AUDIO SYSTEM
EON (Enhanced Other Network) system
— If the RDS station (with EON data)
you are listening to is not broadcasting
a traffic information program in the TA
(Traffic Announcement) mode, the radio
will be switched to the traffic information
program automatically by using the EON
AF list. After the traffic information ends,
the radio will return to the initial program
automatically. One beep will sound to
tell you when this feature starts and ends
operation.
When listening to the audio system in
another mode: With the "TA" touched in
another audio mode, a station broadcasting
traffic information is sought and "TA"
appears on the screen.
When the traffic information program
starts, any other audio mode is interrupted
and the traffic information is automatically
broadcasted. When the program ends, the
initial operation resumes.
"TA VOL" (Traffic Announcement Volume)
function: The volume level when receiving
the traffic announcement is memorized.
When "TA" is received next time, the
system compares the volume before "TA"
is received and the memorized TA volume
and automatically selects the louder
volume. However, the range of volume
memory is limited: if the volume received
previously is less than the minimum, this
volume will be used.

"ALARM" (Emergency broadcasting)
This type of announcement warns of
national or local emergencies. You will not
be able to turn off alarm announcements.
Alarm announcements will come on even
if RDS mode is turned off. "ALARM"
appears on the display when an alarm
announcement plays.
TA volume during these announcements.
When an alarm announcement comes on
the tuned radio station or a related network
station, you will hear it even if the volume
is muted or another audio mode is being
played. If the radio tunes to a related
network station for an alarm announcement,
it will return to the original station when the
announcement is finished. If another audio
mode is being played, play will stop for
the announcement and resume when the
announcement is finished.
When "TA" is received next time, the
system compares the volume before "TA"
is received and the memorized TA volume
and automatically selects the louder
volume. However, the range of volume
memory is limited: if the volume received
previously is less than the minimum, this
volume will be used.
You can adjust the volume independently
from the memorized TA volume range
while receiving a TA station.
Traffic announcement can be canceled by
turning RDS off, or touching the "TA" again
on the "SOURCE" screen.
