60D chirps twice on power-up and shutdown

[NoahRoss]

i've been using ML for a year and a half on several cameras and have never had a problem with any of them. but today when i threw ML onto a new sdhc card and booted it up something that has never happened before happened. my camera made two small chirping shounds. the same thing happened when i turned the camera off. i tried booting it with another sd card with ml on it, and the camera made the nose again.

wtf is going on with my camera?

The sounds are coming from the sensor auto cleaning function. Don't worry, this is absolutely normal!
