AUTOMATIC
ENGINE
DISABLE
(AED)
ON/OFF:
AED
is
a
full-time,
passive
starter
disable
that
works
independently of the security
system.
When
turned
on,
the
orange,
ground-when-armed
output
(H
1/1)
will
go
active
30
seconds
after
the
ignition
is
turned
off.
The
LED
will
flash
at half
its
normal
rate
when
the
ignition
is
turned off
to
indicate
that
AED
is
active
and
will
interrupt
the
starter
in
30
seconds.
AED
does
not
occur
in
Valet
mode
and
can
be
bypassed
using
the
emergency
override
procedure.
The transmitter
can
also
be
used
to
disarm
AED.

ARMED
WHILE
DRIVING/VEHICLE
RECOVERY
SYSTEM:
In
the
default
setting
(Armed
While
Driving),
the
system
can
be
armed
with
the
ignition
on.
When
armed,
the
ground-when-armed
is
not
active
and
the
sensors
are
bypassed.
The
door
triggers
will
remain
active.
If
programmed
to
the
Vehicle
Recovery
System
(VRS®)
setting,
VRS®
will
be
activated.

CODE-HOPPINGTM
ON/OFF:
The
system
uses
a mathematical
formula
to
change
its
code
each
time
the
transmitter
and
receiver
communicate.
This
makes
the
group
of
bits
or
"word"
from
the
transmitter
very
long.
The
longer
the
word
is,
the
easier
it
is
to
block
its
transmission
to
the
unit.
Disabling
the
Code-Hopping™
feature
lets
the
receiver
ignore
the
Code-Hopping™
part
of
the
transmitted
word.
As
a
result,
the
unit
may
have
better
range
with
Code-
HoppingTM
off.

SIREN/HORN
HONK:
The
system
can
be
programmed
to
output
pulses
instead
of a continuous output
when
the
system
is
triggered.
This
is
useful
to
honk
the
factory
horn
in
applications
where
a
siren
is
undesirable.
Remember
that
the
unit
is
only
capable
of
supplying
1
amp
ofcurrent. A
relay
will
be
required
to
interface
with
most
factory
horn
systems.

SIREN
DURATION
30/60
SECONDS:
It
is
possible
to
.program
the
unit
to
sound
for
30
or
60
seconds
during
the
triggered
sequence.
Some
states
have
laws
regulating
how
long
a
security
system
can
sound.
When
using
the
998T
Bitwriter,
the
siren
can
be
programmed
to
sound
for
any
length
of
time
ranging
from
1
to
180
seconds.
Using
the
SELECT
button of
the
998T
Bitwriter
will
adjust
the
siren
duration
in
one
second
incre-
ments.
