PANDORA DXL 1920L/1930L CAR SERVICE-SECURITY SYSTEM
You can also check the number of recorded tags and registered mobile device by taking off and
putting back on battery terminal. The system will emit short sound signals from a siren with less than
1 sec. interval. The number of the signals equals to the number of recorded tags. After a pause of 2
seconds the system signal will indicate registered mobile device.
CONTROL OVER THE SYSTEM
Arming/disarming using radio tag
To arm/disarm the system, RF tag should be in radio coverage area.
The system produces a protected (AES-128 encryption) interactive
high-speed exchange of authorization codes in the frequency
range 2,4 GHz on one of 125 channels. To arm the system when the
ignition is switched off, shortly press the tag button. The system
will confirm the command receiving with 1 short sound signal and
1 flash of turn indicators. To disarm the system, shortly press the
tag button. The system will confirm the command receiving with
2 short sound signals and 2 flashes of turn indicators. Each button
press will be confirmed with LED indicator flash of the tag that
indicates the battery is functioning correctly. If LED indicator does
not flash or constantly lights, the tag battery should be replaced
(see “Replacing immobilizer tag battery“ section).
Arming/disarming in Hands Free mode
The system allows for programmable Hands Free arming and disarming. To arm the system, when the
engine is not running, move with the remote tag away from the car at a distance greater than the
regular radio coverage (10 meters for 2,4 GHz) – the system will be armed automatically. To disarm the
system, move toward the car with remote tag. Enabling/disabling this function can be performed with
a phone (see “Control over system via a phone“ section).
Arming/disarming in «Slave» mode
In this mode it is possible to monitor the status of original security system of the car via CAN-bus or
by analog inputs. When arming and disarming original security system, Pandora will be armed and
disarmed respectively. The presence of a tag in the radio zone is not required, but at the beginning of
motion if the tag is not detected by the system, the engine will be blocked.

USER MANUAL
PANDORA DXL 1920L/1930L CAR SERVICE-SECURITY SYSTEM
There is an option in the system settings named “Prohibit disarming when the tag is absent“. When
this option is enabled, disarming procedure will be performed only if there is a tag in the radio zone.
Immobilizer mode
This mode is enabled by default. Use a phone to disable this mode (see “Control over system via a
phone“ section). When switching on the ignition, the base unit of Pandora security system performs a
search for immobilizer tags in radio zone. If no radio tags were detected when the ignition is switched
on, the system will block the engine with all radio relays that were programmed into the system. Engine
blocking will only occur when motion sensor detects movement of the car. If additional analogue
blocking relays were installed, they will block the engine immediately, before or when the car starts
moving, it depends on system settings.
Anti-Hi-Jack mode
This mode is disabled by default. Use a phone to enable this mode (see “Change settings via a phone“
section). Anti-hi-jack mode helps to prevent aggressive seizure of the car using delayed engine blocking
on door opening.
Every time on opening/closing a door when the ignition is switched on, immobilizer requests response
from a radio tag using unique algorithm. After a door was opened while the engine is running, if the
system cannot detect a radio tag, the engine will be stopped after 1 minute (general safety requirement).
A siren will play “ENGINE BLOCKING WARNING“ ringtone before blocking.
If engine blocking is performed via radio relay after warning signals are over or on new attempts
to start the engine, immobilizer will only allow the engine to start when the car is not moving, and will
block it again if it starts movement.
If the car starts moving, the immobilizer will block the engine for 15 seconds. When registered tag
appears in the radio zone, blocking will be canceled and the system will return to the normal operation.
If the engine is blocked via analog relay, engine operation will be stopped after warning signals are
over, until a registered tag appears in the radio zone or on registering movement – depending on the
settings.
Code immobilizer using original car controls
Code immobilizer (validator) is a function that allows disarming, disabling blocking and controlling timer
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 to the 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.
Replacing immobilizer tag battery
Carefully open the cover of the tag’s batter y
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 batter y
compartment. All elements of construction should
be rigidly locked in places. If it is so, the tag can be
operated as usually.
Control over the system in case of emergency
Use a phone to deactivate the system quickly. To disarm the system via a phone, call the system’s
number. When it answers, dial command 0*. If the call is not made from the owner’s number, guest PINcode should be entered. Factory set guest PIN-code is 1-2-3-4.
To switch off an immobilizer tag, dial the 998* command (after dialing, enter the “Secret PIN-code“
that is located on the owner’s plastic card). To switch on an immobilizer tag, dial the 888* command.
If the system cannot be deactivated via a phone, apply emergency disarming and switching on/off
an immobilizer tag using VALET button.
