Maintenance on the marine case

Always perform maintenance on the marine case after you have finished recording.

Salt crystal or dirt will accumulate inside the marine case if maintenance is not performed, and this can cause water leakage.

Caution

zThe camera may fall out if the buckles are opened with the front glass facing down.

zIf you cannot avoid opening the marine case at the diving location, pay attention not to let water droplets from your hair or your body enter the case.

Wash the marine case in water while it is still sealed

zDo this within 30 minutes after diving.

zPour in fresh water until the marine case is completely submerged in the container, and shake the marine case in the upward, downward, left and right directions.

zMove the buttons and levers while the marine

case is submerged, and rinse the dirt out from any gaps or grooves. Proceed to C

zIf used in the sea

-> Proceed to Aerforming salt removal

Performing salt removal

If the marine case was used in the sea, submerge the marine case in fresh water for at least 1 hour to remove salt.

APrepare a container that contains fresh water that is five times more than the volume of the marine case.

z The container must be big enough to allow the marine case to submerge fully.

z If only small containers are available, pour in fresh water that is equivalent to at least five times the volume of the marine case over a few times.

z Shaking the marine case in the upward, downward, left and right directions will be more effective.

z Move the buttons and levers while the marine case is submerged, and rinse the salt out from any gaps or grooves etc.

z Make sure the grip is also free of salt.

BPut in fresh water for at least 1 hour.

CRemove the marine case and wipe off water droplets on the case surface using a dry towel.

DRemove the camera.

z Face the front glass of the marine case upwards, and open the buckles to remove the camera, while paying attention not to let water droplets at O-ring or buckles enter the case.

ERemove the O-ring, and wipe off salt, sand and other foreign matter.

z Also wipe the groove in which the O-ring was inserted, and the part of the marine case that was in contact with the O-ring, and allow them to dry.

¹For details on handling and storing the O-ring, refer to the “O-ring Maintenance Manual”.

Dirt, sand, salt crystals, etc.

Hair, lint, etc.

FWipe the inside and outside of the marine case with a dry cloth.

¹Use a lint-free cloth to wipe the inside of the marine case.
