The reception quality of the radio station being listened to gradually deteriorates or the pre-set stations do not work (no sound, 87.5 Mhz displayed, etc.).
The vehicle is too distant from the transmitter of the station being listened to, or no transmitter is present in the geographical area you are passing through.
Activate the RDS function to allow the system to check whether a more powerful transmitter is to be found in the geographical area.
The environment (hills, high buildings, tunnels, underground car parks, etc.) is blocking reception, even in RDS mode.
This phenomenon is normal and does not imply anything wrong with the radio.
The aerial is absent or has been damaged (for example after going through a car wash or in an underground car park).

Cutting of sound for 1 or 2 s e c o n d s i n r a d i o m o d e .
The RDS system during this brief sound cut-off is searching for a better frequency that might offer improved reception of the station.
Deactivate the RDS function if the phenomenon occurs too frequently and always on the same journey.
When the engine is not running, the radio stops after a few minutes.
When the engine is switched off, the working time for the radio depends on the vehicle battery charge.
The interruption is normal: the radio goes into economy mode, cutting off in order to save the vehicle’s battery.
You have to start the engine so as to increase the battery charge.
The message "the audio system is overheating" appears on the screen.
In order to protect the audio equipment in excessive ambient temperatures, the radio goes into an automatic thermic protection mode which results in a reduction in sound volume or stopping of the CD player.
Switch off the audio system for a few minutes in order to allow the system to cool down.
