70D menu settings don't persist
I just bought a 70D. I've gone through the menu many times and turned "Beep" to "Disable" and "Image jump w/wheel" to "1". If I exit the menu and then immediately re-open the menu, those settings will be as I set them. However if I exit the menu and then wait a while, or turn the camera on/off, the settings will be reset back to their default values.
Am I missing a step on how to make my settings persist across sessions? Or is something wrong with my new camera?
