Coat the O-ring with the special grease.
To apply a uniformly thin layer of silicone grease to the O-ring, squeeze out about 5 mm (0.2 in.) of the grease provided with this product from the tube into a clean plastic bag (about 10 cm (3.9 in.) × 20 cm (7.9 in.) in size) and then knead it thoroughly. Put the O-ring into the plastic bag and continue kneading until the Oring is completely covered with grease. The plastic bag can be used more than once if kept clean.
Install the front-side O-ring (white).
For correct installation, observe the sticker (white) inside the waterproof case.
Place the front-side O-ring on the waterproof case beforehand to confirm that the O-ring is not twisted.
If it is not twisted, make sure that it is clean, with no foreign particles embedded in it or dust stuck to it, before installing it.
