Install the O-ring.

Confirm that no foreign matter is attached, apply a thin coat of the accessory grease to the O-ring, and fit the O-ring into the groove. At this time, confirm that the O-ring does not stick out from the groove.

How to Apply Grease to the O-ring

Apply the1exclusive lubricant to each O-ring.Spread the2lubricant all over the O-ring.Check that the3O-ring is free of scratch or unevenness.Apply lubricant on4the O-ring contact surface.

Make sure that your fingers and the Oring are free of dirt, and squeeze about 5 mm of lubricant onto a finger. (5 mm is the most appropriate amount.)

Surround the lubricant with three fingers and spread it over the ring. Be careful not to use excessive force as this may stretch the O-ring.

After spreading the lubricant, check visually and by touch that the O-ring is not scratched and that its surface is flat. If it is damaged in any way, replace it with a brand-new O-ring.

Use the lubricant remaining on the fingers to clean and lubricate the case's contact surface.

CAUTION : • Always perform maintenance of the waterproof function even when the Case has been opened to exchange the battery or the image storage during shooting. Neglecting this maintenance may become the cause of water leakage.

When the Case is not to be used for a long time, remove the O-ring from the groove to prevent deformation of the O-ring, apply a thin coat of silicone grease, and store it in a clean plastic bag or the like.

When drying is done with salt attached, it is likely that a function impairment will be caused. After use, always wash off any salt.
