On/off switch

Notes

- Do not connect to the AUDIO IN A and B jacks at the same time. If you do so, the audio signals may be mixed. - Use only the supplied AC power adaptor. Do not use any other AC power adaptor.

Polarity of the plug

• Keep the AC power adaptor cord as far away from the transmitter as possible. If the cord is positioned near the transmitter, noise may occur.
• When you connect the transmitter directly to a monaural earphone jack, the audio signal will not be output through the right channel. In such a case, use the separately sold PC-236HG plug adaptor.
• If the connected equipment has the AVLS (Automatic Volume Limiter System) function, be sure to turn the function off when using the transmitter. Otherwise, you will have to turn up the volume of the headphones, and that may cause noise.

Charging the headphone batteries

Using the headphones for the first time

When you use the headphones for the first time, charge the batteries in the following manner.

1 Connect the transmitter to a power source.

Transmitter B R A L DC IN 9V AUDIO IN to DC IN 9 V jack to an AC outlet AC power adaptor (supplied)

2 Place the headphones on the transmitter so that the charging pins on the transmitter engage the charging contacts on the bottom of the headphones.

The CHG (charge) indicator on the transmitter will light in green to indicate that the batteries are being charged.

CHG

The charge indicator goes off after about 14 hours when the charging is completed.

When the charge indicator is not lit

Check the connection to make sure that the contact pins are properly fitted into the contact holes on the headphones, or if the headphones are rested on the transmitter correctly.

To recharge the headphone batteries after use

This system automatically stops charging by the built-in timer to prevent the risk of damage to the headphones due to overcharging. For this reason, we recommend that you rest the headphones on the transmitter whenever you do not use the headphones.

Charging and using hours

Approx. charging hours	Approx. using time*

If a loud sound is distorted when the transmitter is connected to an audio output jack other than the headphones jack, set the ATT selector on the transmitter to -12 dB. The default setting of the ATT selector is 0 dB.

ATT selector ATT -12dB0dB

Auto power on/off function

When you remove the headphones, the power turns off automatically. Do not allow the suspender to be pulled up, otherwise the headphones will be switched on.

Suspender

Mute function

If a hissing noise is heard when the infrared rays are obstructed, or the headphones are used outside of the effective range (see right column), the mute function will be activated and the sound will not be heard from the headphones. To restore the sound, move nearer toward the transmitter or remove the obstruction.

When no audio signal is received for more than approximately five minutes

The transmitter will be turned off automatically.

When an audio signal is intermittent or a low-level audio signal continues for more than approximately five minutes

The transmitter may be turned off automatically. In this case, turn up the volume of the connected equipment while turning down the volume of the headphones.

After listening to a program

Take the headphones off and rest them on the transmitter. Then turn off the connected audio/video equipment. The transmitter power will be turned off automatically if no audio signal is input from the audio/video equipment for more than approximately five minutes.

Note

The infrared emitters light up when the transmitter is turned on. The brightness of the emitters may not be uniform, however, this is not a malfunction.

The effective areas of the transmitter

The illustration below shows the approximate area covered by the infrared rays emitted from the transmitter.

Approx. 4 m (157½ in.) Infrared ray Transmitter 45° 45° Approx. 10 m (32.8 ft.) Approx. 4 m (157½ in.)

Notes

• This system utilizes infrared rays for communication so noise (hissing) can be heard from the headphones as you move farther away from the transmitter. The sound will also be cutoff and noise will be heard if the infrared rays are blocked. These are characteristics of infrared ray communication and do not indicate malfunction.
• The infrared rays will not penetrate walls or opaque glass, therefore, be sure to stay within sight of the transmitter.
• When you use the headphones inside the area illustrated in the diagram, the transmitter can be placed in the front, behind or by the side of the listener.
• The sound you hear varies according to your position and the transmitter position. Try finding a position which yields the best sound.
• Do not cover the infrared sensors with your hands or hair.

Additional information

Precautions

• The CE mark on the unit is valid only for products marketed in the European Union.
• When the transmitter is not to be used for a long period of time, disconnect the AC power adaptor from the AC outlet holding the plug. Do not pull on the cord. If your AC power adaptor is equipped with an on/off switch, set it to off.
• Do not leave the cordless stereo headphone system in a location subject to direct sunlight, heat or moisture.

Notes on headphones

Preventing hearing damage

Avoid using headphones at high volume.

Hearing experts advise against continuous, loud and extended play. If you experience a ringing in your ears, reduce the volume or discontinue use.

Caring for others

Keep the volume at a moderate level. This will allow you to hear outside sounds and to be considerate to the people around you.

If you have any questions or problems concerning the system that are not covered in this manual, please consult the nearest Sony dealer.

Be sure to bring the headphones and the transmitter to the Sony dealer when requiring repair work.

Replacing the ear pads

When the ear pads become dirty or damaged, you can get replacements from your Sony dealer.

Disposing of the headphones

For environmental conservation, be sure to remove the built-in rechargeable batteries from the headphones before you dispose of the headphones, and dispose of the batteries appropriately.

1 Remove the left headphone's ear pad. Then remove the four screws from the housing and open the housing.
