When the SIM PIN is okay: led is active
If no SIM can be detected or the SIM PIN is wrong:
blinking once
per second (slow flashing)
This LED also signs the RSSI signal strength: X number of flashing
during 10-15 seconds, repeated (RSSI value, where X value can be:
1,2,3 or 4)
The number of RSSI flashing can be:
o
RSSI <= -98
1
flashing
o
RSSI > -98 and <= -83
2
flashing
o
RSSI > -83 and <= -68
3
flashing
o
RSSI > -68
4
