Multiple MR10 Systems

Each separate MR10 system should use the same Group 

and Security Code for all packs in that system. CrewPlex 

recommends that systems operating in proximity to one 

another set their Groups to be at least ten (10) values apart. 

For example, if one system is using Group 03, another system 

nearby should use Group 13.
