Sparky did you order a SX900 also?
No,waiting for things like this issue to pop up. Just looking at the face of it you would think the button was for on/off.
Helpful to see other users experience. Anything short of downloading and reading the manual ahead of time doesn't give you the whole function picture.
And at this point, it would be an outboard vh with an sx700 or ea7 (I've read that manual)..
