Transmitter Functions
This system is programmable, making it possible to assign any trans-
mitter button to any specific receiver function. The remote initially
comes programmed with Standard Configuration, but may also be
customized by an authorized dealer. The buttons in all of the instruc-
tions in this manual correspond to a Standard Configuration remote.
Button
Locking/arming and Panic Mode activation are controlled by this
button. Pressing it for one second will lock/arm the system, while
pressing it for 1.5 seconds will activate Panic Mode.
Button
Unlocking/disarming, Panic Mode deactivation and an optional
auxiliary function are controlled by this button. Pressing it for one
second will unlock the doors and disarm the starter kill. This but-
ton is also used to stop Panic Mode at any time. Additionally, an
optional auxiliary function is controlled by pressing and holding it
for 1.5 seconds.
This auxiliary output controls ____________________________.

Using Your System
Pressing for one second will lock the doors and activate the
Failsafe®Starter Kill. The red LED will begin flashing once per sec-
ond and the parking lights will flash once. Pressing again
within 10 seconds of locking/arming the system will not lock the
doors again, but it will flash the parking lights and honk the horn
once, confirming that the system is locked/armed. After 10 sec-
onds, the system can be locked/armed again, as usual.
Locking/arming your system protects your vehicle in the fol-
lowing ways:
■The vehicle doors will lock.
■Turning on the ignition will initiate the Panic Mode. The Failsafe®
Starter Kill will also prevent the vehicle’s starter from cranking.
NOTE: You must use your transmitter to lock the vehicle in order for the
starter kill to be armed. Manually locking the vehicle does not arm the
system; it will only lock the doors. If you have not used the transmitter
to lock the vehicle doors (i.e. the vehicle has been locked using the
lock/unlock switch) the transmitter cannot be used to unlock the doors.
To unlock the driver’s door (or all vehicles doors, depending on if
your vehicle has driver’s door unlock) and disarm the Failsafe®
Starter Kill, press for one second. The parking lights will flash
twice and the red LED will go out. If pressing the first time

did not unlock all vehicle doors, press again within 10 sec-
onds to unlock the remaining passenger doors and the parking
lights will flash twice. Pressing a third time within 10 seconds
will flash the parking lights and honk the horn twice, confirming
that the doors are unlocked and the starter kill is disarmed. After
10 seconds, the system can be unlocked/disarmed again, as usual.
NOTE: If the system has been locked/armed with the remote, you must
use the remote to unlock/disarm the system. Manually unlocking the
vehicle does not disarm the starter kill; it will only unlock the doors.
If your remote transmitter is lost or damaged, you can manually
disarm your the Failsafe Starter Kill. To disarm the starter kill with-
out a transmitter, you must have the vehicle's ignition key and
know where the Valet switch is located. Be sure to check with your
installer at the time of installation for the location of the Valet
switch.
To disarm the starter kill, turn
the ignition key on and press
the Valet switch within 15 sec-
onds. The starter kill should
now disarm. If it does not dis-
arm, you may have waited too
long; turn the ignition off and
repeat the process.

Disarming the Starter Kill Without a Transmitter

If you are threatened in or near your vehicle, you can attract
attention by triggering the system with your remote! Just press
and hold for 1.5 seconds, and you will enter Panic Mode. The
horn will honk and the parking lights will flash for 30 seconds. To
stop Panic Mode at any time, press on the remote.
NOTE: In order for Panic Mode to function, the vehicle’s horn (or option-
al siren) as well as the vehicle's parking lights must be connected.
Code Hopping™
The receiver and transmitter use mathematical formulas called
algorithms to change their codes each time the transmitter is used.
This Code Hopping technology has been developed to increase the
security of the unit. By following this set code sequence, the
receiver and transmitter stay synchronized, even if the transmitter
is used out of range of the vehicle. If, however, the transmitter is
pressed many times out of range, or the battery is removed, the
transmitter may get temporarily out of sync and fail to operate the
system. To resynchronize the transmitter, simply press several
times within range of the vehicle. The system will automatically
resynchronize and the transmitter will respond normally.
Panic Mode

High Frequency
Your system transmits and receives at 434 MHz. This provides a
cleaner spectrum with less interference and a more stable signal.
Enjoy a phenomenal increase in range, even in areas with high
radio interference.
Programming Options
Programming options control what your system does during nor-
mal operation, and require few or no additional parts. However,
some options may require additional installation labor. The fol-
lowing is a list of the program settings, with the factory settings
in bold:
■Ignition-controlled door locks can be turned on or off. When
turned on, the doors will lock three seconds after the igni-
tion is turned on and unlock when the ignition is turned off.
■There is a ignition-controlled panic sequence that can be pro-
grammed on or off. If this feature is programmed on, Panic
Mode will initiate and the starter kill will arm whenever the
ignition is turned on while the system is locked/armed.

Security & Convenience
Expansions
Here we have listed only some of the many expansion options
available. Please consult your dealer for a complete explanation of
all the options available to you.
Domelight Supervision: If installed, the domelight will illuminate
for 30 seconds each time the system is unlocked/disarmed using
the transmitter. This is useful for seeing inside the vehicle at night
prior to entering it.
Valet®Start System: For the ultimate in convenience, the Valet®
Start System can start your vehicle, monitor engine functions, and
power your climate control system with a push of a button! Over-
rev protection, open-hood lockout, brake-pedal shutoff, and auto-
matic timer shutoff are all included. (Only for fuel-injected, auto-
matic-transmission vehicles.)
Power Window Control: Power window control is provided with
the 529T or 530T systems. The 529T system will roll up two win-
dows automatically when the system is locked/armed, or roll two
windows down. The 530T can roll two windows both up and down.
The 530T also provides one touch switch operation.
Power Trunk Release: This expansion option allows you to oper-
ate a factory power release for the vehicle's trunk or hatch. If the
factory release is not power-activated, DEI's 522T trunk-release
solenoid can often be added.

Glossary of Terms
Control Unit: The “brain” of your system. Usually hidden under-
neath the dash area of the vehicle. It houses the microprocessor
which monitors your vehicle and controls all of the system func-
tions.
Failsafe®Starter Kill: Located on-board the control module, this
is an automatic switch controlled by the system which prevents
the vehicle’s starter from cranking whenever the system is armed.
The vehicle is never prevented from cranking when the system is
disarmed or if the starter kill switch fails.
LED: Red light mounted somewhere in the vehicle. It is used to
indicate the status of your system. It is also used to report trig-
gers and faults in the system or sensors.
Transmitter: Hand-held, remote control which operates the vari-
ous functions of your system.
Valet®Switch: A small push button switch mounted somewhere
inside the vehicle that is used by the installer for programming the
system. It can also be used to override the starter kill and other
expansion options that have been added to your system. Consult
your dealer for details.
