opened between dives, to recharge the batteries. Before opening, make sure the outside of the housing is
thoroughly toweled dry. After removing the lid and servicing the flash, replace the lid straight away rather
than leaving it lying around. Before replacing the lid, make sure that no contamination such as dust, hair, salt,
etc. has fallen onto the gasket or its recess.
Procedure for Gasket Maintenance:
1.
Place the lid on a firm non-slip level surface.
2.
The gasket can be extracted using a gasket extractor tool (make sure the tool has no
sharp edges). Alternatively use the flat surface of your thumbs to gently stretch the
gasket on two faces [see figure below] thus making a small loop protruding a few mm.
The loop can then be grasped between finger and thumb, to pull the gasket over the lip.
3.
Clean the seal recess (the square groove where the gasket sits) with a cotton bud.
4.
Inspect the gasket all the way round its surface for damage such as cuts, tears or
contamination. This should be done visually and also by feeling the surface texture
between finger and thumb.
5.
IF THE GASKET IS DAMAGED OR SUSPECTED OF BEING DAMAGED,
DISCARD IT IMMEDIATELY. A spare gasket is supplied with your housing, or a
replacement gasket can be obtained from Fantasea. If the gasket is contaminated or
suspected of being contaminated, clean it with a cotton cloth that is free of all
chemicals or contamination. After cleaning inspect the gasket again.
6.
Replace the gasket into the groove; run a finger round the gasket to make sure it is
snugly seated in the groove.
