The
operator
should
carry
out
the
actions
called
for
in
the
prepared
test
sequence.
NOTE
It
is
important
that
all
actions
are
carried
out
in
the
order
and
at
the
precise
elapsed
time
as
specified
in
the
prepared
test
sequence.
10.
When
the
actions
in
the
test
sequence
have
been
completed,
press
the
ENTER
button
to
indicate
that
the
process
is
complete.
When
this
is
done,
the
TEST
COMPLETE
field
stops
blinking.
11.
The
PFD
informs
the
operator
if
the
installation
has
passed
or
failed
the
magnetometer
interference
test.
If
the
test
passes,
no
further
action
is
required
for
this
test.
12.
If
the
test
fails,
the
installation
should
be
considered
unreliable
until
the
source
of
magnetic
interference
is
identified
and
remedied.
When
the
magnetometer
interference
test
fails,
record
the
three
magnetometer
maximum
deviation
values
and
their
corresponding
timestamps.
Any
maximum
deviation
value
greater
than
2.5
milliGauss
indicates
a
problem
that
must
be
resolved.
Compare
the
corresponding
timestamps
with
the
prepared
test
sequence
to
identify
which
action
produced
the
problem.
Contact
Garmin
for
assistance
in
resolving
the
problem.
NOTE
Two
common
reasons
for
a
failed
magnetometer
interference
test
are:
new
equipment
is
installed
in
close
proximity
to
the
GMU
44
magnetometer,
and
an
existing
or
new
electronic
device
has
become
grounded
through
the
aircraft
structure
instead
of
via
the
proper
ground
wire
in
a
twisted
shielded
pair.
13.
Press
the
ENT
key
on
the
PFD
to
conclude
this
procedure.
