RDS
RDS, if displayed, enables you to continue listening to the same station
by automatic retuning to alternative frequencies. However, in certain
conditions, coverage of an RDS station may not be assured throughout
the country as radio stations do not cover 100 % of the territory. This
explains the loss of reception of the station during a journey.
When the radio is displayed on the
screen, press OK to display the
contextual menu.
Select " RDS " and confi rm to save.
" RDS " is displayed in the screen.
Receiving TA messages
The TA (Traffi c Announcement) function gives priority to TA alert
messages. To operate, this function needs good reception of a
radio station transmitting this type of message. When a traffi c
report is transmitted, the current audio source (Radio, CD,
USB, ...) is interrupted automatically to play the TA message.
Normal playback of the audio source resumes at the end of the
transmission of the message.
Press TA INFO to activate or deactivate
the reception of traffi c messages.
