Description

Most of the cars today are equipped with different types of RF emitting devices. One of these devices is the Car Radio-DVD system with Bluetooth connectivity or other type of Bluetooth devices. Bluetooth devices emit RF radiation most of the time. Even when the Car Radio DVD Bluetooth device is not synced to any Bluetooth device, the Bluetooth feature on the car radio emits RF (the Bluetooth scans) every couple of seconds.
