29 Getting Started
Restoring Previous Settings
The flash, shooting mode, and timer settings, as well as some
of the Capture Menu settings that you set, reset to their
default values after you turn the camera off. However, you
can restore your settings from the last time the camera was
on by holding down the button while turning the camera
on. The icons for the restored settings are then displayed in
the Live View screen.
Viewing the On-Camera Demo
This camera has a slideshow of its major features. You can
display the slideshow at any time by holding down the
Playback button for approximately three seconds.
The Image Display will go black for a moment before the
slideshow starts. To exit the slideshow at any time, press
the button.
