Using an anti-fog sheet (AKA-AF1)
When using the optional anti-fog sheet (AKA-AF1), place the camera in the waterproof case first, then insert the anti-fog sheet.
If you place the anti-fog sheet before placing the camera, the anti-fog sheet may be sandwiched and make it difficult to take out the camera.
Depending on the type of waterproof case, the place where the anti-fog sheet is inserted is different. Insert the anti-fog sheet into the side or bottom of the waterproof case.
Insert the anti-fog sheet indoors with low humidity.
Insert the anti-fog sheet in the camera a couple of hours before shooting.
If you do not use the anti-fog sheet, place it in a bag and keep the top sealed.
By drying the anti-fog sheet sufficiently, you can use it approximately 200 times repeatedly.
