Do you have lite, v3, or v4?
If you have lite, then you cannot change your sounds.
If you have v3, you have to alter the sounds using the launcher.
The v4 comes with 8 preloaded fonts (1 is mute). To change sounds with the v4, you hold down the button with the sound off for a few seconds. The saber will come one, then go off, and you will then hear the ID sounds (a.k.a. tag sounds) for the font you have selected. Pressing the button again will change the font. Holding the button down for several seconds will select the new font. You can also alter the fonts in the launcher.
