Notes If you use the headphones at too great a distance from the transmitter, you may hear a hissing noise and if there is an object between the receiver and the transmitter, the sound may be interrupted. These phenomena are inherent to infrared ray communication and do not mean that there is a problem with the unit itself. The infrared rays will not penetrate walls or opaque glass, therefore, be sure to stay within sight of the transmitter. When you use the headphones inside the area illustrated in the diagrams, the transmitter can be placed in the front, behind or by the side of the listener.

Distortion

/ If the transmitter is connected to the headphones jack, turn down the volume of the connected audio/video equipment. (Around level 5 or 6 on the volume control should be appropriate.) Replace the battery of the headphones.

Loud background noise

/ Move closer to the transmitter. As you move away from the transmitter, more noise is likely to be heard. This is inherent to infrared ray communication and does not mean that there is a problem with the unit itself. Check that there is no object between the transmitter and the headphones. Check that the infrared sensors are not covered with your hands or hair. Change the position or angle of the transmitter. The headphones are used by a window where the sunlight is too strong. n Draw the curtains/blind to shut out the direct sunlight, or use the headphones away form the sunlight. If the transmitter is connected to the headphones jack, turn up the volume of the connected audio/ video equipment. (Around level 5 or 6 on the volume control should be appropriate.) Replace the battery of the headphones.
