SOLUTION


A telephone connects
automatically,
disconnecting another
telephone. Automatic connection overrides manual connection. Modify the telephone settings to remove automatic
connection.
An IPod is not recognised
when connecting to the
USB port. The IPod is of a generation that is not compatible with the USB. Connect the IPod to the AUX Jack socket using a
suitable cable (not supplied).
The hard disk or device
is not recognised when
connecting to the USB
port. Some hard disks and devices need a power supply 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 streaming, the
sound cuts momentarily. Some telephones prioritise connection of the "hands-free" profi le. Delete the "hands-free" connection profi le to
improve streaming.
In "Random all" play,
not all of the tracks are
played. In "Random all" play, the system can only take into account up
to 999 tracks.
With the engine off, the
audio system switches
off 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.
