Bluetooth
Bluetooth will always default to ON at power up and will look to connect
to the last paired Bluetooth device, except when first powered-on
out of the box in which it will enter discovery mode until a connection
has been made.
To manually toggle Bluetooth connectivity On or Off, press and release the
Bluetooth button on your headphones
the headphones are in AUX listening mode (auxiliary cable is plugged into Symphony 1).
When pairing a new device to Symphony 1, you must put the Symphony 1
into Bluetooth discovery mode. Follow these steps to enter discovery mode:
1) Power on Bluetooth.
2) Press and hold the Bluetooth button on your headphones for 1 second
until the Bluetooth LED begins to pulse slowly. You are now in
discovery mode.
3) The Symphony 1 will search for a connection for up to 90 seconds.
If no connection is found, Bluetooth will automatically turn off.
