If
GPS
Signal
Is
Lost
If
the
GPS
signal
is
lost
the
DG
will
enter
the
free
gyro
mode.
This
mode
has
no
track
or
heading
reference
so
the
DG
must
be
set
against
a
compass
heading
or
other
directional
reference.
There
are
several
options
for
changing
the
DG
direction.
1-­‐To
stop
the
DG
from
drifting
left,
press
and
hold
the
‘control
key’
and
to
the
right
of
the
DG
box.
The
longer
these
keys
are
held
the
more
the
drift
will
be
reduced.
2-­‐To
stop
the
DG
from
drifting
right,
follow
the
same
procedure
as
in
1,
but
touch
to
the
left
of
the
DG
box.
Once
the
drift
has
been
removed
(DG
stopped),
the
following
procedure
can
be
used
to
set
the
DG
value.
1-­‐Hold
the
key
on
the
side
of
the
DG
box
that
corresponds
to
the
desired
DG
direction.
The
longer
it
is
held,
the
faster
the
DG
will
move.
Release
the
key
when
the
desired
value
is
displayed
in
the
box.
