|When you enter this function, the tone that you created previously is shown, if available. To enter a new or edit an existing tone:|
|Enter the desired notes. For example, press
 for note f. The phone plays each note after it is entered
(unless the phone tones are off).
To adjust the characteristics of the note, do as follows:
Note duration:  shortens (-) and
 lengthens (+) the duration of the note or rest. The
default duration is 1/4. The duration is shown in front of the note, e.g.
16d denotes a note d with duration 1/16.
Rest:  inserts a rest (i.e. pause) of the same duration as the previous note. The default duration of a rest is one quarter note (1/4). The rest is indicated by the - character.
Octave: [*] sets the octave for new notes. The octave is shown as a number after the note (e.g. e1).
Pitch: [#] makes the note sharp (indicated by # in front of the note), e.g. #f. The pitch selection is not available for notes e and b.

guides look pretty similar.)
