"Pairing" does not have to be repeated. This function may need to be activated in your BT device, however.

• Press [BT select] to enter BT mode.
• Turn on BT streaming on your device. The device will scan for pairable BT devices in the reception range.
• Select "Audizio AD Amplifier" from the list with found devices.
• Start playback on your BT device. Playback now takes place emitting sound from the radio.
