TRAF (Traffic) function: A station that regularly
broadcasts traffic information is automatically located
and broadcasts when the program starts.
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. However, if the "TRAF" button is pushed while
in "TAPE" or "CD" mode, the radio will start seeking traffic
program stations again after 20 seconds.
If a traffic program station is found, the name for traffic program
station is displayed for a while until a traffic announcement is
received. On reception of a traffic announcement, you will hear
a beep and "TRAF ANNOUNCE" appears on the display for a
few seconds.
After the traffic announcement program is over, a beep sounds
and the display returns to the previous mode.
TA volume level: The volume of the traffic information
program can be adjusted independently by turning the
"POWER VOL" knob while a traffic program station is received.
