Turning on the Power

When you turn on the power switch and the date/time setting screen
appears, see page 29 to set the date/time.
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 turn <1>/<2> the power switch at a short interval, the
<f> icon might not be displayed. This is normal and not a
problem.
About Auto Power Off

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 [5 Auto
power off] setting (p.131).
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.
<1> : The camera turns on.

position when not using the
camera.
