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.

Operation

Mute Function

The Mute Function is automatically activated so that sound output from the headphones is cut off whenever the headphones are outside the infrared transmission area, the infrared beams are interrupted, or the noise increases. 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.

If an audio signal is not input for 10 minutes

Emission of the infrared beams from the infrared transmitter in 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. In some cases, the infrared beams from the infrared transmitter 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 of the infrared beams.

• The headphones should be used within the infrared transmission area (see “Infrared

transmission area” on page 13).

• Do not use the digital surround processor in areas exposed to direct sunlight or strong light.

The sound may be cut off.

• These open-type headphones are designed so that the sound also flows outside the

headphones. Be careful not to turn up the volume so 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.
