Charging
the
Device
We
recommend
that
you
fully
charge
the
battery
prior
to
first
use.
A
high
power
USB
port
is
provided;
we
recommend
that
this
is
used
to
charge
the
device.
When
a
charger
is
connected,
the
charging
LED
on
the
device
gives
a
visual
indicator
of
the
state
of
charge:
Green
LED
Green
indicates
that
the
battery
is
fully
charged
(100%)
Red
Solid
LED
Red
Solid
LED
indicating
Battery
is

In
rare
cases,
during
use,
the
battery
may
discharge
to
a
very
weak
state.
In
such
a
state,
when
a
user
attempts
to
turn
on
the
device
using
the
power
button,
the
device
may
not
respond.
To
recover
from
this,
connect
the
charger
to
the
device.
The
LED
will
then
glow
red,
and
stay
that
way
for
a
few
minutes.
The
device
will
then
boot
into
charging
mode.
