De not trap the O-ring with the marine pack. —
When jointing the front and rear shells, take care not to trap
the O-ring between the front and rear shells. If this happens,
not only will the O-ring be damaged, but also water may leak
in.

store it in a cool place.

It depends upon the maintenance and the length of use, but
we recommend changing it every one or two years. Use the
Sony ACC-810M marine pack maintenance kit (not supplied)
to replace.
