CAMERA HOUSING
PREVENTING WATER DAMAGE TO YOUR CAMERA
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 and damage your camera.
After every use in salt water, rinse the outside of the camera 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 camera 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.
