First thing I notice about your camera ---
dial on the top -- LEFT --- there is a WHITE S - CL - CH
Your's is set to CL -- that's continuous LOW
S is for SINGLE
CH - is for continuous HIGH
Push down the little black button right by the dial to change it....
The lower bezel rotates -- separately from the top knurled dial.
Mess with it and you figure it out.
Ken Rockwell will tell you EXACTLY how to set up your camera.
