INFO (Information): If the current station has a
message, the information symbol will appear on the
display. Press this button to see the message. The
message may display the artist, song title, call in phone
numbers, etc.
If the entire message is not displayed, parts of the
message will appear every three seconds. To scroll
through the message, press and release the INFO

after every press of the button. Once the complete
message has been displayed, the information symbol
will disappear from the display until another new

the last message until a new message is received
or a different station is tuned to.
When a message is not available from a station,
NO INFO will appear on the display.
