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 rear 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.
