N Operating the system

Listening to a programme
Before listening To prevent your ears from being damaged, first lower the volume.

Adjust the volume.

Turn on the audio/video component connected to the transmitter.
When the audio signal is input, the transmitter turns on automatically and the infrared emitters glow but they do not glow while the transmitter is charging the batteries. If the transmitter is connected to the headphone jack, set the volume control of the audio source component as high as possible but not so high that the audio signal becomes distorted.
Notes You may hear some noise when you disconnect the AC power adaptor from the transmitter before taking off the headphones. If the infrared sensors are covered by your hands when adjusting the volume, the mute function will be activated and volume may not be adjusted. To adjust the volume, move nearer toward the transmitter or orient the infrared emitters on the left housing towards the transmitter.

Put on the headphones.

The power indicator on the upper part of the right housing glows red. Be sure to put the right housing (R) on your right ear and the left housing (L) on your left ear. Wear the headphones vertically on your head so that auto power on function is properly activated.
Start playback of the component connected to the transmitter.
The headphones automatically turn off when they are taken off Auto power on/off function Do not pull up the self-adjusting band when not in use, as this will consume the battery power.
Using SRS surround function switch to ON to reproduce Set the a wide surround sound field through the headphones.
Using the ATT (Attenuator) switch Sound is automatically muted if noise increases Mute function If the infrared rays are obstructed, or the headphones are used outside their effective range, noise will increase and sound will become hard to hear. To avoid potential ear damage as a result of noise, this function mute any sound from the headphones. Sound is automatically restored when you move nearer the transmitter or remove the obstruction. Using the vibration function Set the VIBRATION switch to ON and adjust the level of vibration using the vibration volume. You can enjoy powerful bass sound when you listen to movies or games through the headphones. If the input volume is low, set the ATT switch on the transmitter to OFF.

If no audio signal is input for more than approximately 5 minutes The transmitter turns off automatically.
Note The brightness of the infrared emitters may not be uniform, however, this is not a malfunction.
The effective area of the transmitter
The illustration below shows the approximate area covered by the infrared rays emitted from the transmitter.
Transmitter Infrared ray Approx. 3 m (118 1/8 in.)

Replacing the ear pads

The ear pads are replaceable. If the ear pads become dirty or worn out, replace them as illustrated below. The ear pad is not commercially available. You can order replacements from the store where you purchased this system, or at your nearest Sony dealer.

Approx. 7 m (23 ft.)

Remove the old ear pad by pulling it off.
Approx. 3 m (118 1/8 in.)
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 headphones and the transmitter, sound may be interrupted. These phenomena are inherent to infrared ray communication and do not mean that there is a problem with the system itself. Do not cover the infrared sensors with your hands or hair. When you use the headphones inside the area in the illustration above, the transmitter can be placed in front, behind or by the side of you. The noise you may hear through the headphones may vary depending on the transmitter position and room conditions. It is recommended that you place the transmitter in a location that produces the clearest sound. Do not use this system in areas exposed to direct sunlight or strong light. The sound may be interrupted. Plasma displays may interfere with normal operation of this system.
Place the new ear pad around the housing.
