In the table that follows, I have used the numbering convention that bit 0 is the least significant bit and bit 7 is the most significant. So a value in an SF message of '02' would be '00000010' in binary, and I would refer to that as being bit 1 set.

| *TD* | *Address* | *Bit* | *Meaning when 1* | *Updated by* | | LB | 00 | 0 | Signal L1 at danger | John Smith |
