The
programming
of
IR
code
：
There
are
>10
types
of
DVD,
NAVI,
and
Tuners’
IR
code
are
stored
inside
the
interface.
The
installer
just
adjusts
the
options
to
select
to
wanted
one,
then
it
works.
If
the
wanted
type
is
not
there,
he
may
set
the
option
to
be
“Prog”
in
the
menu.
When
programming,
switch
the
input
to
AV1,
and
set
DIP6
down
once,
then
the
control
icons
will
be
shown,
and
one
of
the
them
will
be
blinking.
Point
the
IR
remote
controller
to
the
IR
port
of
interface,
the
blinking
icon
will
be
moved
to
the
next
one.
Which
means
one
code
is
programmed.
Repeat
this
step
until
all
icons
are
programmed.
The
programming
of
AV2
is
the
same
as
above.
