User’s Manual ENGLISH
Names of the parts
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.

Mounting method and operating method
for each part
1. Remove the two buckles on the marine case and open
the front lid.
2. Remove the camcorder hand strap or grip strap.
3. Set the marine case’s Power Dial so
that it fits in the indentation on the
marine case (the “Off” position).
4. Set the camcorder’s Power Dial to
“OFF”, then pull out the viewfinder
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.
5. Fit the underside of the marine
case’s Power Dial around the
camcorder’s Power Dial. Confirm
that the marine case’s Power Dial is
in the correct position.
If the camcorder’s Power Dial is
set to the wrong position, the
underside of the marine case’s
Power Dial may be damaged and no longer turn properly.
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 two 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 Dial in
the direction of the arrow to set the
camcorder’s Power Dial to “

at the center of the Power Dial. To
stop recording, press the button
again.
10. The zoom can be adjusted with the
Zoom Lever.

switch the camcorder power dial
to the Off position.
