REGION: You can also use the RDS button to access
the region function. When an RDS station becomes
weak, this function searches for a stronger station within
the same network. A network can span a great distance.
One network can have stations spread across a country
or continent. Each network breaks down into regions.
With regions, local news items like weather and traffic
are available to you. When the region function is on, the
radio only searches for stations in the same network and
region. You can only use the region function when RDS
is already on. Press the RDS SELECT button. Then
press and hold the RDS button for two seconds.
REGION: ON will appear on the display. While
REGION: ON appears on the display, press the RDS
button again to turn the region function off. REGION:
OFF will appear on the display. The region function can
be turned on again by pressing the RDS button.
TA (2): Press the RDS SELECT button, followed by
this button to receive traffic announcements. The radio
will turn on the TA display. TP will appear on the
display if the tuned station broadcasts traffic
announcements. You may also receive traffic
announcements from stations in the network related to
the tuned station. If the current tuned station does not
broadcast traffic announcements, the radio will seek to a
station which does. When the radio finds a station which
broadcasts traffic announcements, it will stop. If no
station is found, NONE FOUND will appear on the
display. When SEEK or SCAN is pressed with the
traffic announcement function on, the radio will only
stop at stations which broadcast traffic announcements.
While a traffic announcement plays, the radio uses a
special type of volume called TA volume. To increase
TA volume, turn the PWR/VOL knob clockwise.
Turn it counterclockwise to decrease volume. TA
VOLUME will appear on the display while the
volume is being adjusted.
When a traffic announcement comes on the tuned radio
station or a related network station, you will hear it,
even if the volume is muted or a cassette tape or
compact disc is playing. If the radio tunes to a related
network station for a traffic announcement, it will return
to the original station when the announcement is
finished. If the cassette tape or compact disc player was
being used, the tape or compact disc will stay in the
player and resume play at the point where it stopped.
Press the RDS SELECT button, followed by this button
again to turn TA off.
