@ Sue,
This post has taken several turns - no parts were discarded - we've bumped against, "native/non-native English."
I discovered an implementation issue w/this poster - alerted him - and issue was solved. Further - our group has run in excess of 15K "LMI/TI M3s & TI M4s" not a one arrived, "locked!" And - I relayed this finding to poster - who then dug deeper - resolved his issue!
Your devices have past arrived - and continue now - "to arrive in proper condition!"
Trust this clarifies/comforts - always my objective...
