Playing a previously-paired Bluetooth source device
The RCR-20 can memorize up to 8 paired Bluetooth source devices,
when the memory exceeds this amount, the earliest paring device will be
over written from the device.
If your Bluetooth source device already paired with the RCR-20 previously,
the unit will memorize your Bluetooth Source device and will attempt to
reconnect with a Bluetooth source device in the memory that was last
connected. If the last connected Bluetooth source device is not available,
the RCR-20 will try to connect to the second last Bluetooth source device.
