SYSTEM UNIT
.
The system unit performs the essential guarding functions thus it
is extremely important to hide it well in the vehicle's passenger
compartment. The manufacturer supplies the alarm system with a
default 4-digit PIN code, which is written on the alarm system
information sticker (see Fig. 1). The user should change it into
another, more memorable, 4-digit number. It is recommended to
write down the new PIN code, however, do not keep this
information inside the vehicle. In addition, do not use your birthday
date or home address numbers for the PIN for security.

ARMING THE SYSTEM
.
3.1.
REGULAR ARMING.
For arming, press the remote control LOCK button shortly. The vehicle direction indicators will flash and the siren will make a short
(0.1 second) confirmation sound (if this feature is set by the installer) to inform you that the system is armed. The system LED will go ON,
making constant short flashes. When the system is armed, opening the vehicle's door, bonnet or luggage compartment, vehicle's body
tilt/impact to the vehicle’s body or a movement inside the vehicle will trigger the alarm system.
3.2.
ARMING WITH SENSOR BYPASS.
3.2.1. SENSOR BYPASS WITH THE HELP OF THE OVERRIDE BUTTON.
With the ignition turned OFF press the override button. Watch the system's LED, its flash will mean that the press has been confirmed.
Get out the car, close the doors and lock the Central Lock with the remote's LOCK button within 20 seconds. The siren will make a long
(0.5 second) confirmation sound (if this feature is set by installer) to inform you that the system is armed with a bypassed ultrasonic and/or
tilt/shock sensor(s) and the movement inside the car and/or car's body tilt/impact to car's body will not trigger the alarm.
3.2.2. SENSOR BYPASS WITH THE HELP OF THE IGNITION KEY.
Turn the ignition ON and OFF three times. Watch the system LED, its flash will mean that the third ON/OFF procedure is confirmed.
Get out the car, close the doors and lock the Central Lock with the remote's LOCK button within 20 seconds. The siren will make a long
(0.5 second) confirmation sound (if this feature is set by installer) to inform you that the system is armed with a bypassed ultrasonic and/or
tilt/shock sensor(s) and that movement inside the car and/or car's body tilt/impact to car's body will not trigger the alarm.
3.2.3. SENSOR BYPASS
WITH THE HELP OF THE OVERRIDE BUTTON WHEN THE IMMOBILIZER IS ACTIVE
.
When the inner immobilizer feature of the car alarm system is turned ON and the engine is immobilized, the system's LED will emit
long flashes. First press of the override button which will turn the immobilization OFF. The next press of the override button will start the
bypassing procedure as described in chapter 3.2.1
.
3.3.
ALARM INTERRUPTION
.
The system will trigger the alarm if the vehicle's doors, bonnet or luggage compartment are opened, the ignition is turned ON or the
ultrasonic sensor is triggered. To interrupt the alarming of the system disarm and re-arm it.
4.
DISARMING THE SYSTEM
.
Press the remote control UNLOCK button once shortly. The vehicle direction indicators will flash and the siren (if it was set by installer)
will make two short (0.1 second) confirmation sounds to inform you that the system is disarmed. The system's LED will turn OFF.
5.
THE OVERRIDE MODE
.
Alarm system override mode is used for cases such as the loss of the remote control unit, the remote's battery becoming completely
discharged or in the case of the car being repaired. With this mode ON, the alarm system does not respond to the sensor(s), does not
immobilize the engine and does not alarm (N.B. the system's LED flashes frequently). The override mode can be turned ON in two ways
with the PIN code.
5.1.
TURNING ON THE OVERRIDE MODE WITH THE HELP OF THE OVERRIDE BUTTON.
The most convenient way to turn ON the override mode is to enter the PIN code with the override button. If the override button is
installed, check your notes with the alarm system's PIN on, press the override button as many times as the value of the first digit of the PIN
(the time between the presses should not exceed 1 second) and wait for a 1 second lasting LED flash, which will mean that the first digit is
entered successfully. In the same way enter the second, third and fourth digits of the PIN. If the 'anti-carjack' or immobilizer features are
activated, the system will respond to the first press of the override button as to the control of the 'anti-carjack' or the immobilizer functions.
To the next presses of the override button the system will respond as if the PIN code is being entered.
5.2.
TURNING ON THE OVERRIDE MODE WITH THE IGNITION KEY.
If the override button is not installed, open the vehicle's door and turn the ignition ON. Shortly after the system LED starts flashing
double flashes, count until the number of double flashes (1 double flash = 1 unit) corresponds with the first digit of the PIN code. Turn the
ignition OFF for a short time and turn it ON again. Count the double flashes until the number corresponds with the second digit of the PIN
code. Turn the ignition key OFF and ON again. Enter the remaining two digits of the PIN code in the same way. Upon correct entry of all
four digits of the PIN code the LED emits frequent flashes. If you make a mistake while entering the PIN code, turn OFF the ignition, close
the doors, and follow 5.2 all over again.
5.3.
TURNING OFF (EXIT) THE OVERRIDE MODE.
Enter the PIN code and enter the code '11' in a way as described in 5.1 or 5.2 within 8 minutes of the previous step.
5.4.
CHANGING THE PIN CODE
.
The user has a possibility to change the PIN code. In order to do that, do the following steps:
a)
enter the current PIN code, the system's LED will emit single flashes frequently;
b)
in the same way as the PIN was entered before, enter the code '88'. The entry will be confirmed by a short flash of direction indicators;
c)
within 8 minutes of the previous step enter the new PIN twice, one after another. In a case the same code was entered twice, the system
will record this as the new PIN code and confirm it by a short siren sound;
