Tone

This sets the CTCSS tone to be transmitted if the Tone Mode is set to Tone. In Cross mode, it has additional meanings (see description of Cross Mode for more details).

ToneSql

This sets the CTCSS tone to be transmitted and used for receiver squelch if the Tone Mode is set to TSQL. In Cross mode it has additional meanings (see description of Cross Mode for more details).

Earlier, it seems, I was confusing the Tone Mode column notes with the notes under Cross mode. I think that the lines above are what I was expecting. I now see the <blank> under Cross Mode.
