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.

Charge the headphones

The headphones contains a rechargeable LithiumIon battery. Charge the battery before use.

Connect the supplied AC power adaptor to the DC IN 6V jack on the headphones and an AC outlet. The charge indicator lights up in orange and charging starts.

Charging is completed after about three hours, and the charge indicator goes out. Disconnect the AC power adaptor after the charging has finished.

Charge indicator

Headphones

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 headphones and the battery case to “OFF.”

[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:

Pattern face side: (SIDE B) Parts face side: (SIDE A)

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

• Lead layouts

Parts on the pattern face side seen from the pattern face are indicated. Parts on the parts face side seen from the parts face are indicated.

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.
