Use the headphones near the digital surround processor. The amount of noise
increases as the headphones become farther from the digital surround
processor. This is due to the characteristics of the infrared beams and is not a
malfunction.
/
Check that there is nothing blocking the path from the digital surround
processor to the headphones.
/ Check that your hand or hair is not covering the infrared sensor on the
headphones.
/ If direct sunlight is entering the room from a window near the digital
surround processor or headphones, close the curtain or blinds so that no direct
sunlight is let in. Or, use in a location not exposed to direct sunlight.
/ Change the position or angle of the digital surround processor.
/ Set the ATT (attenuator) switch on the digital surround processor to “0dB”.
/ The POWER indicator on the headphones is faint or out. This indicates that
the battery power is low. If you are using rechargeable batteries, recharge the
batteries. If you are using dry-cell batteries, replace with new ones. If the
indicator is still out, consult your nearest Sony dealer.
/
If the AV component headphone jack is connected to the digital surround
processor, raise the volume level on the connected AV component.
