POWER indicator

After using the headphone system

Turn off the digital surround processor first before turning off the component connected to the digital surround processor. If you turn off the connected component first, the infrared beam is cut off and noise may be emitted (this is not a malfunction). Do not hang the headphones on the digital surround processor or other components. The Auto Power On Function may be inadvertently activated, using up the batteries.

Transition time between modes

When pressing buttons on the digital surround processor to change to new modes, the transition time between modes may vary. This is due to differences in program transmission between modes.

Mute Function

The Mute Function is automatically activated so that sound output from the headphones is cut off when the headphones are outside the infrared transmission area, or when the infrared beams are interrupted. The Mute Function is automatically cancelled when you get closer to the digital surround processor or there is no longer anything in the way of the infrared beams.

Operation

Infrared transmission area

The approximate infrared transmission area from the digital surround processor is shown in the illustration below.

Infrared beams

Approx.

Digital surround processor

Notes

• Because this system uses infrared beams, even if the headphones are within the transmission area shown above, electrical noise (hissing noises) may increase as the headphones get farther away from the digital surround processor. Also, if the infrared beams are blocked, the sound may be interrupted or noise may be heard. This is due to the infrared beam characteristics and is not a malfunction.

• Do not cover the infrared beam sensor with your hand or hair.

• As long as the headphones are in the transmission area shown in the illustration above, the

headphones can have any orientation with respect to the digital surround processor (facing, turned 90°, or turned 180°).

• The sound may differ depending on the digital surround processor position and conditions in the room. It is recommended that you place the digital surround processor in the location which produces the clearest sound.

• Mixed signals may result if the digital surround processor is used with other processors or transmitters.

How to attach the battery cover when it has come off

As shown in the illustration, align A with A, and B with B, and then attach the cover in place.

If an audio signal is not input for 10 minutes

Emission of the infrared beams from the digital surround processor automatically stops when an audio signal is not input for 10 minutes. The infrared beams are automatically emitted when an audio signal is input again. The emission of the infrared beams may stop when an extremely low sound is emitted for about 10 minutes during analog input. If this happens, raise the volume of the connected audio and video component and lower the volume of the headphones.

Notes

• There may be differences in brightness of the infrared transmitter on the digital surround processor. However, this does not affect the transmission area.

• The headphones should be used within the infrared transmission area (see “Infrared transmission area” on page 25).

• Do not use the digital surround processor in areas exposed to direct sunlight or strong light. The sound may be interrupted.

• These open-air headphones are designed so that the sound also flows outside the headphones. Be careful not to turn up the volume too high that it bothers the people around you.

• Use a suitable volume level so that you do not harm your hearing and to ensure that you can still hear surrounding sounds.

• The surround sound effect may not be obtained for sound sources which do not incorporate video, such as music CDs.

• This system simulates the HRTF* for an average person. However, the effect can differ from person to person since the HRTF can vary between individuals.
