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. Tighten the camcorder’s grip strap.
2. Remove the four buckles on the marine case and open the
front lid.
3. Align the mark on the Power Dial
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.
• Set the camcorder’s MODE Dial to the desired setting.
• 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 Dial 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.

Snapshot recording. If the flash is used,
its brightness will be darker than usual
due to the marine case. This is normal
and is not a malfunction.
• When recording in the PS-WIDE
mode, a shadow (eclipse) may
appear around recorded images.
10. The zoom can be adjusted with the
Zoom Lever.
11. When you are finished shooting, set
the marine case’s Power Dial to
“OFF” (in the direction of the arrow)
while pressing it down to set the
camcorder’s Power Switch to “OFF”.
• The camcorder’s Power Lamp goes
