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.
