Maintenance
1. Please often check if the SIM card has the enough money, otherwise the main unit
can not alarm if in short of money in it.
2.
The battery of emergency panic switch should be inspected periodically and
replaced when necessary to make sure enough electricity, otherwise the emergency
panic switch can not alarm.
3.
Fix the antenna of main unit firmly and put it on the area with good capability of
receiving signal, otherwise, no signal or poor contact of antenna will make the
system unable to alarm.
4.
Keep the password secret. If other people knows it, please modify it immediately in
case others enter the system illegally.
5.
It is dangerous to use remote power/gas supply cut function. The user is suggested to
enter the call state and threaten driver to stop, give sometime for driver to stop the
vehicle, and know about the car status through monitor function and make sure
there is no danger, then use
“

”
function.
6.
In arm mode, the car key can not open the door, the ignition key can not start the
engine, the system will sound alarm. If arm by mobile or phone, user must disarm it by
mobile or phone. We suggest that user arm the system by remoter in normal
condition. If lost remoter, you can arm the system by phone to avoid other person
use the lost remoter.

position, and check SIM card if in
good contact, then turn the power switch to

Notice for Usage
1. Fix the GPS joint and make sure its bottom and surface for fear of influence on satellite signal.
2. Never use easily guessed password, such as 123456, 88888, etc.
3. When parking your car in a strange place, please check the alarm system or your
mobile phone to ensure that the parking lot is covered by GSM signal. Change the
parking lot otherwise.

When receiving the signal from the car, user can figure out that there is alarm
condition even if he/she can
’
t hear the sound.

GSM communication service could be stopped, thus causing the alarming system to
loose its functions.
