4.1 LED Indications
4.2 Automatic GSM Signal Level Measurement
After powering up the AGM with the SIM card inside, the module performs an automatic
signal level test.
For the first 30 seconds after powering up, the Green LED will flash between 0-5 times
in cycles, (with a delay of 5 seconds between each cycle), indicating the RSSI level (0=
No network connection, 5= Very High).
If the signal level is not satisfactory or poor, consider installing the AGM in a better
signal receiving location.
