AUTO MUTE/AUTO MUTE VOLUME
When the R4BLK detects a signal, it sounds an alarm at the current volume level. To
make the alarm quieter, turn Auto Mute on through the menus (see page 22). This
will reduce the volume to the level set (0 - 7) in the Auto Mute Volume menu (see
page 22).
If the current volume level is 0, the R4BLK will not change the volume to the Auto
Mute Volume level; it will keep the volume level at 0.
Auto Mute ends 10 seconds after the alarm ends unless:
• The same signal is detected within that 10 second period; then, Auto Mute stays
on.
• A different band signal is detected during that 10 second period; then, Auto Mute
turns off and then back on at the current volume level.
Auto Mute does not apply to Laser Alert.
