Uniden LRD 737 - Manual (Page 20)

Visual Alert Only Operation
You can operate the LRD 737 in Visual Alert Only by setting the volume
control at the minimum position in Full Alert Mode. At this setting you
can barely hear the audio alert in a quiet environment. Be sure that the
Audio Alert Only indicator is off.
Auto Mute Operation
Press the mute button to activate the Auto Mute feature.
When the Mute indicator is selected, the unit is in Auto Mute Mode. In
this mode you hear the full audio alert when a signal is first received. The
audio alert automatically reduces the volume for the duration of the
warning.
