How to attach the au IC card/microSD memory card tray
Insert the au IC card/microSD memory card tray in a straight
line all the way into the au IC card/microSD memory card slot
as shown in the diagram.
• If you turn the au IC card/microSD memory card tray upside down, the
au IC card may be dislodged.
• Do not wear gloves, etc. when you attach or remove the au IC
card/microSD memory card tray. Even a fine debris (a piece of
hair, etc.) between contact surfaces may allow water to enter
the interior of the product. If there is any water droplets or
debris on the tray, wipe them off completely with a dry clean
cloth before attaching it.
• Deterioration or damage of the au IC card/microSD memory
card tray will cause the waterproof performance to degrade.
● If any liquid other than water gets on the product
• In the event that the product comes into contact with liquid
other than water (seawater, detergent water, alcohol, etc.),
rinse it off immediately.
• You can wash the product under a mild flow (less than six liters
per minute) of tap water at room temperature (5℃ to 35℃ ) at
a distance of about 10 cm from the faucet or shower head.
• If the product gets dirty, wash it with your hands holding the
au IC card/microSD memory card tray so that it does not
open. Do not use a brush or sponge.
● If the product gets wet
• After the product gets wet, drain water and wipe the product
with a clean dry cloth.

• Water droplets adhered on the product may freeze in cold regions.
Continued use of the product in such condition may cause
malfunctions. Do not leave any water droplets on the product.
● 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.

hot airflow (from a hair dryer etc.) to it. This product is not
heat resistant.
