( Operating the system

Listening to a program

1 Turn on the audio/video

equipment connected to the transmitter. When the audio signals 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.

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.

When no audio signal is received at the transmitter input for more than approximately five minutes

The transmitter will be turned off automatically.

3 Adjust the volume.

After listening to a program

Take the headphones off before the transmitter turns off. 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

Replacing the Ear

Approx. 3 m (1181/8 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 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.

•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.

Infrared ray

transmitter and the headphones.

/ Check that the infrared sensors are not

covered with your hands or hair.

/ The headphones’ power indicator light is

weak or turned off.

• Replace the battery of the headphones.

/ When the headphone’s jack output is

connected to the LINE IN jack of the transmitter, increasing the volume of the connected audio/video equipment may cause distortion. Connect the headphones jack output instead to PHONES IN jack as described in “Setting up the transmitter”.
