Notes on the O-ring
The O-ring assures the waterproof function of the marine
pack. To maintain waterproof integrity, use it correctly.
Incorrect handling may cause water to leak in.
O-ring
Front shell
Check that there are no scratches or cracks.
Scratches or cracks on the O-ring may cause water to leak in.
If the O-ring is damaged in this way, replace it with a new
one. Do not remove the O-ring from the groove with a metal
tool or a tool with a sharp point.
Scratches
Crack
Remove any dust, sand or hair from the
O-ring.
Make sure there is no dust, sand or hair on the O-ring, in the
groove, or on the surface of the marine pack where
the O-ring touches. If there is, clean them completely, or the
O-ring and the surface of the marine pack may be damaged
and water may leak in.

Grease the O-ring
The grease protects the O-ring from wear.
Check that there are no cracks or dust on the O-ring, then
grease it using your finger. While greasing, double check
that there are no cracks or dust.
Never use cloth or paper to apply grease because the fibers
may cling.
Do not use any type of grease other then the supplied one,
or it may damage the O-ring.
If you run out of silicone grease (2-115-921-01) you can
purchase it from your nearest Sony Service Center.
Do not twist the O-ring.
Put the O-ring in the groove evenly. Never twist it.
Not this way
Do not pinch the O-ring with the marine
pack.
When joining the front and rear shells, take care not to pinch
the O-ring between them. If this happens, not only will the
O-ring be damaged, but water may leak in.
Storage
Put the supplied spare O-rings in the original carton and
store it in a cool place.
• Do not expose the O-ring to direct sunlight.
• Do not place a heavy object on the O-ring.
• Do not fold the O-ring.
Useful life of the O-ring.
Depending upon maintenance and the length of use, we
recommend changing the O-ring every one or two years.
The O-ring (3-952-928-01) can be replaced at your nearest
Sony Service Center.
