Operating Environment
Since this camera is water-resistant, dust-resistant, and
shock-resistant, you can handle it while your hands are wet,
you can wash it with water, and even use it in the areas listed
below.
•At the beach
•Around a pool
•On a river bank
•On a ski slope
•In the rain
Operating Precautions
•Always make sure that the battery cover and terminal
cover are closed securely.

INTRODUCTION
14
Wipe the camera dry after it becomes wet.
•Water remaining on the camera after it becomes wet can
collect in the seams between controls and the camera
body, etc. Carrying the camera around while it is wet can
cause water to leak from the seams and cause your cloth-
ing or bag to become wet. Make sure you carefully wipe all
remaining water from the camera after it becomes wet.
Location Precautions
Note the following precautions whenever using the camera
in the locations indicated.
•At the beach or around a swimming pool
Never put the camera down directly on the sand. Should
seawater, pool water, or sand ever get on the camera,
rinse it off in a sink or other container filled with still tap
water.
•In the rain
The camera is designed so it can withstand moderately
strong rain ranging from about 10mm per hour or less to
about 15mm per hour. Never open the battery cover or ter-
minal cover while the camera is in the rain or while your
hands are wet.
•Washing
The camera can be washed with a relatively weak stream
clean water from a standard household tap under the fol-
lowing conditions.
Outlet Diameter: 20mm (0.8˝)
Maximum Pressure: 98kPa (1kgf/cm2)
Rub the camera lightly with your hands, and never use a
brush, or other implement.
IMPORTANT!
• The above precautions are not exclusive. Even follow-
ing the above precautions does not guarantee that ex-
posure to certain conditions will not cause problems
with proper camera operation. Repair of the camera
may be impossible or may be charged to you if it is
determined that a problem is due to misuse of the
camera by you.

INTRODUCTION
15
General Precautions
• Even very fine pieces of foreign matter (a single hair, a
single grain of sand, etc.) on the battery cover or terminal
cover O-ring can result in incomplete sealing and problems
when the camera is immersed in water. Whenever closing
a cover, use a soft, dry cloth to wipe off all water droplets,
sand, dirt, etc.
• Whenever there is seawater, detergent, sand, mud, or
other similar matter on the camera, rinse it in a off sink or
other container filled with still tap water. Do not use run-
ning water from a tap, which creates the risk of dirt or sand
working its way under buttons and into other openings. Al-
ways make sure that the battery cover and terminal cover
are closed securely.
• Use a soft, dry cloth to wipe any water remaining on the
camera after it becomes wet.
*Do not carry the camera around while it is wet. Doing so creates
the risk of internal shorting.
*Moisture on the camera can freeze in very cold environments. Ice
left on the camera can lead to malfunction. Do not allow moisture
to remain on the camera under cold conditions.
• Though the camera is designed to withstand the effects of
dropping and impact occurring during normal daily use,
very strong impact due to very rough handling such as
throwing the camera or dropping it from excessive heights
can result in serious damage. Even if a drop does not result
in functional problems, it can cause scratching and other
cosmetic damage to the camera.
• To ensure proper water resistance, you should have the
battery cover and terminal cover O-rings replaced every
two years, regardless of their condition. Note that you will
be charged for O-ring replacement. Contact your nearest
authorized CASIO maintenance service provider to have
the O-rings replaced.

INTRODUCTION
16
Inspecting the Cover O-rings
The battery cover and terminal cover are fitted with rubber
gaskets called “O-rings” that keep water from entering the
camera. Even very fine pieces of foreign matter (a single
hair, a single grain of sand, etc.) on an O-ring can result in
incomplete sealing and allow water to leak inside. Note that
water leaking inside the camera results in unrepairable dam-
age. Make sure you periodically inspect the O-rings, O-ring
grooves, and contact surfaces for cracks, deformation, dirt,
and dust. Use a soft, dry cloth to wipe all dirt and dust from
the O-rings and their contact surfaces.

surface
If you find dirt on an O-ring...
• Carefully remove the O-ring. Use a cotton swab moistened
with water to wipe dirt from the O-ring groove and contact
surface.
• Wash the O-ring in water, dry it off, and then replace it into
the O-ring groove.
• Make sure the O-ring enters the groove securely, as far as
it will go.
IMPORTANT!
• Never pull on an O-ring with excessive force or try to
expand an O-ring.
• Never apply grease or oil to an O-ring.
• Never use a pointed object to remove an O-ring. Do-
ing so can damage the O-ring and lead to leaking.
• Excessive twisting of an O-ring can cause leaking. Al-
ways handle O-rings with care.
• Have an O-ring replaced whenever it becomes cut,
damaged, or deformed. You should also have O-rings
replaced every two years, regardless of their condi-
tion. Take your camera to your nearest CASIO main-
tenance service provider to have O-rings replaced.
Note that you will be charged for O-ring replacement.
If you frequently use your camera where it is exposed
to water, sand, or dust, we recommend that you have
the O-rings replaced once a year.

INTRODUCTION
17
Before putting your camera away after
using it...
After using your camera in a location where it was exposed
to sand, mud, or water, you should wash it off before opening
the battery cover or terminal cover.
IMPORTANT!
• Use plain tap water that is 30°C or lower to wash the
camera.
• The interior of the camera is not water-resistant. Make
sure that the battery cover and terminal cover are se-
curely closed before washing the camera.
1. Immerse the camera in water and wash it.
• Fill a bucket or other container with water and im-
merse the camera. Rub the camera lightly with your
fingers to remove dust, dirt, sand, and other matter.
• Never rub the surfaces of the lens, viewfinder, monitor
screen, or flash while there is dirt on the camera.
2. Wipe the camera dry.
• Use a clean, dry, soft cloth to wipe off the camera, and
leave it in a shady place to dry.
• Never leave the camera in direct sunlight to dry it off.
IMPORTANT!
• Never use detergent, hot water, or strongly running
water to clean the camera. Doing so creates the risk of
leaking and malfunction.
• Never swing the camera around to remove water, or
use a dryer or other intense heat to dry it.
• Never try to wash the camera in a washing machine.
• If your camera becomes very dirty, contact your near-
est authorized CASIO maintenance service provider.

Precautions
General Precautions
Be sure to observe the following important precautions
whenever using the GV-20.
All references in this manual to “this camera” and “the cam-
era” refer to the CASIO GV-20 Digital Camera.
• Never try to take pictures or use the built-in display while
operating a motor vehicle or while walking. Doing so cre-
ates the danger of serious accident.
• Never try to open the case of the camera or attempt your
own repairs. High-voltage internal components create the
risk of electric shock when exposed. Always leave mainte-
nance and repair work up to authorized CASIO service pro-
viders.
• Never fire the flash in the direction of a person operating a
motor vehicle. Doing so can interfere with the driver’s vi-
sion and create the danger of accident.
• Never fire the flash while it is too close to the subject’s
eyes. Intense light from the flash can cause eye damage if
it is fired too close to the eyes, especially with young chil-
dren. When using the flash, the camera should be at least
one meter from the eyes of the subject.
• Keep the camera away from water and other liquids, and
never let it get wet. Moisture creates the danger of fire and
electric shock. Never use the camera outdoors in the rain
or snow, at the seashore or beach, in the bathroom, etc.
• Should foreign matter or water ever get into the camera,
immediately turn power off, unplug the AC adaptor from the
power outlet, and contact your dealer or nearest CASIO
service provider. Using the camera under these conditions
creates the danger of fire and electric shock.
• Should you ever notice smoke or a strange odor coming
out of the camera, immediately turn power off and unplug
the AC adaptor from the power outlet. Using the camera
under these conditions creates the danger of fire and elec-
tric shock. After making sure there is no more smoke com-
ing from the camera, take it to your nearest CASIO service
provider for repair. Never attempt your own maintenance.
• At least once a year, unplug the AC adaptor from the power
outlet and clean the area around the prongs of the plug.
Dust build up around the prongs can create the danger of
fire.
• If the camera’s case should ever become cracked due to
dropping it or otherwise subjecting it to rough treatment,
immediately turn power off, unplug the AC adaptor from the
power outlet, and contact your nearest CASIO service pro-
vider.
• Never use the camera inside of an aircraft or in any other
areas where its use is prohibited. Doing so can result in an
accident.
• Physical damage and malfunction of this camera can
cause the image data stored in its memory to be deleted.
Be sure to always keep backup copies of data by transfer-
ring them to personal computer memory.

INTRODUCTION
19
• Never open the battery compartment cover, disconnect the
AC adaptor from the camera or unplug it from the wall
socket while recording images. Doing so will not only make
storage of the current image impossible, it can also corrupt
other image data already stored in camera memory.
Data Error Precautions
• Your digital camera is manufactured using precision digital
components. Any of the following creates the risk of cor-
ruption of data in camera memory.
— Opening the battery cover or disconnecting the AC
adaptor while data is being saved
— Removing a memory card while image recording is in
progress
— Removing batteries, unplugging the AC adapter, open-
ing the battery cover, or removing the memory card
while the operation lamp is still lit after camera power is
turned off
— Disconnecting the data communication cable
— Using low batteries
— Other abnormal operations
Any of the above can cause a MEMORY CARD ERROR!
message or NOT FORMATTED message to appear on the
monitor screen. See page 85 for information about what you
need to do when these messages appear.
Operating conditions
• This camera is designed for use in temperatures ranging
from 0°C to 40°C.
• Do not use or keep the camera in the following areas.
— In areas subject to direct sunlight
— Near air conditioners, heaters, or other areas subject to
temperature extremes
— Inside of a closed vehicle, especially one parked in the
sun
— In areas subject to strong vibration

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.
Condensation
• When you bring the camera indoors on a cold day or other-
wise expose it to a sudden change of temperature, there is
the possibility that condensation can form on the exterior or
on interior components. Condensation can cause malfunc-
tion of the camera, so you should avoid exposing it to con-
ditions that might cause condensation.
• To keep condensation from forming, place the camera into
a plastic bag before moving it into a location that is much
warmer or colder than your current location. Leave it in the
plastic bag until the air inside the bag has a chance to
reach the same temperature as the new location. If con-
densation does form, remove the batteries from the cam-
era and leave the battery cover open for a few hours.
