Battery Door Instructions:
There is a rubber thimble provided to help open the Surf Camera’s battery door as it can be difficult to open (as it should be).
After each ocean use, rinse the camera with fresh water. When dry open the battery door and slide it back and forth to work out any salt grind trapped inside. When you close the battery door work the door lock side to side until the spring-load snaps back on its own.
The metal door slide just inside the battery door may need a drop of WD40 from time to time. To do this place a drop of WD40 onto a Q-tip and coat the metal part of the door slide near the hinge. Be careful not to get any on the rubber door seal.
Make sure there is no dust, sand, oils or water inside the rubber door seal. It is VERY important to make sure the door, rubber seal, and battery compartment are squeaky clean!!!
