USER MANUAL
PANDORA DXL 1840L CAR SERVICE-SECURITY SYSTEM
Anti-Hi-Jack-2 mode
This mode is disabled by default. Use Pandora AlarmStudio application to enable this mode. Anti-Hi-
Jack-2 mode helps to prevent aggressive seizure of the car using delayed engine blocking on radio tag
disappearance. The system requests a response from a tag using a unique algorithm when the ignition
is switched on. If the system cannot detect a radio tag, the engine will be stopped after 1 minute (gen-
eral safety requirement for car movement). «Engine blocking warning» ringtone will play from siren and
beeper before blocking. When warning signals end, the system will block the engine. Engine blocking
will occur immediately or when the car starts moving, it depends on block implementation and system
settings.
Code immobilizer using original car controls
Code immobilizer (validator) is a function that allows disarming, disabling blocking and controlling tim-
er channels using original car controls (button, lever or pedal). To enter immobilizer code, programmed
button (lever, pedal) should be pressed a number of times equals the first digit of the code. Pauses
between presses should not exceed 1 second. Pauses more than 1 second will be interpreted as the start
of next digit input. Immobilizer code can consist max of 4 digits from 1 to 9.
After entering a correct immobilizer code, depending on the settings, either the engine blocking will be
lifted or a programmed timer channel will be activated or the system will be disarmed.
Maintenance (Valet) mode
It is recommended to put system into maintenance mode before handing it to the car service or valet
parking. When this mode is switched on, security system stops interfering with built-in electronics and
disables all functions to ease maintenance or parking. Moreover, you will not have to leave the remote
control or radio tag to the valet or the mechanic. You can enable/disable this mode using a radio tag,
mobile phone or immobilizer button (if the ‘Code immobilizer’ function is implemented).
Enable/Disable the maintenance mode using a radio tag:
To enable/disable the maintenance mode, the radio tag should be in the coverage zone. Enter the
‘Immobilizer PIN-code’ (if the ‘Code immobilizer’ function is implemented). Press and hold the button on
the tag for 3 seconds to enable the maintenance mode.
Press and hold the button on the tag for 3 seconds again to disable the maintenance mode.
Enable/Disable the maintenance mode using a phone:
To enable the maintenance mode, disarm the system, switch on the ignition, the radio tag should
be in the coverage zone (if the immobilizer/AntiHijack function is activated), enter the ‘Immobilizer PIN-
code’ (if the ‘Code immobilizer’ function is implemented). Call the system number. Wait for answer.
• To enable maintenance mode, dial “Enable maintenance mode“ DTMF command 551*
• Enter the ‘Secret PIN-code’ that is located on the owner’s plastic card – the maintenance mode will
be activated.
• To disable maintenance mode, dial 552* DTMF command.
Enable/Disable the maintenance mode using an immobilizer button:
To enable the maintenance mode, disarm the system, switch on the ignition, the radio tag should
be in the coverage zone (if the immobilizer/AntiHijack function is activated), enter the ‘Immobilizer PIN-
code’ (if the ‘Code immobilizer’ function is implemented) and press the same button 10 times within 20
seconds after entering the PIN-code. To disable maintenance mode switch on the ignition and enter the
‘Immobilizer PIN-code’.
Replacing immobilizer tag battery:
Carefully open the cover of the tag’s battery
compartment. Extract discharged battery and
insert a new one keeping in mind the correct
polarity. Replacing a battery will not cause a
loss of tag code information, as authorization
data is stored in the non-volatile memory of
the MCU.
Carefully close the cover of the tag’s battery
compartment. All elements of construction
should be rigidly locked in places. If it is so, the
tag can be operated as usually.
