This
could
occur
if
RF
energy
is
being
injected
into
the
power
cables
or
by
radiation
injection
into
the
pilot
system
components
at
very
high
levels.
The
autopilot
has
been
exhaustively
tested
to
withstand
RF
injection
and
radiation
at
levels
far
above
those
considered
safe
to
personnel.
Antenna
mismatch
yielding
high
SWR
can
cause
dangerous
conditions
and
in
the
interest
of
operator
safety
the
radio
installation
should
be
inspected
immediately.
A
more
normal
problem
to
occur
is
that
a
Radio
transmitter,
or
other
high
current
unit,
is
being
supplied
from
the
same
battery
as
the
autopilot.
When
the
device
is
operated,
it
may
be
causing
the
battery
voltage
to
drop
below
that
required
to
maintain
the
autopilot
operation.
Once
power
loss
has
occurred,
the
fail-safe
watchdog
has
been
designed
to
stop
the
system
automatically.
This
would
be
particularly
noticeable
if
the
battery
had
a
bad
cell
or
corroded
connections.
It
is
recommended
to
supply
the
autopilot
with
power
from
a
different
battery
to
the
other
auxiliary
requirements.
This
may
happen
very
occasionally
due
to
a
momentary
loss
of
synchronization
during
power
up.
The
self
test
software
reports
all
errors
of
this
type
to
help
anticipate
potential
problems.
Unless
this
happens
repeatedly
it
is
of
little
concern.
securely.
Check
for
any
loose
material
that
may
cause
shorts.
See

and

above.
3.
System
stops
working
for
no
apparent
reason
and
cannot
be
restarted
4.
System
stops
working
when
radio
Transmitter
or
other
RF
device
is
keyed;
or
when
a
device needing
current is operated
(electric
windlass,
etc)
5. The autopilot
powers up but
displays System
Faults which can be
reset and do not
immediately recur
6. The autopilot
powers up but
displays a System
Fault which cannot
be reset.
Normally this can be traced to a wiring error. System fault
messages are explained and action to be taken is given, in
“Error and Fault Messages” after this.
