2. Advance Check of the Case
Advance test before use
This Case has been the subject of thorough quality control for the parts
during the manufacturing process and thorough function inspections
during the assembly. In addition, a water pressure test is performed
with a water pressure tester for all products to confirm that the
performance conforms to the specifications. However, depending on
the carrying and storage conditions, the maintenance status, etc., the
waterproof function may be damaged.
Before diving, always perform the following advance test and the water
leakage test after installation of the camera.
Advance Test
1. Before installing the digital camera in the Case, immerse the
empty Case to the intended water depth to confirm that there is
no water leakage.
2. Main causes of water leakage are as follows.
ț The O-ring has not been installed.
ț A part of the O-ring or the entire O-ring is outside the specified
groove.
ț O-ring damage, cracks, deterioration or deformation.
ț Sand, fibers, hair or other foreign matter sticking to the O-ring,
the O-ring groove or the O-ring contact surface on the front lid.
ț Damage to the O-ring groove or the O-ring contact surface on
the front lid.
ț When closing the Case, check for catching of the hand strap and
silica gel after the above causes have been eliminated.
: • The most suitable method for checking water leakage is
to immerse the Case to the intended water depth. When
this is difficult, water leakage also can be checked at a
shallow depth with no water pressure. Do not feel that
this is troublesome, but perform this test.
• If the advance test should show water leakage with
normal handling, stop using the Case and contact your
dealer or an Olympus service station (listed on the rear
page of this instruction manual).
E-18
3. Install the digital camera.
Check the digital camera.
Check the digital camera before loading it in the Case.
Battery Confirmation
As the LCD monitor is used for picture confirmation while taking
pictures under water, the battery life becomes short.
Confirm that the remaining battery capacity is sufficient.
Do not use alkaline batteries, as it is quite possible that they will
become unusable during a dive.
Note: • In order to avoid losing shutter chances due to an exhausted
battery, you should always replace a battery with a fully
charged battery before each dive.
Confirmation of the Remaining Number of Pictures to be Taken
Confirm that the image storage has a sufficient remaining number
of pictures to be taken.
Removing the carrying strap and lens cap from the digital camera
If the digital camera has a carrying strap and lens cap attached, be
sure to remove them before inserting the digital camera into the
case.
:
• If the digital camera is inserted into the case without
removing the carrying strap and lens cap, the case
cannot be closed properly and water penetration may
result.
• Be careful when removing the carrying strap and lens
cap from the digital camera. Olympus will not assume
any liability for any damage that may result from
dropping the camera.
Loading in the Case
Which digital cameras can be loaded?
This product (PT-022) is exclusively used for the CAMEDIA C-760
Ultra Zoom/C-770 Ultra Zoom.
E-19
Check the operation of the camera.

direction ). When not using the buckle opener, hold the buckle opening
lever with your thumb and index finger from the side and pull it up slowly.
①�
②�
Pull up the mode dial of the case.
Pull up the mode dial of the case until it
stops, so that it does not interfere with the
mode dial of the digital camera.
Load the digital camera.
Quietly load the digital camera into the
Case, taking care that the projecting
part of the zoom lever of the digital
camera properly fits into the recessed
part of the zoom lever of the Case.
:
•
•
Make sure that the flash is closed when loading the
digital camera.
Confirm that the projecting part of the zoom lever of the
digital camera is set securely to the zoom lever notch on
the inside of the case. When the setting is not secure,
the loading of the digital camera is not complete and
closing of the rear lid of the case may not be possible or
zoom does not function even when the zoom lever is
operated, so that caution is required.
Insufficient sealing will cause water leakage.
E-20
Set the mode dial.
After the digital camera has been
loaded, push down the mode dial
of the case from the upper surface
of the case and set it so that the
lower part of the mode dial of the
case on the inside of the case fits
properly onto the upper part of the
mode dial of the digital camera.
Advice • After setting the mode dial of the case, set the power of the digital
camera to 'OFF', and before sealing the case, operate the mode
dial and confirm that the mode of the digital camera is switched.
Insertion of silica gel
Before sealing the Case, insert the accessory silica gel bag for
prevention of fogging between the bottom of the camera and the
Case. Insert the bag with the glued longer side to the inside.
Pay attention to the orientation.
:
•
Insert the silica gel all the way at the specified location
and with the specified orientation. When the orientation
is not correct, the silica gel bag will be caught when the
Case is sealed and water leakage will be caused.
When it is tried to seal the Case with the bag inserted only
part of the way, the silica gel bag will be caught by the O-
ring and water leakage will be caused.
•
•
Once silica gel has been used, the moisture absorption
performance will be impaired. Always exchange the
silica gel when the Case is opened and closed
.
E-21
Check the loading status.
Always perform the following final checks before sealing the Case.
ț Has the digital camera been loaded so that the zoom lever
operates properly?
ț Has the silica gel been inserted all the way at the specified position?
ț Has the O-ring at the Case opening part been installed properly?
ț Are the O-ring and the O-ring contact surface on the front lid free of
dirt and other foreign matter?
Seal the Case.
When the rear lid is closed
(quietly, so that the O-ring will

any waterdrop sticking to the
Case. Use air or a soft cloth not
leaving any fibers to thoroughly
wipe any waterdrop etc. from
the joint between the front and
rear lid, the shutter lever, the
palm grips, and the buckles.
: • Especially when waterdrops remain between the front and
the rear lid, they may spill to the inside when the Case is
opened. Take special care to wipe off all waterdrops.
• When opening the Case, take sufficient care that no
water will drop from your hair or body onto the Case
and the camera.
• Before opening the Case, make sure that your hands
or gloves are free of sand, fibers, etc.
• Do not open or close the Case at locations where water
or sand is to be sprayed. When this cannot be avoided
because you have to exchange the battery or the
image storage, place a sheet downwind from some
object and take care that no water or sand is sprayed.
• Take care not to touch the digital camera or the battery
with hands wet with sea water.
Note

facing down, dirt or other foreign matter may be attached
to the O-ring or the O-ring contact surface and may
cause water leakage during the next dive.
• Please read the operation manual for the digital camera
for the storage of pictures etc.
• Take special care so that no water drops get onto the
camera.
E-28
Wash the Case with pure water.
After use, seal the Case again after taking out the camera and wash it
sufficiently in pure water as soon as possible. After use in sea water, it is
effective to immerse it for a fixed time in pure water to remove any salt.
: • Water leakage may be caused when a high water
pressure is applied locally. Before washing the Case
with water, take out the digital camera from it.
• Operate the shutter lever and various buttons of this
product in pure water to remove salt adhering to the
shaft. Do not disassemble for cleaning.
• Drying the Case with adhering salt may impair the
function. Always wash off any salt after use.
Dry the Case.
After washing with pure water, use a soft cloth without any salt on it and
not causing any fibers to wipe off any waterdrop and dry the Case
completely at a well ventilated location in the shade.
: • Do not use hot air from a hair drier or the like for drying
and do not expose the Case to direct sunlight, as this may
accelerate deterioration and deformation of the Case and
deterioration of the O-ring, leading to leakage of water.
When wiping the Case, take care not to cause scratches.
E-29
6. Maintaining the Waterproof Function
Remove the O-ring.
Open the Case and remove the O-ring from the Case.
Removal of the O-ring
ᕃ Insert the O-ring removal pick between the O-ring and the wall of the
O-ring groove.
ᕄ Move the tip of the inserted pick under the O-ring. (Take care not to
damage the O-ring groove with the tip of the pick.)
ᕅ Hold the O-ring with your fingertips after it has come out of the
groove and remove it from the Case.
Remove any sand, dirt, etc.
After visually checking that dirt has been removed from the O-ring,
checking for attached sand and other foreign matter, as well as for
damage and cracks can be done by squeezing the entire circumference
of the O-ring lightly with your fingertips.
E-30
Using a clean cloth free of fibers, dirt, etc., a piece of lint-free tissue
paper or a soft toothbrush, remove any foreign matter attached to the
grooves of the O-rings. Also remove sand and dirt particles attached to
the O-ring contact surfaces on the case.
: • When a mechanical pencil or a similar other sharp object
is used to remove the O-ring or to clean the inside of the
O-ring groove, the Case and the O-ring may be
damaged and water leakage may be caused.
• When the O-ring is checked with the fingertips, take care
not to stretch the O-ring.
• Never use alcohol, thinner, benzene or similar solvents
or chemical detergents to clean the O-ring. When such
chemicals are used, it is to be feared that the O-ring will
be damaged or that its deterioration will be accelerated.
E-31
Install the O-ring.
Confirm that no foreign matter is attached, apply a thin coat of the
accessory grease to the O-ring, and fit the O-ring into the groove. At
this time, confirm that the O-ring does not stick out from the groove.
How to Apply Grease to the O-ring
Apply the
exclusive
lubricant to each
O-ring.
Make sure that your fingers and the O-
ring are free of dirt, and squeeze about
5 mm of lubricant onto a finger. (5 mm
is the most appropriate amount.)
1
2
3

Surround the lubricant with three
fingers and spread it over the ring. Be
careful not to use excessive force as
this may stretch the O-ring.
Spread the
lubricant all over
the O-ring.
After spreading the lubricant, check
visually and by touch that the O-ring is not
scratched and that its surface is flat. If it is
damaged in any way, replace it with a
brand-new O-ring.
Check that the
O-ring is free of
scratch or
unevenness.
Apply lubricant on
the O-ring contact
surface.
Use the lubricant remaining on the
fingers to clean and lubricate the
case's contact surface.
:
• Always perform maintenance of the waterproof
function even when the Case has been opened to
exchange the battery or the image storage during
shooting. Neglecting this maintenance may become
the cause of water leakage.
• When the Case is not to be used for a long time,
remove the O-ring from the groove to prevent
deformation of the O-ring, apply a thin coat of silicone
grease, and store it in a clean plastic bag or the like.
• When drying is done with salt attached, it is likely that
a function impairment will be caused. After use,
always wash off any salt.
E-32
Maintenance of the threaded sections on the
TTL cable and TTL cable connector
If the threaded sections used to connect the TTL cable to the TTL cable
connector are not maintained properly, salt and other seawater residue
may adhere the TTL cable and prevent it from being disconnected.
After use in seawater, clean off any salt, sand, or other residue as soon
as possible, then dry the equipment thoroughly. Clean the threaded
sections with a cotton swab and apply a thin, uniform layer of O-ring
silicon grease (provided with this case).
Clean and apply O-ring
silicon grease to these
sections.
Maintenance of the TTL Connector Cap
After removing the TTL connector cap from the waterproof cap, be sure
to clean and grease the O-ring.

7. Appendix
Q & A on the use of the PT-022
Q1: Which digital cameras can be used?
A1 : The PT-022 is only for the models C-760 Ultra Zoom/C-770 Ultra Zoom.
Q2: What cautions must be observed when loading the digital camera into
the Case?
A2 : Pay special attention to the following items when loading the camera into
the Case.
(1) Check that the remaining capacity of the battery in the digital camera is
sufficient.
This should be checked as the LCD monitor is used under water, and the
battery consumption becomes faster.
(2) Check the remaining number of pictures on the image storage.
Please use a card with a sufficient remaining number in order to reduce
the number of times the Case has to be opened and closed.
(3) Remove the strap from the digital camera.
When the camera is loaded without removing the strap, the strap may
get caught when the Case is sealed and this will cause water leakage.
(4) Before sealing the Case, confirm that the O-ring has been installed
properly in the groove in the rear lid of the Case.
(5) Confirm that the O-ring and the O-ring contact surface on the front lid are
free of dirt, hairs, and other foreign matter.
(6) Insert the silica gel for defogging. Please use silica gel for the Olympus
Case.
(7) Finally install the special balance weight to the tripod mounting thread.
Q3: What cautions must be observed when using and storing the Case?
A3 : Pay special attention to the following items.
(1) When the O-ring contact surface is pressed strongly from the outside of
the Case, or when the Case is twisted, the waterproof function may be
impaired and water leakage may be caused.
(2) When the Case is used, left or stored at the following locations, defective
operation or trouble may be caused. Always avoid such locations.
(a) Places where the Case can reach high temperatures under direct
sunlight or in a car, places with extremely low temperatures, and
places with extreme temperature variations
(b) Places with open fire
(c) Places with volatile substances
(d) Places with vibrations
E-35
(3) In case of the following handling with a camera loaded into the Case,
trouble or breakage may be caused for the Case and/or the loaded
camera. Always avoid such handling.
(a) Hitting other objects
(b) Dropping
(c) Placing heavy objects on top of the Case
(4) When the Case is not used for a long time, trouble from formation of
mold etc. may be caused. Before use, confirm the operation of all
operation parts and perform the advance test and the final test.
Q4: What cautions must be observed when opening and closing the Case?
A4 : Pay special attention to the following items.
(1) Do not open and close the Case at locations with water spray or sand
spray.
(2) Wipe off all waterdrops from the gap between the front lid and the rear lid
and around projections and recesses such as the buckles. When this is
not done, entry of waterdrops into the Case is to be feared at the time of
opening and closing.
(3) When opening the Case, take care that no water will drip from your hair
or body into the Case or onto the camera.
(4) When the Case is open, check that there is no attachment of sand, fibers
or other foreign matter to the O-ring and the O-ring contact surface on
the front lid.
(5) Do not touch the camera or the image storage with your hands to which
sea water is sticking.
(6) If you should detect waterdrops or other signs of water leakage while
shooting, immediately end the dive, perform the water leakage test
again, and confirm that there is no leakage. If the camera is wet, wipe off
any moisture and check the operation.
Q5: How should the Case be handled after use?
A5 : After use, take out the camera as soon as possible and wash the Case
with pure water. In case of use in the ocean, it is effective to immerse the
Case for a certain time in pure water to remove any salt. Operate the
buttons and levers under water to turn the shafts and wash off any salt.
After washing, use a dry cloth without any salt on it to wipe off any
moisture and dry the Case in the shade. Do not use hot air from a hair
drier or the like and do not dry the Case under direct sunlight. Exposure
to high temperatures or direct sunlight may cause deformation,
discoloration or breakage of the Case and deterioration of the O-ring.
Wipe the inside of the Case with a soft cloth not causing any fibers.
Remove the O-ring, wipe off any salt, sand, dust, etc., and also clean the
O-ring groove and the O-ring contact surface in the same way and then
E-36
dry them. When an object with a sharp tip is used to remove the O-ring
from the groove, the O-ring may be damaged and water leakage may be
caused. Always use the accessory pick for O-ring removal.
Q6: How should I take pictures under water?
A6 : Please observe the following items for shooting under water.
(1) Fix the case with the accessory hand strap to your wrist.
(2) When you place a finger onto the lens window, the finger will appear in
the photo. Pay attention to the position of your fingers when holding the
Case.
(3) When pressing the shutter lever, hold the Case securely with both hands
and operate the lever quietly to prevent camera shake.
(4) Look through the LCD monitor window on the rear of the Case to confirm
the picture and then press the shutter lever. Please note that the
viewfinder cannot be used, When the LCD monitor is used, the battery is
exhausted earlier. In order to avoid losing shutter chances due to an
exhausted battery, please always replace a battery with a fully charged
battery before each dive.
Q7: How can I check for water leakage?
A7 : For confirmation, perform the advance test and the final test after loading
the camera. The advance test with immersing the Case without the
camera to the intended use depth to check for water leakage is the most
accurate test, but when this is difficult, it is safer to perform this test even
at a depth of 1 m or in a bathtub. The final test also can be performed in
a bathtub or a bucket.
Q8: What are the causes for entry of water?
A8 : The main causes for the entry of water are shown below. Please check
them most carefully.
(1) Forgetting to install the O-ring
(2) The O-ring is partly or completely outside the groove.
(3) Damage, deterioration, or deformation of the O-ring
(4) Sand, fibers, hair or other foreign matter on the O-ring
(5) Sand, fibers, hair or other foreign matter on the O-ring groove or the O-
ring contact surface
(6) Catching of the strap, the bag of silica gel, etc. at the time of sealing the
Case
(7) Throwing the Case from a boat into the water, jumping with the Case into
the water, or other sudden application of strong forces onto the Case.
When entering the water, hand the Case over quietly or avoid impacts in
other ways.
E-37
Q9: What are the important points for O-ring maintenance?
A9 : Please observe the following items.
(1) Never use alcohol, thinner, benzene or similar organic solvents or
chemical detergents to clean the O-ring. When such chemicals are used,
it is to be feared that the O-ring will be damaged or that its deterioration
will be accelerated.
(2) Use the original Olympus silicone O-ring grease (white cap). The grease
attached to Cases up to PT-008 (red cap) and the grease of other
companies are not suitable for this silicone O-ring, and use of such
grease may cause deterioration of the surface and impairment of the
waterproof function.
(3) In order to avoid deformation of the O-ring when the Case is not used for
a long time, remove the O-ring from the Case, apply a thin coat of the
special grease, and store the O-ring in a clean plastic bag. For reuse,
confirm that the O-ring is free of damage and cracks, that it has sufficient
elasticity, that the surface is free of stickiness and other abnormalities,
and use it after applying a thin coat of the special grease. Excessive
application of grease does not improve the waterproof function or the
permissible withstand pressure. However, it may facilitate attachment of
sand, dirt, etc.
A thin, uniform coat produces the best result.
(4) The O-ring is a consumable product. Replace it at least once a year.
(5) Deterioration of the O-ring is accelerated by the use conditions and the
storage conditions. Replace the O-ring immediately by a new one if it
shows signs of damage, cracking or loss of elasticity.
