5. Communication verification is critical for proper functionality 

of device. First verify that the device has been acquired and has 

registered to the wireless network. This may be verified in one of   

two ways. 

1.  First, installers may look at the communication LED (i.e., the 

one closest to the SMC antenna connector). 

2.  If this LED is solid, then the device has registered to the 

network and established a data session. If no connection 
please contact MiFleet support at 1.866.643.5338 opt 2.
