In the special case of a GPWS Altitude Loss After Take-off alert
(“DON’T SINK”), pressing MUTE will disarm the alert completely
until the next takeoff.
If the MUTE button is pressed when a CAUTION alert is not present,
the text “NO ACTION” will display on the screen.
This function may also be accessed by an optional mounted
pushbutton.
