3. Check that there are no scratches or cracks
on the marine case every time you use it.
The marine case must withstand water
pressure with use. Repeated exposure to
pressure eventually leads to material fatigue,
which may result in damage of the marine
case. Every time you use the marine case,
check in advance that there are no scratches
or cracks. If you frequently use the marine
case, be sure to ask for maintenance at the
store of purchase. (There is a charge for
maintenance.)

liquid on a lens tissue paper
(commercially available) or a
clean cloth, and apply on the inner
side of the front glass.
Marine case
Drying agent
Prevents fogging inside the marine case.
Insert it at the back of the base attached to the
camera.
¹ The moisture absorption ability of drying
agent that has previously been used may
deteriorate depending on the conditions of
use. As such, we recommend that the drying
agent be replaced each time.

Caution
Maintenance on the marine case
z The camera may fall out if the buckles are
opened with the front glass facing down.
z If you cannot avoid opening the marine case at
the diving location, pay attention not to let
water droplets from your hair or your body
enter the case.
Always perform maintenance on the marine case
after you have finished recording.
Salt crystal or dirt will accumulate inside the
marine case if maintenance is not performed, and
this can cause water leakage.
Wash the marine case in water
while it is still sealed

z Pour in fresh water until the marine case is
completely submerged in the container, and
shake the marine case in the upward,
downward, left and right directions.

Remove the O-ring, and wipe off salt, sand
and other foreign matter.
z Also wipe the groove in which the O-ring
was inserted, and the part of the marine
case that was in contact with the O-ring,
and allow them to dry.
¹ For details on handling and storing the
O-ring, refer to the “O-ring Maintenance
Manual”.
E
-> Proceed to Aerforming salt removal
Performing salt removal
If the marine case was used in the sea, submerge
the marine case in fresh water for at least 1 hour
to remove salt.
Prepare a container that contains fresh
water that is five times more than the
volume of the marine case.
z The container must be big enough to allow
the marine case to submerge fully.
z If only small containers are available, pour
in fresh water that is equivalent to at least
five times the volume of the marine case
over a few times.

O-ring
What is O-ring?
● O-ring is a type of seal used to make underwater
cameras, strobes and other diving instruments,
waterproof.
O-ring
It looks like a big, thick rubber band.
● The O-ring is an important component that protects the
camera from water by keeping the marine case airtight.
When should the O-ring be inspected?
● As a general rule, each time before using
(Salt crystals are formed when seawater that entered the O-ring groove dries.
Salt crystals just like sand, can cause water leakage.)
● When shooting on the sandy seabed, or when the camera is placed on the
sand
● When not used for a long period of time
Inspection and maintenance of the O-ring
● Remove the O-ring
¹ To inspect the O-ring, use the pick supplied to remove it from the O-ring groove.
¹ Do not use knifes, scissors, tweezers, and other sharp objects which might damage the
O-ring and the O-ring groove.
● Check for hair, dirt, sand, salt, dust, and other foreign matter
¹ Even small foreign matter can cause water leakage.
● Check for foreign matter that are not visible by rubbing gently with your
fingers
¹ Be sure to remove all foreign matter.
JDirt
JSand
JHair
JDust
JSalt
JLint
● Wipe off any residual grease
Wipe off gently with a soft cloth or tissue paper.
¹ After wiping, make sure the fiber of the cloth or tissue paper is not adhered to the
O-ring.
● Check for any deforms (distorted, crushed), cracks or cuts on the surface
Cracks on the O-ring can be easily spotted by bending and
twisting it gently.
Cracks
¹ Never use an O-ring if it is deformed, cracked, or
damaged in any way. It can cause water leakage.
¹ Replace the O-ring with a brand new one every year.
Even if there are no nicks, cracks, etc., its effectiveness
will deteriorate due to wear.

JDistortion
JCrushed

● Apply silicone grease on the O-ring
The O-ring needs to be re-greased when its surface appears dry.
Be sure to remove the O-ring and apply the silicone grease on it.
A Squeeze about 1 cm onto your finger
B Apply it on the O-ring by holding the O-ring with your fingers.
If the amount applied is not enough, repeat the above step.
¹ Make sure that you do not apply too much grease!
Dirt and dust will easily adhere if too much grease is applied.
Neither will it improve the waterproofing. Be sure to apply moderately.
¹ Do not pull too strongly!
This will cause deformation.
O-ring
About 1 cm
Grease
● Check for any foreign matter in the O-ring groove
Inspect thoroughly as it is usually not visible.
Grains of sand and crystallize salt may be stuck inside.
Remove them carefully by either using an air spray or a swab.
¹ Make sure the fibers of the swab are not adhered.
Swab
Groove
● Insert the O-ring after inspection
Make sure no foreign matter is adhered when placing the greased O-ring back to the
groove.
Do not pull too strongly, and make sure the O-ring is placed evenly and not twisted.
<POINT>
Insert from the four diagonal corners
and smooth out evenly.

Storing the O-ring
● If you do not intend to use the marine case for a long period of time,
remove the O-ring and allow it to rest.
A Remove the O-ring.
¹ Be sure to use the pick supplied.
B Wipe off the grease gently.
C Check for any foreign matter that might be adhered to it.
D Put the O-ring inside a clean plastic bag, and store in a way that it will not be subject to
stress.
¹ Do not put in moth balls and other insect repellents.
¹ Do not leave the O-ring as-is in the marine case for a long period of time.
It may deform due to heat and pressure resulting from the locked and tightened state.
¹ Do not store in hot and humid locations.
This will cause the O-ring to deteriorate more quickly.
