WARNING!
IT IS STRONGLY ADVISED TO HAVE PROFESSIONAL CAR MECHANIC INSTALLING THE
SYSTEM. CERTIFIED INSTALLERS ARE RARE OUTSIDE RUSSIA, BUT ANY CAR ELEC
TRONICS INSTALLER SHOULD BE ABLE TO INSTALL PANDORA DXL1820L/1830L
USING INSTALLATION SCHEME IN THIS MANUAL AND ALARMSTUDIO SOFTWARE.
MOST FEATURES ARE HIGHLY DEPENDENT ON COMPETENT INSTALLATION.
OUR SYSTEMS ARE THOROUGHLY TESTED FOR QUALITY, SO IF A FEATURE FAILS
TO PRODUCE EXPECTED RESULTS, MOST LIKELY THE PROBLEM IS IN IMPROPER
INSTALLATION.
It is essential for systems functioning that you read and understand instructions in this manual.
Note that all radio devices are subject to interference, which could affect proper performance.
This device has limited external factors resistance. It should not be subjected to water beyond occasional splatter, or operated in
temperatures outside -40 to +80 oC range.
IMPORTANT! Note that this manual describes remote and manual functions for the
most part. Functionality of the system is vast and would require a book-sized manual to
fully describe. Instead we use a handy software named AlarmStudio that functions as both
programming tool and an extended installation & functionality manual. It requires Windows
and can be downloaded at pandorainfo.com

CONTROL OVER SYSTEM
Arming/disarming using radio tag button
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 light, 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 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.
There is an option in the system settings named ‘Disable disarming when the tag is not present’.
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
phone’ section). When engine is running, base unit of Pandora security system performs a search
for immobilizer tags in radio zone. If no tags were detected, LCD remote will play ‘NO TAG FOUND’
ringtone. 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.
Antihijack mode
This mode is disabled by default, use a phone to enable this mode (see ‘Change settings via
phone’ section). Antihijack mode helps to prevent aggressive seizure of the car using delayed engine
blocking on door opening.
Every time when the engine is running on opening/closing a door, immobilizer requests response
from a remote 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). ‘ENGINE BLOCKING WARNING’ ringtone will play 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. Immobilizer will be in active mode in no more than 2 seconds
after the ignition is switched on. 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.
WARNING!
ANTIHIJACK MODE IS NOT LEGAL IN SOME COUNTRIES.
Immobilizer code using original car controls
Code immobilizer 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 equal the 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 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.
Control over 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
PIN-code should be entered. Factory set guest PIN-code is 1-2-3-4. To switch off immobilizer RF tag/
Antihijack mode, dial command 998* (after dialing, enter individual PIN-code that is located on the
owner’s plastic card).
If the system cannot be deactivated via a phone, apply emergency disarming/switching off
immobilizer RF tag using VALET button.
Emergency disarming/switching o immobilizer using VALET button
In case you cannot disarm the system using a remote, owner’s individual PIN-code can be used.

the button a number of times, equal to the first digit; pauses
between presses should not exceed 1 second). The system will
confirm with red LED indicator flash.
2. Similarly input the second, third and fourth digit. Every input will be confirmed with red LED
flash.
3. The system will confirm correct PIN-code with red and green flashes of LED indicator. If the input
was incorrect, it will be indicated with long red flash. New input can be attempted after 5 seconds.
If immobilizer/Antihijack mode is activated:
4. Using VALET button, input PIN-code. Factory preset PIN-code is 1-1-1-1 (4 presses with pauses
for 2 seconds).
5. The system will confirm correct PIN-code with red and green flashes of LED indicator and will
enter programming mode. New input can be attempted after 5 seconds.
6. To switch off immobilizer/Antihijack function, press VALET service button 15 times (pauses
between presses should not exceed 1 second). The LED will be lit green.
7. Input individual PIN-code similar to emergency disarm. The system will confirm correct PINcode with 2 short signals of the siren and with red flash of LED.
8. To activate immobilizer/Antihijack function, enter level 15, the system will confirm it with red
