7 Troubleshooting
Note
If the LED is:
• OFF, the unit is faulty, or it does
not have sufficient input voltage,
or the connection of the connector
X2 is not ok. Proceed with step 5.
• Flashing: An internal error has oc-
curred, proceed with step 13.
Use a multimeter and insulating gloves.
The input voltage should be 24 V.
Make sure that connector X1 is connected
properly on both ends.
• If the input voltage is normal, pro-
ceed with step 6.
• If the input voltage is abnormal,

with step 9.
• If there is a problem with the con-
nection, repair the connection and
go back to step 7.
• If the antenna is not working, repair
the connection or move the an-
tenna to a location with better RF
signal.
• If the antenna is ok, proceed with
step 13.
Verify that the configuration is done cor-
rectly.
Verify that the mobile operator is detected
