Check the remaining power of the headphones’ battery
Pull up the self adjusting band, and check that the headphones’ power indicator lights in red. You can now use the headphones. Charge the battery or install a new dry battery, if the power indicator light is weak or turned off and the sound becomes distorted or has a lot of noise.
Notes
•During recharging, the transmitter is turned off automatically.
•When the life of the rechargeable battery is shortened by half even after a proper recharging, take the headphone set to a Sony dealer and have the old rechargeable battery replaced by a new one.
Removing the battery
1Open the battery compartment lid.
2Remove the battery from the battery compartment.

( Operating the system
Listening to a program
1 Turn on the audio/video equipment connected to the transmitter.
When the audio signal is input, the transmitter turns on automatically and the infrared emitters glow. If the transmitter is connected to the headphone jack, set the volume control of the audio source equipment as high as possible but not so high that the audio signal gets distorted. (Around level 5 or 6 on the volume control should be appropriate.)
2 Put on the headphones and the power turns on automatically.
The power indicator glows red when the power turns on.
3 Adjust the volume.
8
Auto power on/off function
When you remove the headphones, the power turns off automatically. Do not pull up the self adjusting band when not using the headphones, otherwise the headphones will be switched on.
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 the next section), 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.
If no audio signal is received at the transmitter for more than approximately five minutes, the transmitter turns off automatically.
After listening to a program, take the headphones off before the transmitter turns off and rest them on the transmitter.
Otherwise you may hear some noise when the infrared rays are suddenly cut off.
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.

Notes
•If you use the headphones at too great a distance from the transmitter, you may hear a hissing noise and if there is an object between the receiver and the transmitter, the sound may be interrupted. These phenomena are inherent to infrared ray communication and do not mean that there is a problem with the unit itself.
•Do not cover the infrared sensors with your hands or hair.
•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 diagrams, the transmitter can be placed in the front, behind or by the side of the listener.

Replacing the ear pads
When the ear pads become dirty or damaged, you can get replacements from your Sony dealer. Replace them as illustrated below.
1 Remove the old ear pad by pulling it off from the driver unit.
2 Place the new ear pad around the driver unit as illustrated.
( 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.
•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.

Troubleshooting
No sound/Muffled sound
/Turn on the transmitter first, then put on the headphones.
/Check the connection of the audio/video equipment or the AC power adaptor.
/Check that the input select switch position is correct.
/Check that the audio/video equipment is turned on.
/Turn up the volume on the connected audio/video equipment, if the transmitter is connected to the headphones jack. (Around level 5 or 6 on the volume control should be appropriate.)
/The mute function is activated.
•Check if there is any object between the transmitter and the headphones.
•Use the headphones near the transmitter.
•Change the position and angle of the transmitter.
/The headphones’ power indicator light is weak or turned off.
•Charge the rechargeable battery because the headphones’ battery is weak, or if the power indicator is still off after charging the battery. Take the headphones to a Sony dealer for a replacement of the rechargeable battery.
•If you are using the conventional dry battery, replace it with a new one.
/When the LINE OUT jack of your audio/ video equipment is connected to PHONES IN (A) of the transmitter, the sound will be low. Connect the LINE OUT jack to the LINE IN (B) as described in “Setting up the transmitter.”
Distortion
/If the transmitter is connected to the headphones jack, turn down the volume of the connected audio/video equipment. (Around level 5 or 6 on the volume control should be appropriate.)
/The headphones’ power indicator light is weak or turned off.
•Charge the rechargeable battery because the headphones’ battery is weak, or if the power indicator is still off after charging the battery. Take the headphones to a Sony dealer for a replacement of the rechargeable battery.
•If you are using the conventional dry battery, replace it with a new one.
/When the headphones jack output is connected to the LINE IN (B) of the transmitter, increasing the volume of the connected audio/video equipment may cause distortion. Connect the headphones jack output instead to PHONES IN (A) as described in “Setting up the transmitter.”
Loud background noise
/Move closer to the transmitter. As you move away from the transmitter, more noise is likely to be heard. This is inherent to infrared ray communication and does not mean that there is a problem with the unit itself.
/Check that there is no object between the transmitter and the headphones.
/Check that the infrared sensors are not covered with your hands or hair.
/Change the position or angle of the transmitter.
•The headphones are used by a window where the sunlight is too strong.
n Draw the curtains/blind to shut out the direct sunlight, or use the headphones away from the sunlight.
/If the transmitter is connected to the headphones jack, turn up the volume of the connected audio/video equipment. (Around level 5 or 6 on the volume control should be appropriate.)
/The headphones’ power indicator light is weak or turned off.
•Charge the rechargeable battery because the headphones’ battery is weak, or if the power indicator is still off after charging the battery. Take the headphones to a Sony dealer for a replacement of the rechargeable battery.
•If you are using the conventional dry battery, replace it with a new one.
