Convenient Functions; Using The Tone Squelch; Setting The Tone Frequency - Yaesu FTM-400DR Operating Manual

This radio is equipped with the CTCSS (Continuous Tone-coded Squelch System) which
allows audio to be heard only when receiving signals containing the same frequency
tone as the tone that has been set in the tone squelch menu. By matching the tone
frequency with the partner station in advance, a quiet standby is possible.
CTCSS does not work in the digital mode. Use the
communication mode to the auto-mode select function (AMS), or to the analog mode.
The tone can be selected from 50 frequencies between 67.0 Hz and 254.1 Hz.
