[FM Band Only]
You can turn FM Muting ON to silence your radio as you tune
frequencies where either no station exits or the station that
is using that frequency is weak. Muting eliminates the noise
unless the level of the signal is sufcient for comfortable
listening.
Select the FM band. Press MENU.
Use ▲ or ▼ to FM Muting. Press ENTER to select it.
Use ▲ or ▼ to choose either On to enable muting,
Off to disable a previously set muting on condition or
Exit to take no action. Press ENTER.
With muting on, as you tune through the FM band, the usual
noise from weak or unassigned frequencies in your area will
be silenced.
