Troubleshooting

No sound/Muffled sound

/Check the connection of the audio/video equipment or the AC power adaptor.

/Check that the audio/video equipment is turned on.

/Turn up the volume on the connected audio/video equipment, if the transmitter is connected to the headphones jack. (Around level 5 or 6 on the volume control should be appropriate.)

/The mute function is activated.

•Check if there is any object between the transmitter and the headphones.

•Use the headphones near the transmitter.

•Change the position and angle of the transmitter.

/The headphones’ power indicator light is weak or turned off.

•Replace the battery of the headphones.

/When the LINE OUT jack of your audio/ video equipment is connected to PHONES IN jack of the transmitter, the sound will be low. Connect the LINE OUT jack to the LINE IN jack as described in “Setting up the transmitter”.

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.)

/The headphones’ power indicator light is weak or turned off.

• Replace the battery of the headphones.

/When the headphone’s jack output is connected to the LINE IN jack of the transmitter, increasing the volume of the connected audio/video equipment may cause distortion. Connect the headphones jack output instead to PHONES IN jack as described in “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 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.)

/The headphones’ power indicator light is weak or turned off.

•Replace the battery of the headphones.
