● Rubber...gaskets
...
• The rubber gaskets of the au IC 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 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 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/au Style for the replacement of
parts.
