1. Make sure you and the SportDiver housing are completely dry when releasing the vacuum pressure and opening the waterproof door. Releasing the pressure with a wet finger will result in water drops getting forcefully pulled into the housing, which may cause fogging on your next dive.
   
   
   
   
2. After use, dry the housing with a towel. Before opening the waterproof door, ensure you and the housing are completely dry. Open the door with the back of the housing facing down (lens facing up) to prevent water drops from entering the housing, which may cause fogging on your next dive.
   
   

The 5 gold-plated wet sensor contacts are located on the inside bottom right of the housing.  The leak alarm will activate if anything conductive (i..e. water drops, your finger, etc.) touches the wet sensor contacts.

If the leak alarm is activated, a “Leak Detected” message will appear on the display for 5 seconds and the housing will beep 5 times.  If this happens during your dive, surface SAFELY in accordance with safe diving practices. Power off the housing. Use a cotton cloth to clean and dry the housing and phone. Inspect the O-rings for damage, twisting and sand/hair/debris.  Clean and lube the O-rings or replace if damaged.

The purpose of the Leak Analysis is to check if the housing maintains an airtight seal before diving.  After sealing the housing and applying the vacuum pump pressure, the housing monitors the internal air pressure for any changes.  If the housing loses internal vacuum pressure, the phone will display “Leak Detected” or “Keep Pumping”, depending on the amount of pressure change.  If the housing maintains vacuum pressure, the leak analysis will be successfully completed, and the housing is ready for diving.   

Here are the most common causes for a loss of vacuum pressure resulting in leak analysis failure:

1. Changing air temperature inside the housing during the leak analysis will cause the vacuum pressure to change and may activate the alarm or “keep pumping” message. For example, if the housing is taken from a cool air-conditioned room to the warm outdoors.  If the housing is warming up during the leak analysis, the housing’s internal air expands causing vacuum pressure to drop and the leak analysis to fail.  Make sure to allow a cool housing to adjust to the warmer ambient temperature before starting the leak analysis.  Inserting a hot phone into the housing before starting the leak analysis will also cause thermal expansion inside the sealed housing and vacuum pressure drop.  A freshly charged phone may be hot.  Also, unused apps running in the background will draw battery power and generate heat.  Force off all apps running in the background, except for the SportDiver app. Also, allow a hot phone to cool down before starting the leak analysis.
2. One or both O-ring are not lubed, dirty or damaged. Clean the O-rings and apply very thin film of lube.  Replace the O-ring if cut or damaged in any way. One free O-ring set is included with each SportDiver Ultra. A spare O-ring set may be purchased at your local authorized SeaLife dealer. See item # SL40510.
3. The O-ring is installed incorrectly. The O-ring is “D”- shaped. The flat side of the O-ring must be against the O-ring groove with the round side facing outward.  Make sure the O-ring is not twisted.
4. The yellow one-way rubber valve at the vacuum check port is damaged or has some sand/debris trapped underneath. Clean the one-way valve using lint-free cloth moistened with alcohol. Use pressured air to blow out any sand/debris trapped underneath the one-way valve. If the one-way valve is damaged, contact the SeaLife Service Center in your country.

The SportDiver housing vacuum pressure check (leak analysis) works up to altitude of 6500 ft / 1980 m (11.6 psia). At higher altitude, the SportDiver LED status indicator will show red/green/yellow error code. 

When diving at altitudes higher than 6500 ft, you will need to disable the leak alarm in the SportDiver app Settings Menu.  Make sure you carefully set up the housing to avoid a leak – inspect, clean and lube O-rings, and properly seal the waterproof door.  You also need to add pumps of vacuum pressure after sealing the housing even though the leak alarm is disabled.  The vacuum pressure helps the waterproof door to fully seat itself into the housing, creating a strong seal.

The SportDiver app includes a Leak Alarm On/Off setting, however we do not recommend disabling the pre-dive vacuum pressure leak alarm unless diving at high altitude (See above).  If you decide to turn off the Leak Alarm setting for some other reason, please understand that you are doing so at your own risk.

Important: Turning off the Leak Alarm setting will only disable the 3.5-minute pre-dive vacuum pressure check.  The on-screen pressure gauge and “Keep pumping” message will not be displayed.  The wet sensor leak alarm cannot be turned off and will remain enabled. You should still add two to three pumps of vacuum pressure after sealing the housing.  The vacuum pressure helps the waterproof door to fully seat itself into the housing, creating a strong seal.

The internal vacuum pressure must be released before the housing can be opened.  Unscrew the vacuum check valve cap.  Use your dry 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 dull object, like a pen cap, to move the valve sideways.  Never use a sharp object near the rubber 1-way valve.
