hellbilly- i'll have to look at mine and then write down the steps. It was pretty easy. I know I started with menu and from there I'll have to get back to you!
Eventually you'll come to a SOUND OFF / ON button and you just select it to be OFF. that will stop it from making that dinging sound when you hit REC and when you open up the screen panel. It's completely silent now.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
