SONY instructions on how to input ringtone:

Instruction

To compose a melody you must enter the notes and pauses by pressing the number keys and the star key * until you get the desired note.

To example: 33***** = the key 3 two times and the key * five times.
Sometimes you'll find a (JD). Then you must press the JogDial.
In the upper part of the display, you can see a small piano keyboard

Just to the right of this keyboard the letter 'P' stands for pause. The duration is represented grafically with the musical symbol and the values are
1/16, 1/8, 1/4, 1/2, 1/1. (see on table #1)
During the key-pressing, looking at the display you should see the notes and pauses changing.
Through press a number key you activate the note (see on table #3) and through press the * key you can determine the length of the note (see on table #2).
If you keep a higher or lower octave, you must press the number of keys, e.g. 2x the key 1 = 11 you receive a high octave (H=High octave) and for a low octave you must press the key three times, e.g. 3x the key 1 = 111 (L=Low octave).

Attention!! When the code beginns with the key 1, you must watch out, then the cursor already stand on note C, if you start the ringtone-editor. You must put the first number 1 away. To expample, the code beginns with 111***, then you kill the first number and you must start with code 11***.
