9. Power
LED
-
If
you have connected your battery power, vehicle
ground, and turn-on
lead
(or
GTO
signal
sensing)
correctly,
then
this
light
should
be green
to
indicate
the
power
is
ON.
An
internal
blue
glow
will also
emanate
from
the
heatsink area
to
indicate
that
the
power
is
ON.
There are times when this
blue
glow
will
flash, such
as
during power-up, and when
the
protection circuits
have detected a
problem.

Protection
LED-
The LC-1.800
amplifier
has
built
in diagnostic
codes
to
tell
you
exactly
what
is
going
wrong
should
the
amplifier
detect
a
problem.
(See
specs page for a
list
of
diagnostic codes.)
If
the
protection
LED
should
come on, read
the
red codes
quickly
before
turning
off
the
system and investigating. Shorts,
like
crushed-velvet
hot
pants, are
not
a
good
thing. Note
that
the
blue
power
codes mentioned in
the
table
are for
the
internal blue
glow
from behind
the
heatsink area, and
not
the
power
LED
which
is
green.
You
might
not
notice
the
subtle blue
glow
at first, unless
you are in
the
dark or
the
shade.

GTO Signal
Sense-
In
the
ON
position,
the
LC-1.800
amplifier will
turn
on
gracefully
when
it
detects
an
incoming audio
signal,
and
it
will
turn
off
after a period
of
time
when
the
audio
signal fades
away
to
silence. In
some situations, factory
installed
audio systems
may
turn
on or
"wake up"
due
to
convenience features
like
door
chimes,
alarms,
and
cell phone signals
that
trigger
the source
unit
in
the
vehicle
to
come on.
To
prevent these from
turning
your
audio system on unexpectedly,
you can bypass the
GTO
circuit by
moving
the
GTO
switch
to
the
OFF
position and
use
a switched
12-volt signal
connected
to
the
Remote
In terminal instead.
