In order to use this product safely
Preparation (APg. 16)
• Check that there is no dirt, cracks, or damage to
the O-ring.
• Always apply grease to the O-ring.
Attaching the Marine Case to the Camera
(APg. 17, 18)
• Attach the power button cap depending on the
camera used.
• Make sure that the O-ring is not twisted, and that
you do not forget to attach it.
• When tightening the seal, make sure there are
no foreign objects caught in the seal.
Recording the Video/Still Image Files
(APg. 18, 19)
• Avoid opening and closing the marine case in
the shooting location.
• When holding the marine case, lower it gently
into the water.
Detaching the Marine Case/Maintenance
(APg. 19, 20, 21)
• Always wash the marine case in fresh water
after use.
• Perform maintenance on the O-ring.
If water leaks into the case due to careless use of
the marine case, JVC cannot accept responsibility
for any damage that may occur to the internal
equipment and materials (video camera, SD card,
etc.), or any expenses incurred in taking the
photographs/video. Therefore, please be careful
when using the marine case.
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 waterproof 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 camera inside the
marine case, dive with only the empty
marine case and test for water leaks.
Allow 5 or 6 minutes to ensure there are no
leaks.
Be sure to perform this test to ensure the
safety of your camera.
2. The following are some common causes of
water leaks:
Safety Precaution
Please read before use
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 drying agent bag is
pinched inside the marine case when the lid
is closed.

3. Check that there are no scratches or cracks
on the marine case every time you use it.
The marine case must withstand water
pressure with use. Repeated exposure to
pressure eventually leads to material fatigue,
which may result in damage of the marine
case. Every time you use the marine case,
check in advance that there are no scratches
or cracks. If you frequently use the marine
case, be sure to ask for maintenance at the
store of purchase. (There is a charge for
maintenance.)
To protect your camera 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
(camera, SD card, etc.) due to careless usage of
this product. Be sure to follow correct procedures
when using the marine case.

O リングについて 日本語
LYT2232-002A

●O-ring is a type of seal used to make underwater
cameras, strobes and other diving instruments,
waterproof.
It looks like a big, thick rubber band.
●The O-ring is an important component that protects the
camera from water by keeping the marine case airtight.
●As a general rule, each time before using
(Salt crystals are for med when seawater th at entered the O-rin g groove dr ies.
Salt crystals just like sand, can cause water leakage.)
●When shooting on the sandy seabed, or when the camera is placed on the
sand
●When not used for a long period of time
●Remove the O-ring
¹To inspect the O-ring, use the pick supplied to remove it from the O-ring groove.
¹Do not use knifes, scissors, tweezers, and other sharp objects which might damage the
O-ring and the O-ring groove.

●Check for hair, dirt, sand, salt, dust, and other foreign matter
¹Even small foreign matter can cause water leakage.
●Check for foreign matter that are not visible by rubbing gently with your
fingers
¹Be sure to remove all foreign matter.
●Wipe off any residual grease
Wipe off gently with a soft cloth or tissue paper.
¹After wiping, make sure the fiber of the cloth or tissue paper is not adhered to the
O-ring.
●Check for any deforms (distorted, crushed), cracks or cuts on the surface
Cracks on the O-ring can be easily spotted by bending and
twisting it gently.
¹Never use an O-ring if it is deformed, cracked, or
damaged in any way. It can cause water leakage.
¹Replace the O-ring with a brand new one every year.
Even if there are no nicks, cracks, etc., its effectiveness
will deteriorate due to wear.

●Apply silicone grease on the O-ring
The O-ring needs to be re-greased when its surface appears dry.
Be sure to remove the O-ring and apply the silicone grease on it.
ASqueeze about 1 cm onto your finger
BApply it on the O-ring by holding the O-ring with your fingers.
If the amount applied is not enough, repeat the above step.
¹Make sure that you do not apply too much grease!
Dirt and dust will easily adhere if too much grease is applied.
Neither will it improve the waterproofing. Be sure to apply moderately.
¹Do not pull too strongly!
This will cause deformation.
●Check for any foreign matter in the O-ring groove
Inspect thoroughly as it is usually not visible.
Grains of sand and crystallize salt may be stuck inside.
Remove them carefully by either using an air spray or a swab.
¹Make sure the fibers of the swab are not adhered.

●Insert the O-ring after inspection
Make sure no foreign matter is adhered when placing the greased O-ring back to the
groove.
Do not pull too strongly, and make sure the O-ring is placed evenly and not twisted.
<POINT>
Insert from the four diagonal corners
and smooth out evenly.
●If you do not intend to use the marine case for a long period of time,
remove the O-ring and allow it to rest.
ARemove the O-ring.
¹Be sure to use the pick supplied.
BWipe off the grease gently.
CCheck for any foreign matter that might be adhered to it.
DPut the O-ring inside a clean plastic bag, and store in a way that it will not be subject to
stress.
¹Do not put in moth balls and other insect repellents.
Storing the O-ring
¹Do not leave the O-ring as-is in the marine case for a long period of time.
It may deform due to heat and pressure resulting from the locked and tightened state.
¹Do not store in hot and humid locations.
This will cause the O-ring to deteriorate more quickly.
