MAINTENANCE
CAUTION! Allowing saltwater and contaminants to dry on housing can damage functions and
O-Rings possibly causing water leakage. Clean with fresh water only, using a soft, dry cloth
to wipe away water.
※ We recommend a complete Housing overhaul once every year.
1. After use in salt water, wash off salt and other contaminants by soaking empty Housing,
with Lens Port attached, thoroughly in a bucket of fresh water (lukewarm) for 10 to 20
minutes.
2. Manipulate all buttons and dials several times to flush out salt deposits and other
contaminants.
3. Wipe any water off Housing with a soft dry cloth.
4. Remove Lens Port and open Back Cover.
5. Using the O-Ring Removal Pick, remove O-Rings.
6. Clean O-Ring grooves and contact surfaces using a clean cotton swab. DO NOT clean
Housing or optional Lens Ports with volatile organic solvents or chemical cleaning agents
such as thinner, gasoline, and benzine, etc.
7. Perform O-RING GREASING & MAINTENANCE as instructed below before re-installing.
※ O-RING GREASING & MAINTENANCE ( 1)
※ Before conducting grease-up of the housing Back Cover and Port O-Rings, thoroughly
clean O-Ring grooves (cover and port), and O-Ring contact surfaces (cover and port). Be
sure to also apply a very thin layer of grease to contact surfaces.
1. Using the O-Ring Removal Pick, remove O-Rings.
2. Clean sand, salt, other contaminants and old grease from O-Rings.
3. Clean O-Ring grooves and O-Ring contact surfaces using a clean cotton swab.
4. Visually and physically check O-Ring by running it through finger tips, feeling for cuts,
cracks or any other defects that may cause leakage. Such defects will cause water
leakage, so be sure to replace the O-Ring. Be careful not to stretch or pull the O-Ring too
much.
5. Squeeze a rice grain sized bead of silicone grease on your thumb and forefinger. Taking
care not to pull or stretch the O-Rings too much, uniformly spread grease on O-Ring. Too
little grease may cause the O-Ring to twist in the groove, possibly causing water leakage.
6. Place O-Ring in O-Ring grooves, making sure that it is uniform, not twisted or bulging out,
possibly causing water leakage. When closing back cover, visually check O-Ring surface,
tracing a finger over it making sure no hair, lint or other contaminants are attached.
Important Notes:
※ When Housing is not used for long periods, remove O-Ring, place in a plastic bag to keep
them free of dust and other contaminants and store in a place out of direct sunlight.
Please also be careful of prolonged exposure to direct sunlight during use. The O-Rings
and Housing may become deformed, causing water leakage.
※ After extended periods of non-use, soak empty Housing, with Lens Port attached, in
lukewarm for half a day. Manipulate all buttons and dials several times. Using a soft, dry
cloth wipe away water.

CAUTION!
※ The O-Rings are an essential part of waterproofing for this housing. Not properly greasing
the O-Rings as direct may cause the O-Rings to twist in the O-Ring grooves, possibly
causing water leakage.
※ Always perform the above O-Ring, O-Ring groove and O-Ring surface maintenance and
greasing every time you open/close the housing.
※ Please pay close attention and make sure the O-Rings are not twisted or bulging, free of
any contaminants (dirt, hair, etc.), and that foreign objects do not obstruct proper closing
of the Housing back cover or attachment of the Lens Port.
※ DO NOT clean the Housing with volatile organic solvents or chemical cleaning agents
such as thinner, gasoline, and benzine, etc.
※ Housing Monitor is manufactured using hard coat acrylic. When cleaning use a clean soft
cloth taking care not to scratch it.
