Stand 2014.12:
After switching the slide switch on the side of the camera remains in the receiving mode.
Even if you push back the switch, this is not changed.
As I learned from the responses, this is only the case with me. Monday model.
Supplement 2015.02:
After many attempts - had last 2 cameras and 3 UW-housing - has been found that the camera that I have previously bought half a year and not the UW-housing is defective. The camera does not support the switch from UW-housing. Now have a new camera (uncomplicated handling thanks to Amazon) and everything works very well. Now 5 Stars.
