the siren will chirp twice.

Emergency Override

: If you lose your

remote or it becomes inoperable, and
system is armed:

1.

Open door and enter vehicle (Siren

will sound, lights will flash).

2.

Turn ignition key to on.

3.

Press the override switch.

4.

System will disarm, and automatically

enter Valet mode, regardless of whether
system is programmed to passively or
actively arm.

Code Learning Mode

: If you wish to

“teach” the system different remote con-
trols:

1.

Make sure system is disarmed or in

valet mode,

2.

Turn ignition switch on 3 times within

5 seconds and leave in the on position
(ON, OFF, ON , OFF, and ON), you will
hear one chirp from the siren, LED will
flash one time,

3.

Within 5 seconds press and hold

valet/override switch for approximately 5
seconds, you will hear a series of chirps
and LED will turn on solid,

4.

Release the valet switch, and within 5

seconds you must press button 1 of all
transmitters that you desire to operate
the system.You will hear a chirp after the
system has learned each remote control.
The system will hold 3 different codes in
memory.

NOTE:

Once you enter the code learn-

ing mode, the system will throw out any
previous programmed remotes. If you are

programming two remotes with the same
code, the system will acknowledge only
the first remote. Even though both
remotes will operate the system.

INSTALLATION
INSTRUCTIONS:

1. Mount the module and pro-
gram dip switch functions
(see page 3):

Look for a suitable mounting location
under the dash or inside the vehicle that
will be difficult for a potential thief to
locate the module, but allow for a conve-
nient installation position.
Keep the antenna wire away from wire
looms, computer modules and metallic
objects for better range.Wire tie or
screw the module securely.

2. Mount the Siren:

Locate a suitable place under the hood,
away from hot and moving engine parts
such as manifolds, turbo chargers, fan
belts, etc. Secure siren by screwing brack-
et to a solid location under the hood.
Make sure that there is no outside access
to both siren and wire from underneath
the vehicle or through the grill.
Point the siren down so that water may
not accumulate inside the siren bell.
Ground the black wire of the siren to a
solid ground; preferably, use a star washer
and ring terminal.
