Let the camera fully air dry before you detach the lens or open the battery door or media card
door.
Let the camera with lens still attached fully dry in a shady spot.
Carefully open the connector and battery compartment/media card slot door and use a soft cloth
to fully dry any water that may have made its way inside.
After confirming that no more water remains on the exterior of the Nikon 1 AW1
and its attached waterproof lens, slowly open the connector and battery
chamber/media card slot covers and remove any water, sand or other foreign
matter using a soft, dry cloth.
