Apply a coating of grease to the O-ring.

•Apply a small drop of grease onto the O-ring and evenly coat the entire surface of

the O-ring with the end of your finger.

•Do not use paper or cloth as fibre may stick to the O-ring.
•Make sure that a thin coating of grease is applied to the surface of the O-ring at all

times. Grease protects the O-ring, and prevents wear.

•After you have applied a small drop of grease onto the O-ring, set the O-ring

immediately. Do not leave the greased O-ring on a desk or other surfaces.

Place the O-ring in the groove on the marine pack.

Place the O-ring evenly in its groove paying attention to the following points:
– Is there any dirt on the O-ring?
– Is the O-ring twisted?
– Do not pull the O-ring.
– Is the O-ring protruding?

After you have fitted in the O-ring, check it again for the following:
– Is the O-ring twisted?
– Is there any dirt on the O-ring?
– Is the O-ring protruding?
– Are there any cracking or distortion on the O-ring?

After you have replaced the O-ring, close the marine pack before you insert the
equipment you are using. Immerse the marine pack for about three minutes in water to
a depth of about 15 cm, and check for water leaks.

P

When you have taken photos on a sandy sea bottom or have placed the camera on the
sand, remove the O-ring and check for water leaks.

Bad example

Good example

• After you have used the marine pack, be sure to perform the following:

– Wash the marine pack with fresh water with the buckle closed to remove salt or

sand.

– Insert the marine pack in fresh water for about 30 minutes with the buckle closed.

If salt is left on the marine pack, metal parts and the O-ring might be damaged, and
cause water leaks.

– When sun oil is stuck to the marine pack, wash off with lukewarm water.

If sun oil is left on the marine pack, the surface of the marine pack might become
discoloured or become damaged.

– Wipe the inside of the marine pack with a soft, dry cloth. Do not wash with water.

• Remove the O-ring each time that you have finished using it, and check it.

If the marine pack is dried with sea water still in the O-ring groove, salt crystals form,
and might impair the O-ring's functions.

• Do not use thinner, benzene, alcohol or other solvents as they will damage the

surface finish.

• Prevent dust from sticking to O-rings.
• Apply a thin coating of grease to the O-ring, set it in the groove, and store in a well-

ventilated location. Do not close the buckle.

• Avoid storing O-rings in hot, cold or humid locations, and placing in naphthalene or

camphor. These locations and solutions will damage the materials.

• To maintain the O-ring's functions, avoid storing them in hot locations or in the direct

sunlight.

• Do not place the spare O-ring under heavy objects. Doing so might deform the

O-ring.

Replace the O-ring with a new one after one year of use.
Even if the O-ring is not cracked or scratched, deformation or wear reduces the
waterproof qualities of the O-ring. Replace the O-ring with a new one if cracking, skew,
distortion, fine splitting, scratches, sand-biting, etc. is found.

Contact your nearest Sony Service Center.

The metal parts will rust and the movement of the operation switches will be impaired
if you leave salt water on the marine pack. If sea water enters through scratches in the
coating, the salt can corrode the metal parts of the marine pack unit and cause the
coating to peel off. After recording in the sea, submerge the marine pack in tap water or
fresh water for about 30 minutes before undoing the buckles to completely remove any
salt from the marine pack unit, filter, and wide-conversion lens.
After washing, wipe any water from the inside of the marine pack and the loaded video
camcorder with a soft dry cloth.
*  Always follow the above precautions when you use the marine pack.
When you open the marine pack or exchange the battery pack of the grip, take care that
no water drips from your wet suit or hair.
Do not leave the marine pack under direct sunlight for a long period of time, otherwise
the temperature in the marine pack may rise and the equipment inside may be
damaged. If you cannot avoid leaving the marine pack under direct sunlight, be sure to
cover the marine pack with a towel or other protection.

Coat the O-ring slightly with the supplied grease, and put it in the groove correctly.
Join the front and rear shells then put it in a cool and dry place without fastening the
buckles.
Avoid storing the marine pack in a very hot, cold, or humid place, or together with
naphthalene or camphor, as these conditions might damage the unit.

When transporting the marine pack, be sure to remove your camcorder from it.
Otherwise this might damage the unit.

Note
When you use the supplied carrying
bag, attach the supplied carrying belt
and adjust the length of the belt.
Avoid rough handling or a shock. We
recommend covering the marine pack
with a towel or other protection.
