then press button A to arm the system (for 4-button transmitter) or press and hold button C for 3 seconds ( for 
3-button transmitter). 

6. AUTOMATIC RE-ARM     

If the system is disarmed via transmitter and any doors are not opened within 

approximately 25 seconds, the system will automatically re-arm itself. This feature guards against disarming 
caused by accidental or unintended operation of the remote transmitter. 

7. AUTOMATIC ARMING ALERT    .

5 seconds after you turn off the ignition switch and exit the vehicle ( door 

is opened then closed), if you forget to arm the system, the siren will chirp twice to get your attention so you 
should arm the system. If you still fail to arm the system, then the vehicle is not in the alarm system protection. So 
please remember to arm the system while you are away from the vehicle, or please pre-set the AUTOMATIC 
ARM function. (see below the programmable features) 

8. AUTOMATIC CENTRAL DOORS LOCK/UNLOCK     

When arming or disarming the system, the doors 

will lock or unlocked automatically. When driving the vehicle, pressing button A or button B will lock or unlock 
doors without activating the alarm system. 

9. VEHICLE LOCATING     

If you want to find your vehicle position in a big crowded parking lot, simply 

press transmitter button C (whether your alarm system is activated or not), then you will hear the siren sound 
intermittently for 15 seconds ( in mute alarm the siren will not sound) and lights will flash simultaneously for 15 
seconds to indicate the vehicle position. You can stop sound and flash by pressing button C again. 

10. EMERGENCY CALL     

If you are threatened or in any danger when you are driving (namely: the ignition 

switch is ON ), you can attract attention and scare the threatening object off by pressing transmitter button C, the 
system will respond with siren sound and headlight flashing for 15 seconds. You can stop the sound and flashing 
by pressing button C again. 

11. REMOTE TRUNK RELEASE     

Pressing and holding the transmitter button B for 3 seconds in disarmed 

mode will be unlock and open the trunk automatically. 

12. POWER DISCONNECTING MEMORY     

This alarm has built in memory on the main unit. Generally, 

after alarm power is cut and reconnected, the main unit will read back the data make the alarm resume. When in 
arm /disarm mode or anti-hijack position, power is off and on again, the alarm will read back the original position. 

13. EMERGENCY OVERRIDE (DISARM SYSTEM MANUALLY)  

If your transmitter is lost or not 

working while your system is armed, you can manually disarm your system by two methods: 
1)

 

Open the door (this triggers the alarm system) and turn the ignition switch to ON position with your key, push 
the RESET SWITCH (a red switch on the main unit) and release it (the alarm power will turn off and on 
again). Now the system is disarmed.   

2)

 

Open the door with key (this triggers the alarm system), step on the foot brake and turn the ignition switch 
quickly from OFF to ON and back for 10.5 cycles ( OFF-ON-OFF-ON, this is two cycles), stop at OFF (must 
finish these cycles within 10 seconds), the system will respond lights on, and “du….du..” two sounds. The 
system will be disarmed in 3 seconds.. 

14. ANTI- HIJACK FUNCTION (IMMOBILIZING ENGINE)   

If you are threatened when you are driving, 

you can enter anti-hijack mode with your remote control or a secret manual operation to immobilize the engine so 
that your car is disabled and not able to be stolen.   
1) Remote Anti-hijack: For 3-button transmitter: press button C (respond with headlight flashing and siren 
sounding) then button A (respond with lights flashing rapidly), indicating entering standby anti-hijack mode. If 
you press button A again within 5 seconds, then anti-hijack is executed, lights flash rapidly, siren sounds, 40 
seconds afterwards, the engine will be immobilized. For 4-button transmitter, press button D (respond with lights 
flashing and siren sounding), indicates entering standby anti-hijack mode. If now press button A, then it enters 
anti-hijack mode, lights flashing rapidly, siren sounding, engine will be immobilized in 40 seconds. To exit 
anti-hijack mode during standby anti-hijack mode or anti-hijack mode, simply press button B. 

 

2) Manual Anti-hijack with Anti-robbery Switch: There is a green button on the main unit of the car alarm, in
