VI. After using the housing underwater
Follow these important steps after each underwater use:
1. Soak the sealed housing in fresh water for about 20 minutes. Push each button 20 times to flush out any
saltwater, sand or dirt trapped under the buttons.
2. Towel-dry the housing. Make sure that you and the waterproof housing are completely dry before opening
the vacuum check port cap and waterproof door.
3. Release the internal vacuum pressure before opening the housing. Unscrew the vacuum check port cap
and use your fingertip to move the yellow rubber one-way valve sideways to release vacuum pressure. You
and the check port valve must be completely dry when releasing pressure or water will enter the housing!
4. Open the housing upside down with lens facing up to prevent water drops around the O-ring sealing areas
from entering the housing. Quickly dry any water drops that accidentally enter the housing.
5. The leak alarm may activate (beep) when opening the waterproof door. Power Off the housing to turn off
the leak alarm.
6. Follow the other care and maintenance instructions on page 49.
