treVolo U
does not
automatically
switch to

In the case of connecting speaker with audio cable
the analog audio signal cannot be detected and
switched automatically to HFP (Hands-Free Profile)
which can be detected digitally under Bluetooth
connection.
You can manually switch the mode to Live Learning
to improve the quality of the course. See The three
Sound Modes on page 12.
When using a
PC to

"U XXXX"
will be shown
on the
Bluetooth
setting
connection
screen.
When using a PC as the source device, please select
"treVolo U XXXX" as the device to connect to.
"U XXXX" is provided as the Bluetooth interface
(BLE) used by the App.
• treVolo U XXXX: for Bluetooth speaker
connection
• U XXXX: for treVolo U App connection
(Connecting only this mode will not transmit audio
sound.)
When
connecting an
iOS device to
the speaker
via Bluetooth,
the Bluetooth

two identical

headings.
There will be two treVolo U headings on the
Bluetooth connection page, as one is for the

one is for the treVolo U App. Please select and
connect both in order to use the speaker and the
