I have had a number of Sealife systems and we use them in our rental line. If you are saving the photos to a card you may check the card prior to sending it back. If it does require return I think that Sealife will be glad to repair or replace and get you back underwater with one that is correct. Call them they are great to work with or better if you purchased this at your LDS then stop in and have one of their instructors check it out. May be something simple.
Hope this helps!
