Handling the O-ring (continued)
Final check
Check the O-ring again for any dirt, cracks or twisting, etc.
How to check for water leakage
Before installing the equipment, always close the marine pack and
immerse it in water to a depth of about 15 cm for about three minutes to
make sure no water leaks in.
P CAUTION
After taking photos near a sandy sea bottom or placing the camera on the
sand, remove the O-ring and inspect it.
Be sure to take a spare O-ring with you.
You can replace the fitted O-ring on location if
something goes wrong with it.
O-ring life
Replace each O-ring with a new one after one year of use.
Even if the O-ring is not cracked or scratched, deformation or wear
reduces its waterproof qualities.
