"Auto Muting" in the context of FM means the output will be muted if the signal is so weak it would result in mostly noise anyway. Interstation radio noise can be annoying and dangerous at high volumes.

Try this: • PRESS PROGRAM • DIAL ** • DIAL 1234 (SYSTEM PASSWORD) • DIAL 000 (DATE AND TIME PROGRAM NUMBER) • PRESS THE NEXT KEY • ENTER THE YEAR • PRESS THE ARROW (FWD/DND) KEY • PRESS THE SELECT (AUTO ANSW/MUTE) KEY UNTIL DESIRED MONTH IS DISPLAYED • PRESS THE ARROW (FWD/DND) KEY • ENTER THE DAY OF THE MONTH • PRESS THE ARROW (FWD/DND) KEY • PRESS THE SELECT (AUTO ANSW/MUTE) KEY UNTIL THE CORRECT DAY OF THE WEEK IS DISPLAYED • PRESS THE STORE KEY • PRESS THE NEXT KEY • ENTER THE HOUR • PRESS THE ARROW (FWD/DND) KEY • ENTER THE MINUTES • PRESS THE ARROW (FWD/DND) KEY • PRESS THE SELECT (AUTO ANSW/MUTE) KEY FOR AM OR PM • PRESS THE ARROW (FWD/DND) KEY • PRESS THE SELECT (AUTO ANSW/MUTE) KEY FOR A 12 OR 24 HOUR CLOCK • PRESS THE STORE KEY • PRESS THE END (HOLD) KEY • PRESS THE PROGRAM KEY TO EXIT PROGRAMMING

"Auto Muting" is for FM reception only and means it will mute the FM audio unless the signal is strong enough to provide decent audio.

Re-evaluate your symptom and corrective actions for relevancy.

From the remote control ONLY:

Press MUTING to mute the sound through all

speakers and headphones connected.

"MUTING" appears on the display and the

volume turns off (the volume level indicator goes

off).

To restore the sound, press MUTING again so that "OFF" appears

on the display.

• Turning MASTER VOLUME on the front panel or pressing
VOLUME +/- on the remote control also restores the sound.

That's normal.

The Auto Muting mode mutes the audio output of the tuner if the station is not sufficciently strong to be accurately tuned. Otherwise you would hear all that interstation hash noise.

Press the FM Mode button to change it to Mono if you want to manually tune a hard-to-reach station. It will be in Mono.

AUTO MUTING Normally select this.
When a program is broadcast in stereo, you will hear stereo sound; when in monaural, you will hear monaural sound.
This mode is also useful to suppress static noise between stations. The AUTO MUTING indicator lights up on the display.

I had same problom and fixed by connecting an antenna to fm port
