The stored stations donot function (no sound,87.5 Mhz is displayed...)

An incorrect waveband is selected.
Press the BAND AST button to return to the waveband (AM, FM1, FM2, FMAST) on which thestations are stored.

The traffi c announcement (TA) is displayed. I do not receive any traffi c information.

Tune to a radio station which broadcasts traffi cinformation. The radio station is not part of the regional traffi c information network.
The quality of receptionof the radio stationlistened to graduallydeteriorates or the stored stations donot function (no sound, 87.5 Mhz isdisplayed...).
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 vehicleis travelling.
The environment (hills, buildings, tunnels, basement car parks...) block reception, including in RDS mode.
The aerial is absent or has been damaged (for example when goingthrough a car wash or into an underground car park).

Activate the RDS function to enable the systemto check whether there is a more powerful transmitter in the geographical area.
This phenomenon is normal and does notindicate a failure of the audio equipment.

Have the aerial checked by a CITROÀN dealer.
Sound cut-outs of1 to 2 seconds in radiomode.
During this brief sound cut-out, the RDS searches for any frequencypermitting better reception of the station.
Deactivate the RDS function if the phenomenonis too frequent and always on the same route.
With the engine off, the audio equipmentswitches off after a few minutes of use.
When the engine is switched off, the audio equipment operating time depends on the battery charge.The switch-off is normal: the audio equipment switches to economy modeand switches off to prevent discharging of the vehicle's battery.
Start the vehicle's engine to increase the batterycharge.
The message "the audiosystem is overheated"appears on the display.

Switch the audio system off for a few minutes to allow the system to cool.In order to protect the installation if the surrounding temperature is toohigh, the audio equipment switches to an automatic thermal protection mode leading to a reduction of the volume or stopping of the playing of the CD.
