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 in 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.

,If you use the headphones by a window where the sunlight is too strong, draw the curtains/blinds to shut out the direct sunlight, or use the headphones away from the sunlight.

,Change the position or angle of the transmitter.

,If the transmitter is connected to the headphones jack, raise the volume of the audio/video equipment connected to the transmitter.

,The headphones’ power indicator light dims, flashes or goes off.

Charge the rechargeable batteries if the headphones’ batteries are weak, or replace dry batteries with new ones. If the power indicator is still off after charging the batteries, take the headphones to a Sony dealer.

,When you have another transmitter, check if more than one transmitters are used at the same time.

Turn off other transmitter or move to a place outside the range of this transmitter.

The batteries cannot be charged

,Check if the charging indicator light is on. If not, put the headphones on the transmitter correctly so that the charging indicator light is on.

,Dry batteries are installed.

Install the supplied rechargeable nickel-metal hydride batteries.

,Rechargeable batteries other than the supplied are installed.

Install the supplied rechargeable nickel-metal hydride batteries.
