Sony KV-20VM40 - Manual (Page 22)

This table describes the relation between the sound output from the
^speaker, the recorded sound, and the MTS mode. For instance, if you set
MTS to "SAP" and a SAP signal is not being broadcast, the sound from the
speakers is muted. However, if you record the same program, the sound
will be recorded in the program's primary audio channel (stereo or mono).
