The internal vacuum pressure needs to be released before opening the housing. Use your fingertip to
move the yellow rubber one-way valve sideways to release the vacuum pressure. You and the valve area
must be dry!
11. If a "Leak Detected....pressure changed..." message appears during the 3.5 minute leak analysis, go back
to step 6. Inspect the O-rings for damage - replace O-rings if damaged. Clean the O-rings and repeat
steps 6 through 11.
Note
Make sure the housing temperature has adjusted to the surrounding air temperature. If the housing is
cooler than the air temperature, the air inside will expand, causing the leak analysis to fail.
You may disable the leak alarm in the app settings. Disabling the leak alarm will bypass the 3.5-minute
leak analysis described in step 11. If you disable the leak alarm, it is still important to apply internal
vacuum pressure, which helps the waterproof seal.
