J. VALET MODE: (System in Disarm or Valet mode):
The valet switch allows you to temporarily bypass all alarm functions, eliminating the need to hand your
transmitter to parking attendants or garage mechanics. When the system is in valet mode, all alarm
functions are bypassed, however the remote panic feature and remote door locks will remain operational.
To use the valet mode, the system must first be disarmed either by using your remote transmitter, or by
operating the Manual override sequence.
Enter Valet Mode:
1. From the disarmed condition, turn the ignition to the “ON” position.
2. Push and hold the valet switch for 2 seconds until the LED turns on. The LED will remain on as long as
the system is in 'valet mode'.
Exit Valet Mode:
1. Return to normal operation, turn ignition 'on'.
2. Push and hold the valet switch for 2 seconds, LED will turn off to indicate system has exited valet mode.
Parking light flash to confirm enter valet mode and two parking lights flashing to confirm exit valet mode.
Remote Valet Mode:
1. Press and release button on transmitter three times within 3 seconds to enter or exit valet mode.
2. One parking light flash will confirm you have entered ‘valet mode’ and two parking light flashes will
confirm you exited ‘valet mode’.
K. CAR LOCATOR:
Press the button to activate car locator function. The siren will chirp 6 times. The parking light will
flash 12 times, for you to easily locate your car.
L. PANIC FUNCTION: (See Alarm Feature V –4 Programming):
The transmitter can be used as a remote panic switch to manually trigger the alarm in case emergency.
1. Press and hold the button for 3 second. The alarm will immediately sound.
2. During panic mode, the normal function of this transmitter button will be suspended. The and
buttons can be used to lock and unlock the doors (if the option is installed), however once the
button is pressed, the vehicle’s starter disable device, (where installed) will be enable allowing vehicle
to start.
3. To stop the alarm, press and hold the button on the transmitter again for 3 seconds. Also if any
transmitter button other than or or button is pressed and released, the panic mode will be
turned off immediately.
4. If the button is not pressed, the alarm will automatically stop after 30 seconds.
M. TRIGGER THE SYSTEM:
When armed, your vehicle is protected as follows:
1. Light impacts will trigger the warn-away signal.
2. Heavy impacts / Doors open / Hood open / Trunk open / Turning on the ignition key will trigger the
programmed sequence.
The starter disable relay (if installed) prevents the vehicle’s starter from cranking. The siren, horn, parking
lights, and dome light will turn on to alert of an intrusion for 30 seconds. Then it will stop and automatic
reset and re-arm. If the one of sensors or detectors is still active, the alarm system will sound a maximum
of 6 times of 30 seconds cycles.
STOP THE MELODY SOUND ONLY: While triggering the alarm the LCD screen will alert user through
melody sound and flashing trigger icon, press any button on the LCD remote transceiver to stop melody
sound only
NOISE ABATEMENT CIRCUIT: Your system has “Noise Abatement Circuit”. It prevents annoying
repetitive trigger sequences due to faulty door pin switches or environmental condition such as thunder,
jackhammers, airport noise, etc.
Here’s how “Noise Abatement Circuit” works: The alarm triggers five times. Each time the same sensor or
switch is triggering the alarm, the “Noise Abatement Circuit” will interpret this pattern of triggers or false
alarms. After the fifth trigger, “Noise Abatement Circuit” ignores, or by pass, that sensor or switch until the
other sensor or switch is trigger.
“Noise Abatement Circuit” covers doors, hood, and trunk differently: If the alarm is triggered by an open
door for six full cycles (three minutes), the doors will be bypassed until the trigger ceases.
N. ANTI CAR-JACKING:
Warning: If you do not need the carjacking function in this alarm system, be sure to set car-jacking
feature “OFF”. The default setting for this system is all car-jacking “OFF”. (See Alarm Feature I –4
Programming).
