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

Please read before use.

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 high-
pressure 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.

  • Page 2: Usage Precautions

    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.
