Both phones: You should then be shown a musical score, if there are any musical notes in it press and hold the top left menu button the clear them ready for your new ringtone.

2.  Enter the key press sequence

Once you have located the composer on your phone,  you need to enter the key press sequence given to you by the ring tone converter software.  

Now (in the phones melody composer),  simply type these numbers into your keypad.

Numbers in brackets indicate the number of times you need to press the preceding key. As you press the key again and again musical notes will appear, then move down the screen. For example 3(4x) means press the '3' key four times, or 3(5x) means press the '3' key five times.

Where you see 'v' press the middle scroll button down once, this will move you onto the next note.

3. Save the tone

Finally press the top right menu button to play the ringtone and store it on your phone if you like it!

After you have stored the tone you can alter the speed it plays at using the 'Timebeat' option on your phone,  this is in the same menu as the play option on both the T191 and C300 hansets.

If the tone doesn't sound right,  you have probably missed a key so you may wish to try entering the key sequence again.

That's it - it could not be simpler,  or cheaper to add a new ring tone to your Motorola C300 or T191 phone (as often as you like!)
