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.
