The
 
quality   of   reception  
of

 
the
 
radio   station  
listened

  to   gradually  
deteriorates

  or   the   stored  
stations

  do   not   function  
(no

 
sound,   87.5 MHz   is  
displayed...). The

  vehicle   is   too   far   from   the   transmitter   used   by   the   station   listened  
to

  or   there   is   no   transmitter   in   the   geographical   area   through   which   the  
vehicle

  is   travelling. Activate
  the   RDS   function   to   enable   the   system  
to

  check   whether   there   is   a   more   powerful  
transmitter

  in   the   geographical   area.
The
  environment   (hills,   buildings,   tunnels,   basement   car   parks...)   block  
reception,

  including   in   RDS   mode.This
  phenomenon   is   normal   and   does   not   indicate  
a

  failure   of   the   audio   equipment.
The
  aerial   is   absent   or   has   been   damaged   (for   example   when   going  
through

  an   automatic   car   wash   or   in   an   underground   car   park).Have
  the   aerial   checked   by   a   CITROËN   dealer.
Sound
  cut-outs   of   1   to  
2 seconds

  in   radio   mode.During
  this   brief   sound   cut-out,   the   RDS   searches   for   another   frequency  
giving

  better   reception   of   the   station.Deactivate
  the   RDS   function   if   the   phenomenon   is  
too

  frequent   and   always   on   the   same   route.
The
 
traffic   announcement  
(T

is
  displayed.   I   do  
not

 
receive   any   traffic  
information. The

  to   a   radio   station   which   broadcasts   traffic  
information.

With
 
the   engine   off,   the  
audio

 
system   switches  
of

f
 
after   a   few   minutes  
of

 
use. When
  the   engine   is   switched   off,   the   audio   system   operating   time  
depends

  on   the   battery   charge.
The
  switch-off   is   normal:   the   audio   system   switches   to   economy   mode  
and

  switches   off   to   prevent   discharging   the   vehicle's   battery.Start
  the   vehicle's   engine   to   increase   the   battery  
charge.
The

 
message   "the   audio  
system

  is   overheated"  
appears

  on   the   display. In
  order   to   protect   the   installation   if   the   surrounding   temperature   is   too  
high,

  the   audio   system   switches   to   an   automatic   thermal   protection   mode  
leading

  to   a   reduction   of   the   volume   or   stopping   of   the   playing   of   the   CD.Switch
  the   audio   system   off   for   a   few   minutes   to  
allow

  the   system   to   cool.
