What does this mean, and why is it on my psp?

Its on European PSPs only, i think. Got one with this sticker myself.

It says "If you listen to long with full volume, your ears may suffer severe damage"

That's why there' s also this ALVS? Option built into the XMB.

im sure it is french, i speak a little, pm video freak, i remember him saying that he was fluent in french

Ya, it says that listening to your earphones on full blast too long can damage your ears.

Indeed it can.

thanks for the reply all :)
