The internal vacuum pressure must be released before the housing can be opened. Unscrew the vacuum check valve cap. Use your fingertip to move the rubber yellow 1-way valve sideways to release the pressure. Do not push down the valve as that will not release the pressure. You may also use some unsharp object, like a pen cap, to move the valve sideways. Never use sharp object near the rubber 1-way valve.
The housing wrist strap included with the SportDiver UW camera attaches to the housing as shown below. Attached the looped end of nylon cord through the housing strap connector (A). The clip (B) is used for attaching the camera to your BCD (buoyancy Control Device) D-ring. Adjust the sliding lock (C) to tighten around your wrist.
Humid air or water drops trapped inside the underwater housing may condense on the cooler glass lens port and cause fogging. Here is the best way to prevent fogging:
Glare in the upper left corner may occur when a bright light or sunlight is behind you and there is an air gap above the phone. Light is passing through the air gap and reflecting of the inside of the glass lens port. It is more likely to occur on land and not underwater. To prevent this glare, apply a small piece of black tape to the inside of the housing to fill the air gap.
The volume button is being pressed accidentally. Move the rubber grip tabs around so they do not touch the iPhone buttons. Refer to page 14 of the manual.
Your finger is conductive like water, so touching the water sensor will activate the alarm. Avoid touching the water sensor. If the alarm goes off by accident, power the housing off and on again. Refer to page 21 of the manual.
Back tap is a new feature with iOS 14 that performs select tasks when tapping the back of the phone 2 or 3 times. Back Tap should be turned Off when the phone is inside the housing because it may accidently perform the task and close the SportDiver app if the housing gets bumped or knocked.
We recommend using the VLC Media Player, which is a free download at https://www.videolan.org/vlc/index.html
The lens setting has a 1-second delay when changing lenses. That is necessary for stable app performance.
Change the iPhone’s Display & Brightness setting from Dark mode to Light mode. A future app update will allow you to read the full menu in Dark mode.
