Pressing this button causes the
Shooting Info Display to appear.
This shows some camera settings,
such as aperture, shutter speed,
and others. Pressing the Shutter
Release button lightly returns you
to the default Shooting mode.
Press this button again while view-
ing the Shooting Info Display to

Memory card access lamp. When
this light is blinking, the camera is
transferring data to the memory
card. Under no circumstances
should the memory card be
removed when this is lit. This can
damage your camera or the card
and will almost certainly result in a
loss of images.
Delete button. When reviewing
your pictures, if you fi nd some that
you don't want to keep, you can
delete them by pressing the button
marked with a trash can icon. To
prevent accidental deletion of
images, the camera displays a dia-
log box asking you to confi rm that
you want to erase the picture. Press
the Delete button a second time to
permanently erase the image.
You can format the SD card by
pressing the Metering mode button
and the Delete button at the same
time and holding them down for
about 2 seconds then release the
buttons and press them again.

White Balance/Help/Protect. This
button has the icon of a key and
question mark on it. Above it is WB.
This button actually has a few diff er-
ent uses. When in Shooting mode,
press this button and then rotate
the Main Command dial to change
the white balance (WB) setting.
Rotating the Sub-command dial
allows you to fi ne-tune the current
WB setting, making it warmer or
cooler. The WB setting can only be
changed when using the M, A, S,
and P settings. When in Playback
mode, this button is used to lock an
image to prevent it from accidentally
being erased. When viewing the
image you want to protect, simply
press this button. A small key icon is
displayed in the upper right-hand
corner of images that are protected.
When viewing the menu options or
when the camera is set to a Scene
mode, pressing this button displays
a help screen that explains the func-
tions of that particular menu option
or Scene mode.
