The rubber seal that lines the camera housing forms a waterproof barrier that
protects your HERO3 in wet and underwater conditions. Keep the camera housing's
rubber seal clean; a single hair or grain of sand can cause a leak.
After every use in salt water you will need to rinse the outside of the housing
with non-salt water and dry. Not doing this can eventually cause corrosion of
the hinge pin and salt buildup in the seal, which can cause failure.
To clean the seal, rinse in fresh water and shake dry (drying with a cloth may
cause lint to compromise the seal). Re-install the seal into the grooves in the
backdoor of the housing.
WArninG: Failure to follow these steps each time you use your HERO3 can
result in leaks that may damage or destroy your camera. Your warranty does not
cover water damage resulting from user error.
