Note before you use Bluetooth:
1. Once your device has been paired to the DMA4100BT, it will remain paired
until the power is turned off, to stream audio the phone or device must be
manually connected to the Bluetooth on the amplifier.
2. When your device and the DMA4100BT are connected, the amplifier will
automatically switch from Line-in (RCA) to BT streaming once a music app is
started (Music player, Internet radio, ECT...)
3. On an incoming phone call is received, the music will pause and resume once
the call has ended, incoming calls will not be transmitted to the amplifier
(Hands-free mode is not supported, only A2DP streaming)
4. To switch back to Line-in (RCA) on the amplifier, all music apps on your
device must be stopped and terminated or Bluetooth must be disconnected.
