HX400
Alignment
The
HX400
has
been
carefully
aligned
at
the
factory
for
the
specified
performance
across
the
marine
and
LMR
bands.
Realignment
should
therefore
not
be
necessary
except
in
the
event
of
a
component
failure.
All
component
replacement
and
service
should
be
performed
only
by
an
authorized
STANDARD
HORIZON
representative,
or
the
warranty
policy
may
be
voided.
The
following
procedures
cover
the
sometimes
critical
and
tedious
adjustments
that
are
not
normally
required
once
the
transceiver
has
left
the
factory.
However,
if
damage
occurs
and
some
parts
are
replaced,
realignment
may
be
required.
If
a
sudden
problem
occurs
during
normal
operation,
it
is
likely
due
to
component
failure;
realignment
should
not
be
done
until
after
the
faulty
component
has
been
replaced.
We
recommend
that
servicing
be
performed
only
by
authorized
STANDARD
HORIZON
service
technicians
who
are
experienced
with
the
circuitry
and
fully
equipped
for
repair
and
alignment.
Therefore,
if
a
fault
is
suspected,
contact
the
dealer
from
whom
the
transceiver
was
purchased
for
instructions
regarding
repair.
Authorized
STANDARD
HORIZON
service
technicians
realign
all
circuits
and
make
complete
performance
checks
to
ensure
compliance
with
factory
specifications
after
replacing
any
faulty
components.
Those
who
do
undertake
any
of
the
following
alignments
are
cautioned
to
proceed
at
their
own
risk.
Problems
caused
by
unauthorized
attempts
at
realignment
are
not
covered
by
the
warranty
policy.
Also,
STANDARD
HORIZON
must
reserve
the
right
to
change
circuits
and
alignment
procedures
in
the
interest
of
improved
performance,
without
notifying
owners.
Under
no
circumstances
should
any
alignment
be
attempted
unless
the
normal
function
and
operation
of
the
transceiver
are
clearly
understood,
the
cause
of
the
malfunction
has
been
clearly
pinpointed
and
any
faulty
components
replaced,
and
the
need
for
realignment
determined
to
be
absolutely
necessary.
The
following
test
equipment
(and
thorough
familiarity
with
its
correct
use)
is
necessary
for
complete
realignment.
Correction
of
problems
caused
by
misalignment
resulting
from
use
of
improper
test
equipment
is
not
covered
under
the
warranty
policy.
While
most
steps
do
not
require
all
of
the
equipment
listed,
the
interactions
of
some
adjustments
may
require
that
more
complex
adjustments
be
performed
afterwards.
Do
not
attempt
to
perform
only
a
single
step
unless
it
is
clearly
isolated
electrically
from
all
other
steps.
Have
all
test
equipment
ready
before
beginning,
and
follow
all
of
the
steps
in
a
section
in
the
order
presented.
