Note On The O-Ring - Sony MPK-DVF3 Mode D'emploi

Note 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.
Check the O-ring
Before using the marine pack each time, check that there are no scratches or cracks on
the O-ring and prevent dust from collection on it as it could allow water to leak in.
• Remove the O-ring from the groove with your finger. Do not use a metal tool or a
tool with a sharp point.
• Put the O-ring in the groove evenly. Never twist it.
• Check that there are no cracks or dust on the O-ring, then coat it slightly with the
supplied grease using your finger. This will prevent wear.
• While applying the grease, recheck for cracks or dust. Never use cloth or paper to
apply grease because the fibers may cling.
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 it completely, or the O-
ring and the surface of the marine pack may be damaged and water may leak in.
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 the
front and rear shells. If this happens, not only will the O-ring be damaged, but water
may leak in.
Useful life of the O-ring
Depending upon the maintenance and the length of use, we recommend changing the
O-ring every one or two years.
The O-ring (3-977-362-01) can be replaced at your nearest Sony Service Center.
When you store the O-ring
Store a reserve O-ring in its package in a cool dry place. Do not store in very hot, cold,
or humid place. Be careful not to crimp it or to place any heavy weight on it.
