manually.
Receiving emergency
announcements
With AF or TA on, the emergency
announcements will automatically interrupt the
currently selected source.
Tip
If you adjust the volume level during a traffic
announcement, that level will be stored into memory
for subsequent traffic announcements, independently
from the regular volume level.
