1. Soak the housing system in fresh water after each salt water use, during which all
control buttons/knobs should be operated a few times to avoid the accumulation of
salt residue; wipe the housing with a towel before opening.
2. After each day of diving, it is advisable to have the main O-ring in the front part of
the housing removed from its groove with the O-ring remover and inspected for
damage. Also check that the O-ring retains its original circular shape; never
stretch the O-ring excessively or remove it with a sharp object. The O-ring groove
should be cleaned to ensure it is free from any salt deposit or foreign material;
lightly coat the O-ring with the provided lubricant before reinstalling it in the
groove. A damaged O-ring should be discarded immediately and replaced only
with one that is provided by NAUTICAM.
3. Replace the main O-ring annually.
4. It is recommended that you ship the housing to our distributor for a complete
overhaul every year or after every 200 dives.
