USB drive is attached and no Bluetooth device is connected, the controls
will affect the USB interface. In the case where both a Bluetooth device is
connected and a USB drive is attached, the one that is currently active will
have focus from the controls. If neither interface is currently active, the
BTU-2 will focus control on the USB interface by default. In this case to
change focus to the Bluetooth device, momentarily remove the USB drive
or start playback using the menus on the Bluetooth device.
The BTU-2 will always return to the last mode it was in when the
radio was turned off assuming the Bluetooth or USB devices are still
present. For example, if the BTU-2 was playing back from the Bluetooth
or USB when the radio was powered off, it will return to playing back
from where it left off when the radio is turned back on. Additionally, if a
USB drive is inserted after the the radio is turned on, the BTU-2 will start
playback of the USB drive unless the Bluetooth interface is currently
active.
The BTU-2 supports
Voice Assist
which will speak messages to you in
English, Spanish or French to assist in the operation of the radio.
Bluetooth Pairing
:
To pair a new device, twist the volume control
back and forth twice towards the direction of higher volume. (this is the
same action that is used with the tone control to access the virtual fader
function) or push and hold the optional pushbutton. The optional front
panel status LED or the optional pushbutton LED will flash and a
Voice
Assist
message will be heard in the radio. The BTU-2 will then go into
pairing mode for approximately 90 seconds or until a device is paired.
While in pairing, the BTU-2 will display as
AuroraDesign BTU-x.x
in the
Bluetooth section of your device. (x.x represents the version) Select the
BTU-2 to connect. (refer to the owners manual for your Bluetooth device
for information on pairing) If you wait longer than 90 seconds the BTU-2
will time out and
Voice Assist
message will be heard. Up to eight devices
can be paired to the BTU-2.
Bluetooth Connecting
:
The BTU-2 will automatically attempt to
reconnect to the last connected Bluetooth device. If this device is not
within range, the BTU-2 will then attempt to reconnect to any of the last
four connected devices. This is handy when the user has multiple
Bluetooth devices, or several people use the radio. If any paired device is
within range when the radio is powered on, the BTU-2 will reconnect and
return to its last mode. The optional front panel LED or the optional
pushbutton LED will illuminate to signify a Bluetooth device is connected.
A
Voice Assist
message will also be heard in the radio when a Bluetooth
device successfully connects.
Bluetooth Name
:
To change the name of the BTU-2 from the default
AuroraDesign BTU-x.x,
create a simple text file on a computer named
BTU_NAME.TXT. In this file, enter the desired name, up to 32 characters
long. Names such as
Darryls’ 65 Mustang
will personalize your radio and
make it easier to identify if you own multiple FMR/BTU radios. Place this
file on a USB drive and connect to the BTU-2. The BTU-2 will update its
name and a
Voice Assist
message will be heard.
Bluetooth Audio Levels
:
The BTU-2 sends commands to the
connected Bluetooth device to adjust the playback audio levels, but many
devices require that the user make these settings manually. Usually the
playback levels for audio streaming, phone calls and
Voice Command
are
all stored separately so must be adjusted separately. The first time you
stream audio, take a phone call, or use the
Voice Command
feature, use the
volume buttons or volume slider menu on the device to adjust the audio
level. This only needs to be performed once on the device as these settings
are permanently saved in the device.
Bluetooth
Voice Command
:
The Bluetooth
Voice Command
feature
allows the user to control their compatible Bluetooth device through voice
commands. The
Voice Command
feature is accessible in all radio modes. It
is designed to work with Apple Siri
®
, Google Voice
®
and Microsoft
Cortana
®
and other Bluetooth voice interfaces. To initiate a
Voice
Command
, twist the volume control back and forth twice towards the
direction of higher volume or push and hold the optional pushbutton. (this
is the same motion that was used to open up pairing) Wait for the
confirmation tone from the Bluetooth device and then speak the command.
For example you can say things like “call home” or “play Bruce
Springsteen”. Check with the manual for your Bluetooth device for further
information on its support for voice commands.
Bluetooth/USB Streaming Audio:
To start playing music from
either the Bluetooth or USB interface, twist the volume control back and
forth twice towards the direction of lower volume or push and hold the
optional push button for about 1 second. (you can also use the menus on
your Bluetooth device to control the audio) Audio will start playing from
the device that has focus as explained above. To toggle between pause and
play, repeat the procedure above. When the audio is paused, the FMR-2
status LED will blink slowly. If the audio is paused for more than about 10
seconds, the BTU-2 will release the FMR-2 and it will switch back to
normal radio operation. If playback is started again, it will continue from
where it left off.
For the USB interface, if the BTU-2 remains in pause for more than 10
minutes, when playback is resumed, the USB will start playing the last
song from the beginning rather than from where it left off. Additionally to
change the operating mode of the USB interface between random and
sequential playback, start by placing the USB interface in pause as
described above. To select random playback, twist the tuning control
towards the high frequency end of the dial or quickly press the optional
pushbutton once. A
Voice Assist
message will confirm the setting. To select
sequential playback, twist the tuning control towards the low frequency
