leakage.
When the product is flooding, interior pressure may build up. Please be careful when
opening the product as water may spurt out or the cap may open explosively and
cause injuries.
The product has been constructed with an airtight seal. When packing the product
for airplane travel, do not seal-up the product to alleviate pressure build up due to
atmospheric changes.
Do not open the product in a wet or sandy environment. Protect the interior from
moisture and debris in order to prevent malfunction or flooding.

Safety Precautions
Do not rest heavy weight on the product. It might deform the outer casing, damage
internal parts, make the waterproofing fail, or result in fire or electric shock.
Please note that some marks may be left on the camera scraping against the dials
or gears of the housing.
Handle the product carefully so as not to scratch the front port, the lens, the flash
window or the finder.
Always dry the front port, the lens, the flash window or the finder using a soft cloth to
prevent stain or salt residue from marring the glass surface.
Rinse the product with fresh water, after underwater use. Ensure that the product is
waterproofed before rinsing. Refer to [Maintenance and Storage] (P.E-19) for details.
Never use chemicals, cosmetics, any petroleum solvents such as paint thinner, or
neutral detergent on the product. They may deform and damage the product.
Do not leave the product in places with hot temperatures such as inside of a car or in
a car trunk in summer. The heat may deform plastic parts of the product, damaging
internal parts and resulting in potential fire or electric shock. If the product is sealed
tight in hot conditions, heated air expanding inside the product may deform the casing
and ruin the waterproofing.
Do not store the product in wet or high humidity place, to avoid mold, rust, corrosion
or malfunction.
Do not store the product with naphthalene or camphor mothballs, or in locations such
as a laboratory where chemicals are used. This environment can cause mold, rust,
corrosion or malfunction.
SEA&SEA SUNPAK Co., Ltd. assumes no liability for compensation of loss of

Carefully observe the O-ring maintenance manual for the handling of O-rings
before use.
The silicon grease included in the product package is inedible.

E-4
Precautions on Handling the O-ring
CAUTION
Are there any scratches or cracks in the O-ring?
Be careful about dust, sand, and hair
SEA&SEA products use blue O-rings. These O-rings are impregnated with
silicone oil through a special process. The lubricating effect of the O-ring lasts
as long as the silicone oil is gradually seeping out from within.
For the maintenance of these blue O-rings, make sure to use genuine SEA&SEA
silicone grease (O-ring grease for use with the blue O-rings that comes in tubes
with blue lettering and blue caps). If you use silicone grease from other companies
or SEA&SEA’s own silicone grease that comes in tubes with black lettering and
black caps, the grease you apply will be sucked into the blue O-rings due to
their special characteristics, which will result in insufficient grease. If this happens
even once, the O-ring will not revert to its normal state and must be replaced.
If the grease is insufficient, the O-ring will not slide, and it will become harder
to open and close the waterproof parts. Because of this, it could become
impossible to open or close the housing or it could cause flooding, so please
refrain from using the housing with insufficient grease.
Check the O-ring to make sure there are no
scratches or cracks. If there are, replace the
O-ring with a new one immediately. When
handling the O-ring, do not use pointed
metal objects, which could damage the
O-ring. Use of the included O-ring remover
is recommended.
Check the O-ring to make sure that there is no dust, sand, or hair on the O-ring,
in the O-ring’s grooves, or on the O-ring’s contact surfaces. If any of these things
are attached, remove them completely. If used as is, these things could cause
flooding.
This product is kept watertight by the O-ring. To keep the O-ring functioning
properly, please observe the following. Improper handling of the O-ring could
cause flooding.
O-ring remover

E-5
Silicone grease protects the O-ring from
chafing. After checking the O-ring to make
sure that there are no scratches, dust, or
debris, apply a light coating of silicone grease
to the entire O-ring with your finger. Applying
too much grease will make it easier for dust
and debris to adhere to the O-ring, and could
cause flooding.
When fitting the O-ring into the O-ring
groove, insert it straight into the groove; do
not bend or twist it.
Precautions on Handling the O-ring
Coat with silicone grease
Do not twist the O-ring
Remove the O-ring for inspection before each use
Be careful about how you store O-rings
O-rings last for one year
Although it depends on how well they are maintained, how often they are used,
and how they are stored, O-rings generally last for one year. It is advisable to
inspect them before use, and replace them early.
When storing spare O-rings or O-rings that you have removed from the housing,
keep them in a cool place out of direct sunlight. Also, when storing O-rings, do
not place heavy objects on them or twist them.
In principle, the O-ring should be removed before each use so that the O-ring,
O-ring groove, and O-ring contact surfaces can be checked. This is because you
cannot find any sand or debris that may have gotten into the O-ring groove if the
O-ring is not removed. For routine maintenance prior to each use, it is advisable
to make sure to remove the O-ring.

Maintenance and Storage
CAUTION
After rinsing, dry the product well with a soft dry cloth, then let the product dry
in the shade, out of direct sunlight.
Do not dry the product by heating (using a hair dryer, for example). Heating can
deform and damage the product.
If you will not use the product for an extended period of time, store it away from
high temperatures, high humidity, direct sunlight, or extreme cold.
Do not store the product with naphthalene or camphor mothballs, or in locations
such as a laboratory where chemicals are used. This environment can cause
mold, rust, corrosion or malfunction.
Always remove the camera from the housing after use. Thoroughly wipe off water
before opening the housing and avoid any water drops inside the housing.
After using the product, maintain the O-rings before storing. Examine the O-rings
before and after each dive. We recommend early exchange of the O-rings, at
least once a year.
Every two years we recommend a complete overhaul of O-rings regardless of
the frequency in use, for the best performance of the product.
After each use in salt water, make
sure it’s watertight, then soak it
sufficiently in fresh water.
Insufficient soaking causes damage
by salt to the product. Salty residue
may be left on the product where it will
crystallize as it evaporates. Crystallized
salt is hard to dissolve and difficult to be
removed once formed, and it will result in
water leakage.
Never use chemicals, cosmetics, any petroleum solvents such as paint thinner,
or neutral detergent on the product. They may deform and damage the product.
