■Preparation before setting

Charge the battery and set the recording medium in the digital camera.

■Set in housing

If only a small amount of dust or hair be attached to the O-ring of the housing, the housing's airtightness will be lost and it will submerge.
Be careful when opening and closing the housing or setting the camera in the housing.

Because digital cameras generate heat, high humidity inside the housing can cause the camera lens to fog.
Put a small silica gel in the housing when setting up the digital camera.

After setting, let's do a flood test.
Let's soak it in tap water for about 30 seconds and check that there are no air bubbles from the joint of the housing and the buttons can be operated.
