Andy The source for the note is probably the FCC grant for the device.
After a quick look on the FCC's search page at https://fjallfoss.fcc.gov/oetcf/eas/reports/GenericSearch.cfm <https://fjallfoss.fcc.gov/oetcf/eas/reports/GenericSearch.cfm> I am guessing that the module you are looking at is from Multi-Tech Systems, FCC ID AU792U07G30822. I think others have replied with explanations as to the reasoning behind the requirement.
