WhileBluetooth compatible devices use a technology minimizing theinfluence of other components using the same radio band, suchinfluence may reduce the speed or distance of communicationsand in some cases interrupt communications.• The speed of signal transfer and the distance at whichcommunication is possible differs according to the distancebetween the communicating devices, the presence of obstacles,radio wave conditions and the type of equipment.• Yamaha does not guarantee all wireless connections betweenthis unit and devices compatible with Bluetooth function.
