TROUBLESHOOTING 

NO SOUND 

-

 

Ensure that the AC power adapter is pushed fully into the power outlet and 

that its cable is properly connected to the DC IN 12V connector on the 

transmitter. 

-

 

Ensure that the headphones On/Off switch is in the On position. 

-

 

The headphones battery charge level may be too low. Recharge the 

batteries or replace them with fully charged batteries. 

-

 

Ensure your TV set, stereo system, VCR, DVD player or audio component 

is switched on and set to a channel that broadcasts an audio signal. 

-

 

The connected audio/video equipment may not be in playback mode. Start 

playback on the equipment. 

-

 

Ensure the source is broadcasting at a sufficient volume by increasing the 

volume as needed on the source component. Use the headphones volume 

control to increase the sound level. 

-

 

Check the battery compartments to ensure batteries are fully seated and 

that polarity positions are correct. 

DISTORTION 

-

 

Ensure that the "Stereo" indicator is lit. If not, press the autoscan button on 

the headphones until it illuminates. 

-

 

Use the channel selector to change the transmitter's frequency. Press the 

auto tune button on the headphones until the "Stereo" indicator comes on. 

-

 

The headphones battery charge level may be too low. Recharge the 

batteries or replace them with fully charged batteries. 

-

 

The headphones may be too far away from the transmitter. Move to a 

location closer to the transmitter. 

-

 

The audio signal input level may be too low. Increase the volume from the 

audio  source.

FOR MAXIMUM PERFORMANCE 

When available, a variable output on the source component will offer increased volume 

control and help reduce distortion. Examples of variable outputs are headphone jacks, 

computer speaker outputs and some TV RCA output jacks.  

a.  When using a variable output jack, set the volume of the source 

component to mid-level and adjust headphone volume control until 

desired result is achieved. If headset volume is not sufficient, adjust 

source volume. If distortion in the headset occurs, reduce volume 

control on source component. 

b.  Fixed outputs allow for volume regulation through the headset only. 

Examples of fixed outputs are RCA jacks (VCR, Tape, Video or CD 

outputs).
