Turning on the Power

If the date/time setting screen appears when you turn on the power switch, see page 29 to set the date/time.

<1> : The camera turns on.

<2> : The camera is turned off and does not operate. Set to this position when not using the camera.

About the Automatic Self-Cleaning Sensor

Whenever you set the power switch to <1> or <2>, the sensor cleaning will be executed automatically. During the sensor cleaning, the LCD monitor will display <f>. Even during the sensor cleaning, you can still shoot by pressing the shutter button halfway (p.37) to stop the sensor cleaning and take a picture.

If you repeatedly turn the power switch <1>/<2> at a short interval, the <f> icon might not be displayed. This is normal and not a problem.

About Auto Power Off

To save battery power, the camera turns off automatically after about 30 seconds of non-operation. To turn on the camera again, just press the shutter button halfway (p.37).

You can change the auto power-off time with the menu’s [5Auto power off] setting (p.139).

If you set the power switch to <2> while an image is being recorded to the card, [Recording ...] will be displayed and the power will turn off after the card finishes recording the image.
