC,
50/60 Hz, by connecting a plug adaptor. If the
country you visit employs a different shaped
socket, use the correct plug adaptor.
Consult your nearest travel bureau for the type of
plug adaptor needed for your trip.
Listening to music
1 Connect the headphones to the AV
equipment.
When connecting
to the stereo mini
jack of a
WALKMAN*, etc.
When connecting
to the stereo mini
jack of the remote
control supplied
with a WALKMAN,
etc.
* “WALKMAN” and “WALKMAN” logo are
registered trademarks of Sony Corporation.
Notes
• When connecting the cord, insert the plug into the
jack until the green portion of the plug disappears.
• To disconnect the cord, pull it out by the plug, not
the cord, as the inner conductors may break.
2 Turn on the power on the right side of the
headphones.
The POWER indicator lights up in blue, and a
short beep sounds from the unit.
3 Put on the headphones.
After confirming the cord on the left and the
POWER switch on the right, put on the
headphones.
Adjust the ear pads so as to cover your ears.
4 Start playing on the AV equipment
connected to the headphones.
Note
Playback is not available when there is no
power.

Utilizing the AI Noise
Canceling
1 Press the AI NC MODE button.
When you press the AI NC MODE
the POWER switch is set to “ON”, sounds
come from the headphones to inform you that
the unit has started analyzing ambient sound
components (approx. 3 seconds).
During analysis, sound reproduction from the
unit is stopped and the POWER indicator
lights in pink.
When analysis is completed, the most
effective noise canceling mode is set
automatically, and sound reproduction from
the headphones starts.
AI Noise Canceling
AI Noise Canceling is a useful function that
automatically selects one of the noise canceling
modes. This function provides the most effective
noise canceling mode by immediately analyzing
ambient sound components when the AI NC
MODE button is pressed.
[Tips
• When the power of the headphones is turned on,
mode A is set. (See “Noise canceling mode types,”
for details about Mode A.)
• Press the AI NC MODE button again to reset the
noise canceling mode if ambient noise has changed,
such as when you move outdoors from a room.
To set the noise canceling mode
manually
You can set the noise canceling mode manually
(manual noise canceling).
1 Press and hold the AI NC MODE button
for more than one second.
Sounds ( ) come from the headphones to
inform you that manual noise canceling is set.
2 Press the AI NC MODE button
repeatedly to change the mode type.
The POWER indicator blinks pink and a
beep(s) sound(s) from the headphones. After
that, the noise canceling mode is set. The
number of POWER indicator blinks and the
beep sounds depends on the mode selected.
See “Noise canceling mode types.”
[Tips
• Mode A is selected when manual noise canceling is
activated.
• To change from manual noise canceling to AI Noise
Canceling, press and hold the AI NC MODE button
for more than one second. When you hear the sounds

How to use the
connecting cord with
the battery case
You can continue to use the unit, even when the
rechargeable battery in the headphones runs out,
by connecting the supplied connecting cord with
battery case.
Use the connecting cord with battery case by
inserting two size AA alkaline batteries.
1 Open the lid of the battery case.
2 Insert two size AA alkaline batteries.
Make sure of direction, matching the F
marks in the case with those on the batteries.
3 Close the lid.
4 Connect the supplied connecting cord
with the battery case to both the
headphones and AV equipment.

See steps 2 to 4 of “Listening to music” for
the following setting steps.
After use, set the POWER switch of both the

[Tips
• The power supply of the rechargeable battery is
consumed first, unless the battery runs out.
• If you connect and turn on the connecting cord with
the battery case in advance when the rechargeable
battery is low, you can use the headphones
uninterrupted, even after the battery in the
headphones runs out.
Notes
• The use of manganese batteries is not recommended,
since this type of battery has an extremely short
usage time.
• The battery case supplies the power to the
headphones for operation purposes only. It does not
charge the internal rechargeable battery in the
headphones.
• The POWER indicator of the battery case becomes
dim when the battery life is reaching the limit.
Replace the battery with new ones at the time.
• The supplied connecting cord with battery case is
only for these headphones. Do not connect to other
equipment.
After use
Turn off the power of the headphones.
Flat Storage
he housings rotate to make them flat for easy
storage in the carrying case (supplied), or in a seat
pocket. Restore to their usual position before using.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
• Y : parts extracted from the conductor side.
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:

• MAIN board is multi-layer printed board. However, the
patterns of intermediate-layers have not been included in
diagrams.
• Lead layouts

CSP (Chip Size Package) Lead layout of conventional IC
For Schematic Diagrams.
Note:
• All capacitors are in µF unless otherwise noted. (p: pF) 50
WV or less are not indicated except for electrolytics and
tantalums.
• All resistors are in Ω and 1/4 W or less unless otherwise
specifi ed.
• A : B+ Line.
• H : adjustment for repair.
• Power voltage is dc 3.7 V and fed with regulated dc power
supply from CN403 pin 1 and pin 2 on the CHARGER
board.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : POWER ON
• Voltages are taken with VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal production
tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal production
tolerances.
• Circled numbers refer to waveforms.
• Signal path.
F : AUDIO (ANALOG)
J : AUDIO (DIGITAL)
N : MONITOR
• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
from that of conventional IC.
Note: IC402 on the CHARGER board cannot exchange with single. When this part on the
CHARGER board is damaged, exchange the entire mounted board.
