Volume adjusting mode
The M17 uses the volume knob for adjusting the volume by default. The volume button could
not adjust the volume at that time. You could switch this option to 'Adjust by volume button'
and the volume button could adjust the volume now. Please select the option according to
your need.
In-vehicle mode
【Principle】After turning on the In-vehicle mode, you can connect the USB 3.0 port of M17 to
the on-board USB port. And the M17 will power on automatically and switch to the In-vehicle
mode screen when the vehicle engine starts, and power off automatically when the vehicle
engine stops.
【How to set】Go to Settings->Global->In-vehicle mode, or the drop-down menu to turn on the
in-vehicle mode.
(Some onboard USB ports may encounter interruptions when connecting to the M17, in
which case you can try to use FiiO's USB isolator, the LA-UA1, to fix the problem.)
