Maintenance
After recording in a location with a sea breeze, wash the camera thoroughly in fresh water with the
buckle fastened to remove salt and sand, then wipe with a soft dry cloth. It is recommended that
you submerge the Underwater Housing in fresh water for about 30 minutes. If it is left with salt on
it, metal portions may be damaged or rust may form and cause water leakage.
If sun oil is on the Underwater Housing, be sure to wash it off thoroughly using lukewarm water.
Wipe the inside of the Underwater Housing with a soft dry cloth. Do not wash it with water.
Be sure to perform the above maintenance each time you use the Underwater Housing. Do not use
any type of solvent such as alcohol, benzine or thinner for cleaning, as this might damage the surface
finish of the Underwater Housing.
When storing the Underwater Housing
To prevent deterioration of the waterproof packing, store the Underwater Housing in a cool, well-
ventilated location. Do not fasten the buckle.
Prevent dust from collecting on the waterproof packing.
Avoid storing the Underwater Housing in a cold, very hot or humid place, or together with
naphthalene or camphor, as these conditions might damage the Underwater Housing.
