2. Manipulate all buttons 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.

6. Clean O-ring grooves and contact surfaces using a clean cotton swab. DO NOT clean
housing or Lens Port with volatile organic solvents or chemical cleaning agents such as

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.
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 your 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 the 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. When closing back cover, visually check O-ring Contact
Surface, tracing a finger over it to making sure no hair, lint or other contaminants are
attached.
IMPORTANT NOTES:
※
When housing is not used for long periods, remove O-ring and place in separate plastic
bags to keep it 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-ring and housing may become deformed, causing water leakage.
※
After extended periods of non-use, soak closed empty housing in lukewarm for half a day.
Manipulate all buttons and dials several times. Using a soft, dry cloth wipe away water.
CAUTION!
※
The O-ring is an essential part of waterproofing for this housing. Not properly greasing the
O-ring as directed may cause the O-ring to twist in the O-ring groove, possibly causing
water leakage.
