* The Marine Pack you are using may not necessarily be the one in the
illustrations.
What is the O-ring?
The O-ring ensures the waterproof qualities of the Marine Pack or other
equipment.
O-ring maintenance is very important. Failure to
carry out O-ring maintenance according to the
instructions may lead to water leakage and cause
the Marine Pack to sink.

Handling the O-ring
Fit the O-ring
Avoid fitting the O-ring in dusty or sandy locations.
1 Remove the O-ring.
To remove the O-ring, press it lightly and slide it in the direction of the
arrow as illustrated. The O-ring has enough slack to be able to be removed
easily. Be careful not to scratch the O-ring with your fingernail.
2 Inspect the O-ring.
• Check carefully for the following. If found, wipe off with a soft cloth or
tissue paper.
– Is there any dirt, sand, hair, dust, salt, thread scraps, etc. on the O-ring?
– Is there any old grease on the O-ring?
• Lightly run your fingertip around the O-ring to check for any invisible
dirt.
• Be careful not to leave any cloth or tissue paper fibers on the O-ring after
wiping it.
• Check the O-ring for cracks, skewing, distortion, fine splitting, scratches,
sand inclusion, etc. Replace the O-ring if it is cracked or scratched.

3 Inspect the O-ring groove.
Carefully remove any grains of sand or hardened salt that get into the
groove.
4 Inspect the contact surface on the other side of the O-ring in
the same way.
5 Apply the special grease supplied to the O-ring.
• Use your fingertips to thinly coat the entire surface of the O-ring with a
small drop of grease, as illustrated above.
• Make sure there is always a thin coating of grease on the surface of the
O-ring. Grease protects the O-ring and prevents wear.
Grease
Only use the grease supplied. Other kinds of grease will damage the O-
ring and cause water leakage.
6 Fit the O-ring into the groove of the Marine Pack.
Fit the O-ring evenly into the groove paying attention to the following
points:
– Check for dirt on the O-ring.
– Check the O-ring is not twisted or protruding.
– Do not pull the O-ring.

Handling the O-ring (continued)
Final check
Check the O-ring again for any dirt, cracks or twisting, etc.
How to check for water leakage
Before installing the equipment, always close the marine pack and
immerse it in water to a depth of about 15 cm for about three minutes to
make sure no water leaks in.
PCAUTION
After taking photos near a sandy sea bottom or placing the camera on the
sand, remove the O-ring and inspect it.
Be sure to take a spare O-ring with you.
You can replace the fitted O-ring on location if
something goes wrong with it.
O-ring life
Replace each O-ring with a new one after one year of use.
Even if the O-ring is not cracked or scratched, deformation or wear
reduces its waterproof qualities.
