IV. Setting up the housing
1. To open the housing, push and hold release button (A) and rotate cam-lock (B) counter-clockwise.
Important: Release the internal vacuum pressure before opening the housing. To release the vacuum
pressure, unscrew the vacuum check port cap and use your fingertip to move the yellow rubber one-way valve
sideways. You will hear pressure releasing.
After diving, make sure you and the housing are completely dry before releasing pressure and opening
the housing. If the valve area or your finger is not dry, water drops will be forced into the housing
when releasing pressure. Open the housing upside down, with lens facing up, to prevent water drops
trapped around the sealing area from accidentally entering the housing.
