I am not able to get the self timer function to work and I'm hoping it's operator error. I set the timer for a 10 second delay, and I set it to take 5 pictures. Then I hit the menu button twice to get back to the screen to take the picture. When I press the shutter button, I'm supposed to hear beeps and then the camera is supposed to start taking pictures after 10 seconds, but nothing happens. The lens turns as if to focus and that's all that happens. Am I doing something wrong or is the camera broke?
