Important Information
By carefully reading this guide prior to using your system, you will
maximize the use of this system and its features. This system has
been designed to provide years of trouble-free operation. Due to its
complexity, it must be installed by an authorized dealer only. In-
stallation of this product by anyone other than an authorized dealer
voids the warranty. All dealers are provided with preprinted dealer
certificates to verify that they are authorized.
This system does not require any specific maintenance. Each remote
is powered by a miniature 3-volt battery, type 2032, that lasts ap-
proximately one year under normal use. When the battery weakens,
the LED on the remote will dim and flash quickly whenever it is used.
System Maintenance

Your warranty card must be returned and the barcode serial number
must not be removed. If the warranty card is not returned, you do
not have a warranty. It is also necessary to keep your proof of pur-
chase, which reflects that the product was installed by an authorized
dealer. Make sure you receive the warranty card from your dealer.
This device complies with part 15 of FCC rules. Operation is subject
to the following two conditions: (1) This device may not cause harm-
ful interference, and (2) This device must accept any interference
received, including interference that may cause undesired operation.

figuration, but may also be customized by an authorized dealer. Unless
otherwise specified, all instructions in this manual assume opera-
tion using the Standard Configuration.

The auxiliary output controls _____________________________.
Using Your System
The buttons described in all instructions in this manual correspond
to the standard configuration, unless otherwise specified.
You can arm the security system and lock your vehicle’s doors (if
connected) by pressing for one second. When the system arms,
you will hear a short siren sound (chirp) and the parking lights will
flash once. Once armed, the status LED will flash twice per second
to indicate that the system is actively protecting your vehicle. If
you hear a second chirp after arming and notice that the status LED
is flashing in a grouped pattern, this signals Bypass Notification,
which is described in the Diagnostics section of this manual.
The system can also be programmed to arm itself automatically 30
seconds after the ignition is turned off and the last vehicle door has
been closed (called Passive Arming). Once the 30-second countdown
period initiates, the status LED will flash twice as fast as it does
when the system is armed. After 20 seconds, the siren will chirp once
