1.3.3 LED Indicators
When AVL is in work mode, if GSM signal is in good state, the green led
will flash, similarly, if GPS signal is in good state, the blue led will flash, if
the green led is not flashing, that indicates the GSM signal is not good, if
the blue led is not flashing, then you should check if there is something
upon the GPS antenna top. Further, if you find the three leds are dark,
maybe the AVL entered into "sleep-mode" or there is no power in the AVL
unit.

2. How to use the Product
2.1 prophase to prepare
Step1: Inset a SIM card.
make sure the SIM card can communicate with other cards via SMS
and call, and before installing the SIM card to the holder, please use a
mobile phone to empty the SMS storage of the card
Step2: Connect GSM Antenna and GPS Antenna to AVL unit.
(GPS antenna)

(GSM antenna)
When you connect to the GSM and GPS antenna,pls make sure that it is
until the connection is very firm.
Step 3: Fix the AVL connect the to the exterior power by 12V.
Pls refer to the introduce about I/O ports,port7 and port 8 apart connect
to the exterior power of anode and cathode.
Step 4: Turn on the AVL, observe the three leds in the AVL.
Turn on the AVL, you will see the three leds flash at the same time.
It entered into initial mode.
After about 1 mins ,the device will work normal,then you could
look the leds of status and refer to the introduce about 1.3.3 led
indicators.
When AVL is in work mode, if GSM signal is in good state, the
green led will flash, similarly, if GPS signal is in good state, the blue led
will flash, if the green led is not flashing, that indicates the GSM signal is
not good, if the blue led is not flashing, then you should check if there is
something upon the GPS antenna top. Further, if you find the three leds

are dark, maybe the AVL entered into "sleep-mode" or there is no power
in the AVL unit.
Notes: As everyone knows,the GPS signal is very weakly or have no
GPS signal in the office .So pls put the AVL02 to the open air in order to
receive the great GPS signal.
