3. Fasteners that are removable should occasionally have the threads lubricated with silicon grease.
4. Rinse clean and remove water spots from external filters and lens surface after every dive or water spots may build up
and become impossible to remove. Dry gently with a soft, lint-free cloth.

SERVICING O-RINGS
1. O-rings and sealing surface should be lightly lubricated with silicon lubricant on a regular basis. This is not necessary
after every dive; every tenth dive during regular heavy use is sufficient. This should always be done before storing the
housing and before a first dive after taking the housing out of storage.

2. It is important never to use a sharp instrument when removing an o-ring as this may cause damage to the o-ring or the
o-ring groove. A hairpin or a credit card works well.

3. The removed o-ring should be examined for damage. Check to make sure that the o-ring is free from nicks and cuts
and that it retains its original round profile. O-rings that appear to be damaged should be discarded immediately and
replaced with new o-rings.

6. Wipe the part of the housing that the o-ring seals against with a clean lint free cloth.
7. Re-grease the o-rings with a thin layer of silicon grease until it appears to be smooth and shiny. Do not over grease it -
use just enough grease so that the o-ring will pull smoothly through your fingers. Excessive amounts will only attract dirt to
the o-ring.
