8.Typical faults and solutions
GT
‐
RK1
GPS
repeater
fault
location
and
remove:
First:
Check
the
adapter
of
GA30
‐
V,
whether
it
connects
to
the
power
supply
and
power
‐
up
to
GA30
‐
V
as
GA30
‐
V
hasn’t
power
light.
You
can
test
the
voltage
between
input
axis
and
shell,
if
it’s
about
5V,power
supply
was
ok,GA30
‐
V
was
also
works
ok.
Or
else,
check
the
power
socket
to
assure
the
contact
was
ok.
Second:
If
it’s
5V
at
the
input
of
Gain
Controller,
you
need
to
check
whether
the
fixing
is
steady
between
GAT10
and
the
cable.
Third:
If
the
below
two
step
were
ok,
please
check
the
outdoor
antenna
Timing4000.You
can
screw
the
port
which
connect
Timing4000
and
cable(carefully
screw,
not
unplug
strongly).Notice:
when
screwing
the
cable
connector,
you
should
make
sure
to
screw
the
iron
pipe,
maintain
the
antenna
and
cable
moveless,
which
avoid
to
screw
off
the
cable.
After
riving,
check
the
voltage
between
axis
of
the
cable
connector
and
the
outer
shielding
layer
to
make
sure
it’s
5V.If
no
voltage,
the
circuit
has
fault,
please
contact
our
technical
support.
If
5V,the
antenna
Timing4000
can
be
suspected.(In
fact,
this
case
hasn’t
appear
in
our
engineering
projects.
