(Very) Quiet. Shhhhhhhhh

This must be the longest I have ever been allowed to have the remote in my Possession!! I wanted to photograph the mute button for missymoo's theme of 'Quiet' but I had to ask if the TV remote even had such a button. What would I know, I'm unfamiliar with such things and now I come to think about it, this button is the only one I could say for sure what it does. The rest remain a mystery!!
