How to check if my camera is on or off
Press the button on top of the camera for 5 seconds. If the LED on the front of the camera flashes red after 5 seconds and then goes off when you lift your finger off the button, then the camera is OFF.
To turn on the camera, repeat the above sequence till the LED on the front of the camera flashes green. Now take your finger off the power button as the camera is now ON.
NB: The above states will only display if your camera has sufficient battery power.
