MAINTENANCE
CAUTION! Allowing saltwater and contaminants to dry on housing can damage functions and
O-ring possibly causing water leakage. Clean with fresh water only, using a soft, dry cloth to
wipe away water.
※
A complete housing overhaul is recommended at least once every year.
1. After use in salt water, wash off salt and other contaminants by soaking empty housing
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. Open Back Cover.
5. Using the O-ring Removal Pick, remove O-ring.
6. Clean O-ring groove and contact surface using a clean cotton swab. DO NOT clean
housing or Lens Port 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)
※
CAUTION! This housing uses one (1) O-ring. Please be sure to install O-ring as shown
below. Failure to do so will result in water leakage.
1. Using the O-ring Removal Pick, remove O-ring.
2. Clean sand, salt, other contaminants and old grease from O-ring.
3. Clean O-ring Groove and O-ring Contact Surface using a clean cotton swab and/or cloth.
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 between thumb and forefinger. Taking
care not to pull or stretch the O-ring too much, uniformly spread grease on O-ring. Too
little grease may cause O-ring to twist in the groove, possibly causing water leakage.
6. Place O-ring in the O-ring groove, making sure it is uniform, not twisted or bulging out,
possibly causing water leakage.
7. Lightly grease Contact Surface.
8. Before closing back cover, visually check O-ring and O-ring Contact Surface to making
sure no hair, lint or other contaminants are present.
IMPORTANT NOTES:
※
When housing is not used for long periods, remove O-ring and place in a plastic
bags to keep it free of dust and other contaminants and store ina place out of direct
sunlight. Please also be careful of prolonged exposure to direct sunlight during use.
