INTRODUCTION

About the camera’s backlight…
• The camera is equipped with a fluorescent light source to
provide the back lighting for its LCD.
• The normal service life of the backlight is approximately six
years, when the camera is used for about two hours a day.
• Should the LCD image appear abnormally dark, take the
camera to your dealer or an authorized CASIO service pro-
vider to have the light source replaced. Note that you will
be charged for this replacement.
• Under very cold conditions, the backlight may require more
time than normal to light, or reddish bands may appear in
the displayed image. These conditions do not indicate mal-
function, and normal operation should return at higher tem-
peratures.
Lens Precautions
• Fingerprints, dust, or any other soiling of the lens can inter-
fere with proper image recording. Never touch the lens with
your fingers. You can remove dust particles from the lens
surface by using a lens blower to blow them off. Next, wipe
the surface of the lens with a soft lens cloth.
• The lens of this camera extends from its body when you
turn on power and retracts when you turn off power. Take
care not to subject the lens to undue force or impact, and
never set the camera face down so the lens is in contact
with a tabletop, etc. Be sure to remove the lens cap before
turning on the camera.
• If you align the power/function switch with while the
lens cap is on the lens, the message “LENS CAP” appears
on the display and camera power turns off automatically. If
this happens, remove the lens cap and try again.
• Never remove the camera’s batteries or unplug its AC
adaptor while the lens is extended. Doing so leaves the
lens extended, and creates the risk of lens damage.
