RDS Messages
ALERT!: This type of announcement warns of national
or local emergencies. You will not be able to turn off alert
announcements. ALERT! appears on the display when an
alert announcement plays. When an alert announcement
comes on the current radio station, you will hear it, 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 for the announcement and
resume when the announcement is finished.
This function will only work during actual emergency
broadcasts, and will not work during tests of the
emergency broadcast system. This feature is not
supported by all RDS stations.
INFO (Information): If the current station has a
message, INFO will appear on the display. These text
messages are from the RDS broadcaster to the listening
public and may be general information such as artist and
song title, call in phone numbers, etc. Press this button to
see the message. If the whole message does not appear on
the display, parts of the message will appear every three
seconds until the message is completed. To scroll through
the message at your own speed press the INFO button
again for less than one second. A new group of words
will appear on the display. Once the complete message
has been displayed, INFO will disappear from the display
until another new message is received.
3-24
The old message can be displayed by pressing the INFO
button until a new message is received or a different
station is tuned to. If the INFO button is pressed when
INFO is not displayed and an old message has not been
stored by the radio, the radio will display NO INFO.
TRAF (Traffic): Press this button to receive traffic
announcements. The traffic announcement brackets will
appear on the display. TRAF will appear on the display
if the current station broadcasts traffic announcements.
If the current station does not broadcast traffic
announcements, the radio will seek to a station that
does. When the radio finds a station that broadcasts
traffic announcements, it will stop. TRAF will appear on
the display. If no station is found, NO TRAFFIC will
appear on the display.
Your radio can be programmed to interrupt the playback
of a CD, cassette or FM radio by enabling the traffic
interrupt feature. Press the TRAF button once to turn on
the traffic feature, if supported by the current RDS
station. If the station does not support the traffic
interrupt feature, the radio will search for an RDS
station that does support the feature. When the traffic
interrupt feature is on, TRAF will appear on the display.
