QUESTIONANSWER SOLUTION
There is a difference in sound quality between
the different audiosources (radio, CD...).
For optimum sound quality, the audio settings
(Volume, Bass, Treble,
Ambience, Loudness) can be adapted to the different sound sources,
which may result in audible differences when changing source (radio,
CD...).
Check that the audio settings (Volume, Bass,
Treble, Ambience, Loudness) are adapted to
the sources listened to. It is advisable to set
the AUDIO functions (Bass, Treble, Front-Rear Fader, Left-Right Balance) to the middle position, select the musical ambience "None" and set theloudness correction to the "Active" position in CD mode or to the "Inactive" position in radio mode.
When chan
ging the settings for treble andbass, the ambience setting is deselected.

When changing the
ambience setting, treble
and bass are reset to zero.Choosin
g an ambience imposes settings for treble and bass. Modifyingone without the other is not possible. Modify the treble and bass settings or the
ambience setting to obtain the desired sound quality.

When changing the balance setting, distribution is deselected.
Choosing a distribution setting imposes a balance setting. Modifying one
without the other is not possible. Modify the balance setting or the distribution setting to obtain the desired sound quality. The
following tables contain answers to the most frequently asked questions.

The quality of receptionof 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 dama
ged (for example when goingthrough a car wash or into an underground car park). Have the aerial checked by a CITROËN dealer.

Sound cut-outs of 1 to2 seconds in radio mode.During this brief sound cut-out, the RDS searches for any frequency
permitting better reception of the station. Deactivate the RDS function if the phenomenon is
too frequent and always on the same route.
Th
e traffi c announcement(TA) is displayed. I donot receive any traffi c
information.Th
e radio station does not broadcast traffi c information. Tune to a radio station which broadcasts traffi c
information.

The Apple ®player is of a generation that is not compatible with the USB. Connect the Apple ®player to the AUX Jack socket using a suitable cable (not supplied).
Th
e hard disk or deviceis not recognised whenconnecting to the USBport. Some hard disks and devices need a power suppl
y greater than is
provided by the audio system. Connect the device to the 230 V socket, the 12 V socket or an external power supply.
Caution
:
ensure that the device does not transmit
a voltage greater than 5 V (risk of destruction of
the system).
When streamin
g, the sound cuts momentarily. Some telephones prioritise connection of the "hands-free" profi le. Delete the "hands-free" connection profi le toimprove streaming.

With the en
gine off, the
audio system switches off after a few minutes of use. When the en
gine is switched off, the audio system operating timedepends on the battery charge.
The switch-o
ff is normal: the audio system switches to economy mode and switches off to prevent discharging the vehicle's battery. Start the vehicle's en
gine to increase the batterycharge.
The messa
ge "the audio system is overheated"
appears on the display. In order to protect the installation if the surroundin
g 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 s
ystem off for a few minutes to
allow the system to cool.
