An individual tone may be energized by shorting pin 6
(common ground) to the corresponding pin of the de-
sired tone. The tones will continue for as long as the clo-
sure is maintained. If background music is passed
through the
MTG-10
, it will be faded out during the tone
and then faded back in. The tone associated with pin
number 1 of each group has priority and will interrupt any
other on-going tone.
