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.

It
is
recommended
that
you
ship
the
housing
to
our
distributor
for
a
complete
overhaul
every
year
or
after
every
200
dives.
