•  The 1 Piece (Gen 4) has a defined call-in interval that is determined by the 
contract. If the 1 Piece (Gen 4) is unable to call 3M Electronic Monitoring at 
its defined call-in interval, a default 90 minute grace period will go into 
effect. If the default 90 minute grace period expires and the 1 Piece (Gen 4) 
has still not called 3M Electronic Monitoring, the database will create this 
alarm.  This is normally due to poor cellular coverage in the area. The 
offender is not notified of the Unable to Connect alarm. 
  
 Once the 1 Piece 
(Gen 4) is able to use the cellular network to call in, it will report any 
violations that occurred during this time and download all tracking data.
