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
person to person since the HRTF can vary between individuals.
