Usage precautions

Never use any of the following chemicals for cleaning, rust-
proofing, fog prevention, repair, or other purposes.
1) Do not clean the marine case with alcohol, gasoline, paint
thinner, or other volatile organic solvents, chemical cleaners
or similar agents. (Pure water or lukewarm water is adequate
for cleaning.)
2) Do not use rust-proofing agents or the like on metal parts.
(Stainless steel and aluminum are used for all metal parts, so
pure water is adequate for cleaning.)
3) Do not use commercially-available anti-fogging agents.
(Always use the fogging agent that came with the marine
4) Do not use any silicon grease other than that specified for the
O-ring. (Always use the silicon grease that came with the
marine case.)
5) Do not use any adhesives for repairs, etc. (If any repairs are
necessary, please consult the store of purchase.)
Direct or indirect use (vaporized chemicals) of any of the
above chemicals on the marine case can cause cracks when
the marine case is placed under high pressure.
Exercise caution, as this marine case is a completely airtight
structure. If it is left exposed to direct sunlight, or in a car, ship,
or on the beach, the internal temperature can climb extremely
high, which may cause the camcorder inside to stop working
Do not use the glass cleaner or cleaner for any purpose other
than cleaning the front glass.
If the camcorder is sealed inside the marine case in an area
where the humidity and temperature are high, diving will make
the humidity trapped inside the marine case cool down, causing
condensation to form and the glass surface to become fogged. It
is recommended that you insert the camcorder into the marine
case in an area where the humidity is low and the temperature
is close to that of the water where you will be diving.
If a piece of aluminum foil is cut to approx. 50 cm
inserted into the glass part of the marine case, fog inside the
marine case will adhere to the aluminum foil, as its heat
conductivity is higher than that of glass. This is an effective way
to quickly reduce fog inside the marine case.
Do not open or close the case in areas where it may be
subjected to water spray or sand.
If you must open the marine case at the diving site in order to
replace the battery or tape, observe the precautions below.
1) Select a location safe from water spray and sand.
2) Completely wipe off any water between the main unit and
the lid section of the main case and on the buckles. Thor-
oughly dry off any water remaining on the marine case with a
dry cloth.
3) When removing the buckles and opening the lid section, be
careful that no water drips from your hair or body into the
marine case.
4) In order to avoid touching the camcorder with hands that
have salt water on them, place a towel dampened with pure
water in a plastic bag beforehand and use it to wipe any salt
off your hands and fingers before touching the camcorder.
Fit them to
attachment holes.
and is
Do not throw the marine case into the water.
After use, wash off adequately with pure water as soon as
possible. If the marine case has been used in salt water, soaking
the marine case in pure water for a while is an effective way to
remove salt.
Be sure to operate all levers and buttons to wash off any salt in
the grooves. If any salt remains, it will dry out and crystallize.
This could result in water leakage.
After washing, wipe off any water with a dry cloth free of salt to
completely dry off the marine case. However, do not expose the
marine case to direct sunlight in order to dry it. This can cause
discoloration and breakage of the marine case, and can speed
up deterioration of the O-ring.
Wipe the inside of the marine case with just a dry cloth.
Maintain the transparency of the front glass by wiping the inside
face with a silicon cloth or the like moistened with cleaner
If the front glass is left dirty, it may cause fogging.
Remove the O-ring from the lid section and wipe off any salt,
sand, and other foreign matter. In the same manner, wipe off
any adhering foreign matter from the groove into which the
O-ring was fit and from the main unit of the marine case where
the O-ring contacted it. When removing the O-ring from the
groove, avoid using sharp-tipped metal objects; instead use a
round-tipped object, such as a hair pin, to avoid damaging the
O-ring when you remove it.
Since the marine case is made of polycarbonate resin, handle it
carefully. In particular, it can be easily scratched by rocks, etc.
at the shooting site and may be damaged if it is dropped or
otherwise subject to shock. When going to the shooting site by
car, ship, train, or plane, avoid transporting the camcorder in
the marine case. If you take adequate handling precautions,
however, there should be no problem in transporting the
camcorder in the marine case for a short distance, for example
from the target site to the diving site.
Avoid removing any parts other than those indicated in the
user's manual, altering the marine case, or using any parts other
than those specified. If any problems occur, please consult the
store of purchase.
The appearance and specifications of this unit are subject to
