RDS Messages
ALERT!: Alert warns of local or national emergencies.
When an alert announcement comes on the current radio
station, ALERT! will appear on the display. You will hear
the announcement, even if the volume is muted or a
cassette tape or a compact disc is playing. If the cassette
tape or compact disc player is playing, play will stop
during the announcement. You will not be able to turn off
alert announcements.

ALERT! will not be affected by tests of the emergency
broadcast system. This feature is not supported by all
RDS stations.

message, INFO will appear on the display. Press this
button to see the message. The message may display
the artist and song title, call in phone numbers, etc.

will appear every three seconds. To scroll through the
message at your own speed, press the INFO button
repeatedly. A new group of words will appear on
