Before use, this unit must be pre-tested to check if there is any water leakage.

This marine case is a precision instrument designed to permit safe video recording under high water pressure. Please pay careful attention when handling the unit before and after use, as explained in this user’s manual. Each part of the marine case has been subject to strict controls during the manufacturing process, and the individual functions have faced stringent tests during the assembly process. Each marine case has also had to pass water-proof inspections using highpressure water testers. However, damage can sometimes occur during transport and distribution, or during storage after purchase, so before diving always carry out the following pre-use test to verify safety.

Pre-use test

Be sure to perform the following pre-use test before diving.

1. Before mounting the camcorder inside the marine case, dive with only the empty marine case and test for water leaks.

•You can easily check for water leaks at a depth of 1 m, where

there is no water pressure. Be sure to perform this test to ensure the safety of your camcorder.

2. The following are some common causes of water leaks: A. The marine case is used without attaching the O-ring. B. The O-ring is not mounted in the correct position. C. The O-ring is damaged or deformed. D. There is sand, dirt, hair or other foreign matter on the O-ring. E. There is sand, dirt, hair or other foreign matter on the contact

surface of the O-ring or on the inside of the lid.

F. The provided strap or silica gel bag is pinched inside the

marine case when the lid is closed. To protect your camcorder and ensure optimum use, keep the examples listed above in mind when using the marine case.

JVC accepts no responsibility for water leakage or damage to anything inside the marine case (camcorder, cassette, etc.) due to careless usage of this product. Be sure to follow correct procedures when using the marine case.

Marine Case

Mounting method and operating method for each part

1 Tighten the camcorder’s grip strap. 2 Remove the four buckles on the marine

case and open the front lid.

3 Align the Power Lever with the “OFF”

mark on the marine case.

4 Set the camcorder’s Power Switch to

“OFF”, then open the LCD monitor and insert the camera into the marine case. Place the included anti-fogging silica gel in the gap between the camcorder and the marine case to prevent fogging in the marine case.

• When inserting the camera, make sure that the position of the grip pad’s metal part is straight.

• If the camcorder’s Operation Switch is set to “ settings as required then insert the camcorder into the marine case.

5 Fit the Zoom Lever projection on the

marine case over the outer groove of the Power Zoom Lever on the camcorder, making sure that it is securely fit.

If the camcorder’s Power Switch is not set properly when the camcorder is placed in the marine case, it could break and/or it could damage the Power Lever aligning boss on the marine case.

6 Before sealing the marine case, check that

there is no sand, dirt, or other foreign matter on the O-ring mounted on the front lid or on the O-ring contact surface on the main unit. Also make sure that the inserted silica gel bag is not pinched. If you dive with foreign matter trapped in these areas, water will leak.

7 Check that the O-ring on the front lid is

correctly mounted in the groove, then press in the front lid. Flip down the four buckles in the directions indicated by the arrows in the figure on the right to seal the marine case.

8 Turn the marine case’s Power Lever in the

direction of the arrow to set the camcorder’s Power Switch to “

Usage precautions

1 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 case.)

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.

2 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 properly.

3 Do not use the glass cleaner or cleaner for any purpose other

than cleaning the front glass.

4 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.

5 Do not open or close the case in areas where it may be

subjected to water spray or sand.

6 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. Thoroughly 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.

and is

7 Do not throw the marine case into the water. 8 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.

9 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.

0 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 agent.

! 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.
