● Rubber gaskets
• The rubber gaskets of the au IC card/microSD memory card
tray play an important role for maintaining the waterproof
performance. Do not damage or remove the rubber gaskets.
• When closing the au IC card/microSD memory card tray,
take care not to get the rubber gaskets caught. Closing the
tray forcibly may damage the rubber gaskets causing the
waterproof performance to degrade. Even a fine debris (a
piece of hair, etc.) between contact surfaces may allow water
to enter the interior of the product.
• Liquid other than water (such as alcohol) adhered to the
product may cause the durability performance to degrade.
• Do not insert a sharp object into the gap between the au
IC card/microSD memory card tray. Doing so may damage/
deform the product or damage the rubber gaskets and may
allow water to enter the interior of the product.
• To keep the product waterproof, replacement of parts
is recommended every two years even if the product is
functioning normally. Contact your nearest au shop for the
replacement of parts.
