the audio/video equipment connected

to the transmitter.

, The headphones’ power indicator light

dims, flashes or goes off.

the power indicator is still off after

charging the battery, take the

headphones to a Sony dealer.

your connected equipment to the LINE

IN jack of the transmitter, sound may

be distorted when raising the volume.

Use the PHONES IN jacks of the

transmitter instead. See “Setting up the

transmitter.”

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.)

the transmitter and the headphones.

, Check that the infrared sensors are not

covered with your hands or hair.

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.

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 battery if

the headphones’ battery is weak, or

replace dry battery with new ones. If

the power indicator is still off after

charging the battery, 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 battery cannot be

charged

on. If not, put the headphones on the

transmitter correctly so that the

charging indicator light is on.
