press th unmute button

To unmute, follow the steps

• Click on Start
• Go to Control Panel
• Double click on Sound

A window will appear where you can adjust sound levels and different option. From there, you can click on the red circle again and unmute it.

there should be a button with att on it. try pressing that. (att is short for attenuation.)

does the mute symbol appear anywhere on the radio? If not it may be something internal, like the signal processor's gone bad. What model is it? does turning up the volume help? If it's aftermarket, it may have a reset button behind the faceplate.

U should check the line in volume. go to control panel-sound and audio-recording devices-line in properties-and then unmute from here. If already unmuted then check out that ur microphone properties has enable listen audio on ur speakers.

one of the units may have a bad mic element. Can you hear the speaker unmute when the radio is keyed?
