INTRODUCTION Inspecting the Cover O-rings The battery cover and terminal cover are fitted with rubber gaskets called "O-rings" that keep water from entering the camera. Even very fine pieces of foreign matter (a single hair, a single grain of sand, etc.) on an O-ring can result in incomplete sealing and allow water to leak inside. Note that water leaking inside the camera results in unrepairable damage. Make sure you periodically inspect the O-rings, O-ring grooves, and contact surfaces for cracks, deformation, dirt, and dust. Use a soft, dry cloth to wipe all dirt and dust from the O-rings and their contact surfaces.

Use a cotton swab moistened with water to wipe dirt from the O-ring groove and contact surface. • Wash the O-ring in water, dry it off, and then replace it into the O-ring groove. • Make sure the O-ring enters the groove securely, as far as it will go. IMPORTANT! • Never pull on an O-ring with excessive force or try to expand an O-ring. • Never apply grease or oil to an O-ring. • Never use a pointed object to remove an O-ring. Do- ing so can damage the O-ring and lead to leaking. • Excessive twisting of an O-ring can cause leaking. Al- ways handle O-rings with care. • Have an O-ring replaced whenever it becomes cut, damaged, or deformed. You should also have O-rings replaced every two years, regardless of their condition. Take your camera to your nearest CASIO maintenance service provider to have O-rings replaced. Note that you will be charged for O-ring replacement. If you frequently use your camera where it is exposed to water, sand, or dust, we recommend that you have the O-rings replaced once a year. 16
