TRAF (Traffic) function: A station that regularly
broadcasts traffic information is automatically located.
When you push the "TRAF" button, "TRAF SEEK" appears on
the display and the radio will start seeking any traffic program
station.
If no traffic program station is found, "NO TRAF INFO" appears
on the display for a few seconds and the display returns to the
previous mode.
Radio text message:
If the radio receives a radio text message during FM reception,
"MSG" and a text message appears on the display. After the
text message goes off, "MSG" also goes off.
After the text message goes off from the display, pushing the
"MSG" button during message reception shows the text
message again on the display.
The RDS audio system can store three messages consisting
of 64 characters in memory. To store a message in memory,
push the "MSG" button until you hear a beep.
If three messages are already stored in memory, the oldest
message will be overwritten by the new message.
