MUST DO for underwater housing:
1. Read these instructions before using the underwater housing.
2. Do not exceed the depth rating printed on the lens port of the housing.
3. Keep main O-Ring perfectly clean.
• Clean main O-ring with cleaning brush provided before every use. Do not
remove O-ring. Do not grease O-Ring.
• Store camera and housing only after careful cleaning and when totally dry.
• Housing uses one large O-ring at housing sealing lid. Never use housing
without O-ring in place.
• If O-ring is damaged, contact the SeaLife Service Center. (See page 58).
Do not continue using housing
• O-ring must be perfectly clean (no sand, dirt or debris) before sealing
housing.
• Soak or rinse sealed housing with fresh water after use in salt water.
4. Carefully close lid to seal housing.
• Make sure O-ring does not slip out of the groove when sealing.
• Press lid firmly and tightly down into housing to ensure a waterproof seal.
5. Never let any moisture or dirt get inside housing when opening.
• Only open and load the housing in dry cool air, such as inside an
air-conditioned room.
6. For great underwater pictures you need:
• Clear water conditions, control your buoyancy before taking picture, get
as close as possible to subject (ideal distance is 2’ to 6’).
• Use the SeaLife Macro Lenses/Filter for close-up pictures inside of 3.5’
with super details and vibrant colors. Minimum shooting distance without
any macro lenses is 3.5 feet (107cm).
• Use SeaLife External Flash to enhance colors and reduce backscatter.
7. Store housing at room temperature in a clean and dry place
• Do not expose housing to direct sunlight for prolonged periods of time.
• Do not store housing in hot locations, like the trunk of your car.
