18、oid thermal damage.The period of time after which the output stages are switched off depends mainlyon the volume setting and the temperature within the car.As soon as the car radio has cooled down, e.g. by reducing the volume level, therear channels are automatically switched on again.Cure:Since thi

19、s behaviour of the radios is not a fault but a built-in safety function, wewould ask you to inform your customers accordingly when complaints are received.Workshop:Please note when complaints are received.CAR AUDIOService InformationProduct:1/1Serial No. 1/99Service Information43189000 (8002/8012) (
