The trig type uses the trigger source to switch from the
current tone to the next. The other two types, gate and
fsk (frequency shift keying) are outside the scope of this
Getting Started Manual but are covered in detail in the
Users Manual.
If there are more than three tones defined in the list you
can navigate up and down using the cursor keys. You can
enter the frequency of each tone using the numeric
keypad or the rotary control, and you always have the
option to delete the currently selected tone using the del
soft key. For the unselected tones the word del is
replaced by the numeric position in the list.
As an exercise for this Getting Started Manual you could
set the frequencies of six tones to tune a guitar.
The frequencies for conventional E, A, D, G, B, E tuning
(based on A=440 Hz) are shown in these two screens:

220.0000
293.6600
TONE
392.0000
493.8800
659.2600
You should also press the TRIG IN key and check that the
trigger source is manual.
You can now step through the 6 audio frequencies using
the MAN TRIG key and listen to them on headphones
attached to the MAIN OUT socket.
One of the important uses for the tone generation
capability of a multi-channel instrument is for DTMF (dual
tone multi-frequency) testing of telephony equipment and
systems. This use is described further in the Users
Manual.
