This system is for vehicles with 12V DC only.

System should be installed by a professional 
auto technician.

The installation position of ECU should be 
kept away from water and dust.

All components should be fixed tightly and 
the wires must be long enough to avoid 
disconnection from heavy vibration during 
driving.

This system will help to reduce the possibility 
of losing the vehicle by discouraging theft. 
Please take out the valuables when leaving 
the vehicle.

When the transmitter operating distance is 
shorter or its indicator light turns dark, please 
recharge the transmitter battery ASAP.

It is highly recommended to read this manual 
before using this system.

Perform a functional test after installation.

The operation distance may affected by 
constructions, topography or weather.

Please do not open or change the PCB 
without authorization.

13. Dome light delay

The function is specially designed for the 
vehicle with dome light function. The system 
will enter the arming mode automatically once 
the dome light turned OFF.

14.  Arm reminder/Passive arming

When the engine OFF and system not arm in 5 
seconds, the turn signal will flash 3 times and 
siren will trip 3 times to remind the user arming 
the system, the sound can be ON/OFF by 
Jumper 3(Default is ON);

after 1 minute, but the doors will not locked, the 
passive arming function can be ON/OFF by: 
Open door, press search button 5 s, siren will

beep 3 times, then press mute button, siren 
sound 1 time, mean auto arming ON, siren 
sound 2 times, means auto arming OFF, 10s
