2Check the O-ring.
≥Check that there is no dirt, sand, hair, dust, salt crystals, lint or grease on the 
O-ring. If you find any of these, remove them with a soft, dry cloth.
≥There may be dirt on the O-ring that you cannot see. Check if there is any dirt by 
rubbing your finger over the O-ring.
≥Be careful not to leave any fibers from the dry cloth on the O-ring when wiping it.
≥Check that the O-ring is not ripped, twisted, squashed, frayed or scratched and 
that there is no sand sticking to it. Replace the O-ring in these cases.
3Inspect the O-ring groove.
≥Grains of sand or hardened salt crystals may get into the O-ring groove. 
Remove them carefully with an air spray or a cotton swab. If you use a cotton 
swab, be careful not to leave any fibers from it in the O-ring groove.
≥Inspect the front case groove as well as the rear case (side where O-ring is set) 
groove.

Preparation -Setting the O-ring- (continued)
4Apply the grease (supplied).
Apply O-ring grease to clean the surface of the O-ring and replenish the oil.
≥Apply a rice-grain size of grease (supplied) evenly to the O-ring with the tip of 
your finger. (Do not apply the grease with paper or a cloth. The fibers from the 
paper or cloth may stick to the O-ring.)
≥If there is too much grease on the O-ring, dirt and dust will stick to it causing 
water to leak in. Therefore, hold the O-ring between the balls of your finger and 
thumb and gently remove excess grease.
≥By applying the O-ring grease thinly and evenly, the O-ring fits flexibly to the 
groove of the marine case and keeps it airtight.
≥The surface of the O-ring may stretch or rip, causing a water leak, when an 
O-ring grease other than supplied is used, so always use the specified O-
ring grease.
5Fit the O-ring evenly into the O-ring groove. 
Check the following:
≥There is no dirt sticking to the O-ring.≥The O-ring has not come out.
≥The O-ring is not twisted.≥The O-ring is not stretched too much.

6Inspect the O-ring one last time.
Check the following one more time:
≥There is no dirt sticking to the O-ring.
≥The O-ring has not come out.
≥The O-ring is not twisted.
≥There are no scratches or squashed parts on the O-ring.
Thoroughly wipe any grease off your hands with a dry cloth. Afterwards 
wash thoroughly with fresh water.
7Close the buckle.
≥Check that no foreign materials are sticking to the outer surface of the O-ring or 
the buckle on the front case and then close the Case.
∫Notes
≥To keep the Case completely airtight, do not scratch the surface of the O-ring that 
comes into contact with the sides of the Case.
≥Never use an O-ring that has been scratched  or damaged by dirt etc. This will cause 
water leakage.
≥Each time you use the Case, remove the O-ring and check that there is no dirt, 
sand, hair or other foreign materials in the O-ring groove and then apply a thin coat 
of grease (supplied). If you apply too much grease, dirt and the dust may stick to the 
O-ring causing water leakage.
≥Be sure to bring a spare O-ring in case the O-ring that you are using becomes 
damaged or scratched.

Preparation -Checking the Case is Waterproof-
After setting the O-ring, check that no water leaks into the Case by 
submerging it in a water tank, bath tub etc. for about 3 minutes before 
attaching a digital camera.
≥Do not use the Case in water over 40 °C/104 °F. The heat may damage the Case or 
cause water leakage.
‘Carry out the same test after attaching the digital camera to the Case. (P15)
∫Notes
≥If bubbles rise from the Case when it is submerged in water or there is water inside 
the Case when you take it out of the water, there is water leakage. In these cases, 
consult your dealer.
≥If water leaks into the Case while you are using it and the digital camera is 
submerged in water, remove the battery immediately. Hydrogen gas can cause 
burning or explosion if there is a fire nearby.
≥If you dive quickly while holding the Case or throw the Case from a ship into the sea, 
some water leakage may occur because of hi gh pressure. This is not a malfunction 
of the Case. Always dive slowly into the water.
≥The Case is designed to be used at a depth of up to 40 m/130 feet. If you dive 
deeper than 40 m/130 feet, part of the Case may be damaged beyond repair.
≥When closing the Case, be careful that no foreign materials get caught between the 
O-ring and the O-ring groove. Even one strand of hair or one grain of sand can 
cause water leakage.

Preparation -Attaching the Digital Camera-
Read the notes on page 17 before attaching the digital camera.
Check that the ON/OFF Switch on the camera and the case is set to 
[OFF], and [Rec]/[Playback] selector switch is set to [
!].
≥Remove the strap from the digital camera.
1Push 2 up with your finger while sliding 1 to open the buckle.
2Attach the digital camera to the Case.
≥Be careful not to catch the shading hood  1.
3Insert the silica gel (supplied).
≥Always use new silica gel.

Preparation -Attaching the Digital Camera- (continued)
≥When inserting the silica gel, bend it as shown in the illustration below 
and then insert it as far as possible. If you close the Case with the silica 
gel not fully inserted, the silica gel will get caught in the O-ring causing 
water leakage.
≥If the air temperature is high and the water temperature is low, condensation 
may appear inside the Case. To prevent condensation, insert silica gel 
(supplied) inside the Case in advance. To prevent the Case from becoming 
fogged up, insert the silica gel about 1  to 2 hours before using the Case.
4Close the buckle.
‘
Check that the buckle is closed firmly.
Do not insert the strap etc. in the buckle.
5After you have attached the digital camera, check one more time that 
no water leaks into the Case. (P14)

∫Notes
≥Be careful not to get the shading hood dirty with fingerprints etc.≥Check one more time that the O-ring is fitted evenly into the O-ring groove.≥Avoid opening or closing the Case where ther e is a lot of sand or dust and in humid 
or wet places.
≥If there is a sudden change of humidity caused by moist air entering the Case, 
condensation may appear inside the Case.
≥To prevent condensation, set the digital camera in as dry a place as possible. Also, 
check that the silica gel (supplied) is sufficiently dry before inserting.
≥If sunscreen or suntan oil sticks to the Case, wash it off immediately with lukewarm 
water to prevent reduced waterproofness or discoloration.
∫ Attaching the weights
About using the weights
Attach the weights to adjust to the preferred buoyancy when using the marine case. 
Use them as necessary.
Refer to the following about buoyancy underwater.
1If you use the digital camera and the marine case only:
They will float slowly in fresh water or seawater. (Plus buoyancy)
2If you use the digital camera, the marine case and 1 weight:
They will float even more slowly in fresh water or seawater than 1. 
(Plus buoyancy)
3If you use the digital camera, the marine case and 2 weights:
They will sink slowly in fresh water or seawater. (Minus buoyancy)
How to attach the weights
If you use 1 weight, align the protruding part of 
the weight with the tripod receptacle on the 
marine case and then using a slotted screwdriver 
or similar, use the supplied weights attachment 
screw to attach to the tripod receptacle.
If you use 2 weights, align the projecting part of 
the second weight with the indented part of the 
first weight so that the weights do not overlap and 
then attach them to the tripod receptacle.
If a digital camera with GPS function is attached to the marine case, failure of 
positioning or other major errors may occur due to interference in the reception of 
radio waves from the GPS satellite.

After Use
After you have finished taking pictures, follow the steps below.
1Submerge the Case in fresh water for about 30 minutes or more 
without removing the digital camera to remove any salt crystals etc.
≥Press all the operation buttons etc. on the Case to wash away any 
seawater. If the salt crystals are not removed from the buttons etc., they 
will harden and the buttons will become inoperable.
≥Do not wash the Case with fast-running or pressurized water etc. as it may 
cause water leakage.
2Wipe the water with a dry cloth that has no salt crystals sticking to it 
and then dry the Case completely.
≥Do not dry the Case by exposing it to direct sunlight. This may discolor or 
damage the Case or may hasten deterioration of the O-ring.
3Open the rear of the case to remove the digital camera.
4Remove the O-ring from the Case and check that there is no dirt etc. 
in the O-ring groove.
5Check that there are no scratches etc. on the O-ring while you are 
applying the grease.
