RADIO INTERFERENCE
The AV8 is a digital audio device which have been designed to very high standards of electromagnetic compatibility.
The unit can radiate RF (radio frequency) energy. In some cases this can cause interference with FM and AM radio reception. If this is the case, keep the AV8 player and its connecting cables as far from the tuner and its aerials as possible. Connecting the AV8 and the tuner to different mains sockets can also help to reduce interference.
